/ 081
Data range : from –20 to +20
Standard : 0
You should not change this parameter from standard setting value.
If the current offset caused the torque ripple of a quarter every one motor revolution because of noise, you
could set this parameter to improve it.
Data range : from 0 to Velocity feedback pulses (No.2023)
Standard : 0
In case that you use outer serial scale, you should set this parameter if position feedback pulses
(No.2024) is above 32767. Refer to example 5 in 5.1.3 Setting servo parameters.
(Position feedback pulses) = (No.2024) × (No.2185)
Data range : 0 to 2048 ( mean 0 to 0.5)
Standard : 0
You should not change this parameter from standard setting value.
The increase of this parameter fasten the response of current loop trading off the stability of current.
Data range : 0 to 32767
Standard : 0
Use this function in case of full-closed system whose linear scale has lower limitation of speed than that
of the motor. If this function is used and then it detected, you can use the stop control at the alarm
(No.2005#6) of which kind are MSCHK alarm as well as OVL alarm.
Setting value: MSCKLV= L/B x 6554
L : detective level for the scale (mm/sec), B: ball screw pitch (mm/rev)
