CHAPTER 4 PARAMETER
4-98
Input Terminal Function Setting Parameter
4
Functions that may not be specified with a normally closed signal include forced stop and external
regenerative resistor overheat. (Functions that can be specified with a normally closed signal are
+OT and -OT.)
For example, to turn forward command [FWD] always on, specify "2," which corresponds to the
forward command, to one of CONT always ON signals 1 to 5.
The signal assigned to CONT input signal can be also assigned to CONT always enabled setting
redundantly.
PA3_31 to 34 Speed and torque command scale and offset settings
No. Name Setting range Default value Change
31
Speed command scale ±1.0 / to ±100.0 [V]/ Rated rotation

10 mV] Shipment setting Always
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 to 500 [r/min] 0 Always
The parameter is enabled under speed or position control.
Rotation speeds less than the specified value are clamped (fixed) at 0 r/min.
This parameter is not affected by offsets or similar for the prevention of drifting upon nearly zero speed
command input value.
PA3_36 Deviation clear input form
No. Name Setting range Default value Change

0: Edge 1: Level 0 Power
Specify the deviation clear input signal format.
Select 0 (edge) to reset position deviation at the rising edge timing.
