34 Torque command offset -2000 [mV] to 2000 [mV] Shipment setting
Specify the scale (gain) and offset of the analog input signal.
PA3_35 Zero clamp level
No. Name Setting range Default value Change
35 Zero clamp level 0 [r/min] to 500 [r/min] 0 Always
Rotation speeds less than the specified value are clamped (fixed) at 0 [r/min].
This is used in such cases as when wishing to avoid the influence of offsets, etc. on analog input
voltage used for the speed command value or speed limit value.
