11.19 Addive voltage impression
This funcon serves to boost (or lower) the motor voltage from the process via an addive
voltage setpoint in order to realise a load adjustment (for instance in case of winder applica-
ons).
NOTICE
A too high boost of the motor voltage may cause the motor to heat up strongly due to the
resulng current.
▶
Avoid a too high boost of the motor voltage!
Details
At a constant eld frequency, the output voltage of the inverter can be changed within a wide
range.
Example: Adaptaon of the voltage characterisc in case of V/f characterisc control as a
funcon of the load:
•
Clockwise rotaon (CW) is operaon in motor mode: Boost voltage.
•
Counter-clockwise rotaon (CCW) is operaon in generator mode: Lower voltage.
