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 enable the negative direction of rotation:
Set parameter p1110 to a value = 0.
The positive direction of rotation is enabled in the factory setting; you can inhibit this direction
of rotation using p1111 = 1.
Table 7- 16
Parameter
p1110 = 1
p1110 = 722.3
7.4.4

Minimum speed

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 acceler-
ating or braking.
Table 7- 17
Parameter
p1080
p1106
The minimum speed is formed from the parameters p1080 and p1106, where the larger
value determines the effective minimum speed.

Examples of settings to inhibit the direction of rotation
Remark
Inhibit negative direction
Negative direction is permanently inhibited.
Inhibit negative direction
Digital input 3 = 0: Negative direction of rotation is enabled.
Digital input 3 = 1: Negative direction of rotation is inhibited.
