Parameter ID 8 Parameter
Name Total Inertia
Data Total inertia (Unit: 0.01 gf・cm2)
Return Value 0: Parameter setting successful
1: Parameter setting unsuccessful
Explanation This parameter is used to set the inertia due to the motor rotation shaft and the mirror.
Note: Be careful about the unit. Set a value of gf・cm2 multiplied by 100.

Parameter ID 9 Parameter
Name Motor Current Limit
Data Motor Current limit (Unit: %)
Return Value 0: Parameter setting successful
1: Parameter setting unsuccessful
Explanation This parameter is used to set the upper limit of a current command value. (Setting for
each axis as a ratio to 10A)
E.g.: 90% (10A × 0.9 = 9A)
If the current remains over the upper limit for a specified time, a current saturation error
occurs.

Bit 15 “Current Saturation” becomes 1 in error read (Command ID = 15).
Parameter ID 10 Parameter
Name Encoder Wave per Rotation
Data Encoder periodicity (Unit: pulse)
Return Value 0: Parameter setting successful
1: Parameter setting unsuccessful
Explanation This parameter is used to set the number of pulses per rotation of the motor encoder.
GM-1010: 1000 pulses
GM-1015: 1500 pulses
Whenever the motor model is changed, the setting of this parameter should be
changed.
