4-1-4 Checking Servomotor Parameters (Cn-00 Set to 04)
Servomotor parameters can be checked when system check mode Cn-00 is set to “04.”
Servomotor parameters are the Servomotor specifications that can be controlled by that
Servo Driver. They are not the specifications of the Servomotor that is connected. Use
this to check whether the Servo Driver and Servomotor combination is suitable.
