Invert setpoint

The inverter provides an option to invert the setpoint sign using a bit. As an example, the
setpoint inversion is shown through a digital input.
In order to invert the setpoint through the digital input DI 1, connect the parameter p1113
with a binary signal, e.g. the digital input 1.
Table 8- 9
Parameter
p1113 = 722.1
p1113 = 2090.11
8.4.3

Inhibit direction of rotation

In the factory setting of the inverter, both motor directions of rotation are enabled.
Set the corresponding parameter to a value = 1 to permanently block directions of rotation.
Table 8- 10
Parameter
p1110 = 1
p1110 = 722.3

Examples of settings to invert the setpoint
Remark
Setpoint inversion
Digital input 1 = 0: Setpoint remains unchanged.
Digital input 1 = 1: Inverter inverts the setpoint.
Invert setpoint via control word 1, bit 11.
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.
