Manual

Register Map are values residing within the Servo and contain data pertaining to current servo
status and operation. Registers are either Non-Volatile or Volatile.
Users are able to control the servos by using Request Packet and ACK Packet to either check or
change the data in the Register Map.
Address refers to the address of the Register. To Read/Write to the Register, Register address must be
included in the Packet.
Address
Factory Default Value, Rollback Protocol is used to return all values to Factory Default Value.
Default
Range of valid data values servo can have. Input of data beyond the Valid Range will possibly result
in unpredictable servo behavior.
Valid Range
RO refers to read only Registers. Writing to RO Register will result in error.
RO Registers hold fixed values such as Model #, Version or sensor values used for feedback.
RW refers to Registers which be both read and written to.
※ e (Reg_Name) : Refers to Reg_Name in EEP Register.
※ r (Reg_Name) : Refers to Reg_Name in RAM Register.

4-2. Register Map
Non-Volatile memory retains data without power. Once the power is turned on, data in the Non-Volataile
memory in EEP Register are copied to the RAM Register which is Volatile memory. Data in the Non-Volatile
memory does not have direct affect on the operation of the servo once it has been copied to the RAM
Register. Rebooting the servo will again copy the data from EEP Register to the RAM Register.
