Control Table

Control Table consists of data regarding the current status and operation of CM-730. The user can control CM-730 by changing data of Control Table via Instruction packet.

EEPROM and RAM

Data in RAM area is reset to initial values whenever the power is turned on while data in EEPROM area is kept once values are set even if the power is turned off.

Address

Represents the location of data. To read from or write data to the control table the user should assign the correct address in the Instruction packet.

Access

CM-730 has two kinds of data: Read-only data, used mainly for sensing, and read-and-write data used for driving.

Initial Value

In case of data in the EEPROM Area, the initial values on the right side of the below Control Table are the factory default settings.
In case of data in the RAM Area, the initial values on the right side of the following control table are the ones when the power is turned on.

Highest/Lowest Byte

In the Control table, some data share the same name, but they are attached with (L) or (H) at the end of each name to distinguish the address. This data requires 16-bit, but it is divided into 8bit each for the addresses (low) and (high). These two addresses should be written with one Instruction Packet simutaneously.
