6.12.6 Canceling the operation command

H : Reverse-run prohibition

•Function

This function prevents the motor from running in the forward or reverse direction when it receives the wrong operation signal.

[Parameter setting]

Title	Function	Adjustment range	Default setting
		0: Forward/reverse run permitted
H	Reverse-run prohibition	1: Reverse run prohibited	0
