For protecting the motor, set the current limit
values "I

current" (C0022, C0023)
Guide value
£ 2−fold rated motor current
Power range 0.37 ... 90 kW:
For dissipating the regenerative energy,
use a brake chopper or feedback
module, if necessary
Power range 110 ... 400 kW:
For dissipating regenerative energy, use
a brake resistor, if necessary

In motor mode and generator mode (C0022)
B
Additional limitation in generator mode (C0023)
Condition: C0023 < C0022
12.
If the motor temperature is monitored with a
thermal sensor KTY:
Activate the temperature feedback with C0594
(fault SD6)
Lenze setting: 3 (switched off)
A temperature feedback with KTY has a
positive effect on the vector control,
since the motor data identification
considers the temperature influence in
the motor model.
