(May cause injury or damage to product)

  • Do not operate product at temperature below 5 degrees or above 55 degrees.
  • Do not insert sharp blades nor pins during product operation.


ATTENTION
(May cause injury or damage to product)

  • Do not disassemble or modify product.
  • Do not drop or apply strong shock to product.

Performance Graph

NOTE : The max torque measurement method for the Stall Torque and Performance Graph is different.
Stall torque is measured from the max torque that it can reach. This is generally how RC servos measure their torque.
For the Performance graph with the N-T curves, it is measured with the load gradually increasing.
The motor operation environment is closer to the performance graph, not stall torque method.
This is probably why the performance graph is being broadly used in the industrial market.
This is why the max torque of the performance grap can actually be less than the stall torque.

CAUTION : When supplying power

  • It is recommended using ROBOTIS controller or SMPS2DYNAMIXEL.
  • Do not connect or disconnect DYNAMIXEL when power is being supplied.

Control Table

The Control Table is a structure of data implemented in the DYNAMIXEL. Users can read a specific Data to get status of the DYNAMIXEL with Read Instruction Packets, and modify Data as well to control DYNAMIXEL with WRITE Instruction Packets.

Control Table, Data, Address

The Control Table is a structure that consists of multiple Data fields to store status of the DYNAMIXEL or to control the DYNAMIXEL. Users can check current status of the DYNAMIXEL by reading a specific Data from the Control Table with Read Instruction Packets. WRITE Instruction Packets enable users to control the DYNAMIXEL by changing specific Data in the Control Table. The Address is a unique value when accessing a specific Data in the Control Table with Instruction Packets. In order to read or write data, users must designate a specific Address in the Instruction Packet. Please refer to Protocol 2.0 for more details about Instruction Packets.

NOTE : Two’s complement is applied for the negative value. For more information, please refer to Two’s complement from Wikipedia.

Area (EEPROM, RAM)

The Control Table is divided into 2 Areas. Data in the RAM Area is reset to initial values when the power is reset(Volatile). On the other hand, data in the EEPROM Area is maintained even when the DYNAMIXEL is powered off(Non-Volatile). Data in the EEPROM Area can only be written to if Torque Enable(562) is cleared to ‘0’(Off).

Size

The Size of data varies from 1 to 4 bytes depend on their usage. Please check the size of data when updating the data with an Instruction Packet. For data larger than 2 bytes will be saved according to Little Endian.

Access

The Control Table has two different access properties. ‘RW’ property stands for read and write access permission while ‘R’ stands for read only access permission. Data with the read only property cannot be changed by the WRITE Instruction. Read only property(‘R’) is generally used for measuring and monitoring purpose, and read write property(‘RW’) is used for controlling DYNAMIXEL.

Initial Value

Each data in the Control Table is restored to initial values when the DYNAMIXEL is turned on. Default values in the EEPROM area are initial values of the DYNAMIXEL (factory default settings). If any values in the EEPROM area are modified by a user, modified values will be restored as initial values when the DYNAMIXEL is turned on. Initial Values in the RAM area are restored when the DYNAMIXEL is turned on.

The External Port is not electrically insulated, therefore, abide by the electrical specifications.
If the electrical specification is exceeded or there is a problem with the signal connection, special caution is required because DYNAMIXEL can be damaged.

  • Be careful not to cause electric shock by static electricity (ESD), short circuit, open circuit.
  • Be careful not to let water or dust get into the External Port connector.
  • If you are not using the External Port, remove the cable.
  • To connect or disconnect the External Port, proceed with power off.
  • Do not connect the GNDext pin of External Port directly to the GND pin of DYNAMIXEL connector. Noise from power may affect on the External Port.

Shutdown(48)

The Dynamixel can protect itself by detecting dangerous situations that could occur during the operation. Each Bit is inclusively processed with the ‘OR’ logic, therefore, multiple options can be generated. For instance, when ‘0x05’ (binary : 00000101) is defined as Shutdown(48), Dynamixel can detect both Input Voltage Error(binary : 00000001) and Overheating Error(binary : 00000100). If those errors are detected, Torque Enable(562) is cleared to ‘0’ and the motor output becomes 0[%]. In order to reuse Dynamixel Pro in shutdown status, REBOOT has to be done. The followings are detectable situations.

Bit Item Description
Bit 7 - -
Bit 6 - -
Bit 5 Overload Error(default) Detect persistent load that exceeds maximum output
Bit 4 Electrical Shock Error(default) Detect electric shock on the circuit or insufficient power to operate the motor
Bit 3 Motor Encoder Error(default) Detect malfunction of the motor encoder
Bit 2 OverHeating Error Detect internal temperature exceeds the configured operating temperature
Bit 1 Motor Hall Sensor Error(default) Motor hall sensor value exceeds normal range
Bit 0 Input Voltage Error Detect input voltage exceeds the configured operating voltage

NOTE : If Shutdown occurs, use below method to reboot Dynamixels.

  1. H/W REBOOT : Turn off the power and turn on again
  2. S/W REBOOT : Transmit REBOOT Instruction (For more details, please refer to the Reboot section of e-Manual.)

Indirect Address, Indirect Data

Indirect Address and Indirect Data are useful when accessing two remote addresses in the Control Table as sequential addresses. Sequential addresses increase Instruction Packet efficiency. Addresses that can be defined as Indirect Address is limited to RAM area(Address 562 ~ 892). If specific address is allocated to Indirect Address, Indirect Address inherits features and properties of the Data from the specific Address. Property includes Size(Byte length), value range, and Access property(Read Only, Read/Write). For instance, if address 563(LED Red) is allocated to Indirect Address 1(49), Indirect Data 1(634) will have the exactly same value of LED Red(563).

Example 1

Allocating 1 byte LED(563) to Indirect Data 1(634).

  1. Indirect Address 1(49) : change the value to ‘563’ which is the address of LED Red.
  2. Set Indirect Data 1(634) to ‘1’ : LED Red(563) also becomes ‘1’ and Red LED will be turned on.
  3. Set Indirect Data 1(634) to ‘0’ : LED Red(563) also becomes ‘0’ and Red LED will be turned off.

Example 2

Allocating Size 4 byte Goal Position(596) to Indirect Data 2(635), 4 sequential bytes have to be allocated.

  1. Indirect Address 2(51) : change the value to ‘596’ which is the first address of Goal Position.
  2. Indirect Address 3(53) : change the value to ‘597’ which is the second address of Goal Position.
  3. Indirect Address 4(55) : change the value to ‘598’ which is the third address of Goal Position.
  4. Indirect Address 5(57) : change the value to ‘599’ which is the fourth address of Goal Position.
  5. Set 4 byte value 305,419,896(0x12345678) to Indirect Data 2 : Goal Position(596) also becomes 305,419,896(0x12345678) as below.
Indirect Data Address Goal Position Address Saved HEX Value
635 596 0x78
636 597 0x56
637 598 0x34
638 599 0x12

NOTE : In order to allocate Data in the Control Table longer than 2[byte] to Indirect Address, all address must be allocated to Indirect Address like the above Example 2.

NOTE : Indirect Address 29 ~ 56 and Indirect Data 29 ~ 56 can only be accessed with Protocol 2.0.

Torque Enable(562)

Controls Torque ON/OFF. Writing ‘1’ to this address will turn on the Torque and all Data in the EEPROM area will be protected.

Value Description
0(Default) Torque OFF(Free-run) and the motor does not generate torque
1 Torque ON and all Data in the EEPROM area will be locked

NOTE : Present Position(132) can be reset when Operating Mode(11) and Torque Enable(64) are updated. For more details, please refer to the Homing Offset(20) and Present Position(132).

RGB LED(563)

Controls the RGB LED on Dynamixel PRO.

Address Color Range
563 Red 0 ~ 255
564 Green 0 ~ 255
565 Blue 0 ~ 255

NOTE : The LED indicates present status of the device.

Status LED Representation

Velocity PI Gain(586, 588)

These values indicate P and I Gains of Velocity Control Mode. The I Gain includes sampling time. Velocity P Gain of DYNAMIXEL’s internal controller is abbreviated to KVP and Velocity I Gain is abbreviated to KVI.

Gain Value Range
0 ~ 32,767

NOTE : KPA stands for Anti-windup Gain that cannot be modified by users. For more details about the PID controller, please refer to the PID Controller at wikipedia.

Position P Gain(594)

This P Gain is used in Position Control Mode. Below figure is a block diagram describing the Position Control Mode. The Position Controller is cascaded with the Velocity Controller. KPP stands for Position P Gain.

Gain Value Range
0 ~ 32,767

Goal Position(596), Present Position(611)

Desired position can be set with Goal Position(596). This value can’t be smaller than the Min Position Limit(40) or larger than Max Position Limit(36).

Model Angle Range Position Range Description

H42-20-S300-R -180° ~ 180 ° -151,875 ~ 151,875

Goal Velocity(600)

Goal Velocity(600) can be used to set a desired velocity and this value cannot exceed Velocity Limit (32). In case of Position Control Mode or Extended Position Control Mode, Goal Velocity will be used to limit the velocity. However, if Goal Velocity is set to ‘0’, Velocity Limit(32) will be used to limit the velocity. (Please refer to the block diagram of Position P Gain) The Goal Velocity stands for the RPM of the motor before the reduction gears and output RPM after the reduction gears can be calculated using below scale factor. Output RPM = Goal Velocity * Scale Factor

Goal Torque(604)

Goal torque (604) can be used to set a desired torque and this value cannot exceed Torque Limit(30). When the Operating Mode(11) is set other than Torque Control Mode, Goal Torque will be used to limit the torque. However, if Goal Torque is set to ‘0’, Torque Limit(30) will be used to limit the torque. (Please refer to the block diagram of Position Gain or Velocity Gain) The relationship between torque, current, and goal torque is shown below.

Model Formula
PRO 54 A = C x 33,000 ÷ 2,048
A = Current on Motor Coil[mA]
C = Present Current(621) or Goal Torque(604)
PRO 42 A = C x 8,250 ÷ 2,048
A = Current on Motor Coil[mA]
C = Present Current(621) or Goal Torque(604)

Goal Acceleration(606)

Goal Acceleration(606) can be used to set a desired acceleration. This value is used in Velocity Control Mode, Position Control Mode and Extended Position Control Mode. The profile control will be enabled when both Goal Acceleration(606) and Goal Velocity(600) are not ‘0’. Please refer to the Goal Velocity(600) for RPM conversion constant.
