Setting
Input speed commands using voltage values. The motor rotation speed and speed command
voltage are determined according to the value set in [SP51: Speed input factor].
The motor rotation direction is specified with the polarity of the speed command voltage and
[SP51: Forward start input setting] and [SP06: Reverse start input setting] and [SP50:
Command polarity].

The default setting for the value of [SP51: Speed input factor] is set according to
the max. rotational speed of the actuator combined with the driver.

The permissible max. rotational speed depends on the actuator. The default
setting for [SP51: Speed input factor] is set to the maximum value permitted by
the motor shaft. For details, refer to [Appendix-1 Factory settings] (PA-1).
