This parameter suppresses negative setpoints. Therefore, modification of the motor direction is inhibited to the setpoint channel.

Index:

P1110[0] : 1st. Command data set (CDS)

P1110[1] : 2nd. Command data set (CDS)

P1110[2] : 3rd. Command data set (CDS)

Common Settings:

0 = Disabled

1 = Enabled

Notice:

Where

-If a min. frequency (P1080) and a negative setpoint are given, the motor is accelerated by a positive value in relationship to the min. frequency.

-This function does not disable the "reverse command functions" (e.g. Reverse, ON left); rather, a reverse command causes motor to run in the positive direction only, as described above.
