Overview of setpoint processing

The setpoint can be modified as follows using the setpoint processing:
● Invert setpoint to reverse the motor direction of rotation (reversing).
● Inhibit positive or negative direction of rotation, e.g. for conveyor belts, pumps or fans.
● Skip frequency bands to prevent mechanical resonance effects.
The skip frequency band at speed = 0 results in a minimum speed after switching on the
motor.
● Limit to a maximum speed to protect the motor and mechanical system.
● Ramp-function generator to accelerate and brake the motor with an optimum torque.

Invert setpoint

Procedure
Interconnect parameter p1113 with a binary signal,
e.g. digital input 1.
Table 8- 6
Parameter
p1113 = 722.1
p1113 = 2090.11

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