Enable direction of rotation
In the factory setting of the inverter, the negative direction of rotation of the motor is inhibited.
Proceed as follows to permanently enable the negative direction of rotation:
Set parameter p1110 to a value = 0.
You have permanently enabled the negative direction of rotation.
Table 8- 16 Examples of settings to inhibit the direction of rotation
p1110 = 1
Inhibit negative direction
Negative direction is permanently inhibited.
p1110 = 722.3
Inhibit negative direction
Digital input 3 = 0: Negative direction of rotation is enabled.
Digital input 3 = 1: Negative direction of rotation is inhibited.
The inverter prevents continuous motor operation
at speeds <
minimum speed.
Speeds, where the absolute value is less than the
minimum speed, are only possible when
accelerating or braking.
