Information/possible settings
Additive voltage impression
• An additional setpoint for the motor voltage can be specified via this process

input.
• If there are, for instance, different loads at the motor output end, it is possible to
apply a voltage boost at the starting time.
• If the value is negative, the voltage is reduced.
• Scaling: 16384 ≡ 1000 V

Stop!
Values selected too high may cause the motor to heat up due to the resulting
current!
AutoBoost function
• Motor voltage boost during the starting torque, controlled by process signals

from the function block interconnection.
FALSE Deactivate function
TRUE Activate function
Additional setpoint for the motor voltage at speed = 0
• The entire voltage-frequency characteristic is provided with an offset.

Position/angle control
C00833/27 | BOOL
FALSE Deactivate position/angle control.
TRUE Activate position/angle control.
Activate position difference as setpoint selection

TRUE Positioning with speed setpoint nSpeedSetValue_a and position
Position difference (following error input)
• Difference between setpoint position and actual position in [increments]
C00834/4 | DINT
• Is used for position control

Position control/additive speed
• The absolute position setpoint dnPosSetValue_p is differentiated
and a speed value is created which is the setpoint for the speed
controller.
