8 Motor control
This chapter contains all funcons and sengs relevant for the motor control.
Basic procedure of commissioning the motor control
In the rst step, the rated data of the motor must be set. The other steps depend on the
respecve applicaon case.
There are several opons for seng the motor data and opmising the control loops. Basi-
cally, you can select between a manual and an automac process. Whether a seng can be
applied or not depends on the motor (Lenze motor yes/no) and the applicaon. If possible,
always use the possible seng listed rst in the following diagram since this one leads to the
most accurate results.
Parameterisable functions:
V/f voltage boost, skip frequencies, optimisation of the stalling behaviour,
slip compensation, oscillation damping
Options:
V/f characteristic control (open-loop) (default setting), V/f characteristic control (closed-loop),
servo control, sensorless control, sensorless vector control
Possible settings:
a) Identifying data automatically (by inverter)
b) Calibrating data automatically (by inverter or engineering tool)
c) Loading preset inverter characteristics
Possible settings:
a) Identifying data automatically (by inverter)
b) Entering data manually
Possible settings:
a) Identifying data automatically (by inverter)
b) Entering data manually
Possible settings:
a) Identifying data automatically (by inverter)
b) Using data from the motor catalogue
c) Calibrating data automatically (by inverter or engineering tool)
d) Entering data manually
Possible settings:
a) Using data from motor catalogue
b) Entering data manually (e.g. from the nameplate)
