Effective Immediate
Analog torque command zero drift
compensation is to eliminate analog
torque command zero drift.
The setting method is as following:
（

）
Short-connect AI2 to AGND.
（
2
）
At the mode of analog torque, adjust
Po403 to make Lo-28 to 0.

When AI automatic zero set function is used, please make sure analog input is 0V. If zero drift is too big, servo
drive will trip into AL-21.
When using auto zero set function, make sure analog input is 0V, and set Po406 to 1, after about 3s, zero drift
will auto compensate.

This smoothens the speed command by applying a 1st-order filter to the analog speed command input. A value
that is too large, however, will slow down response.

Upper and lower limit setting of analog torque
The upper and lower limit setting of analog torque is the same with the setting method of analog speed mode,
the setting parameters are different.
