•
Boost of the motor voltage in the range of low speeds.
•
In the case of conveyor applicaons with an inclined pro-
poron, a turn-back during start-up can be prevented.
•
Typical values approx. < 5%.

With a gearbox, the seng range can be smaller.
Reducing the I

causes a lower maximum torque.
Drives coupled mechanically No No, yes Reducing compensaon processes in case of heavy and long

Motor brake switching
threshold
100 rpm [0 ... 499.9/i] rpm Motor brake is switched if the value is exceeded or is too
low.
Higher value: In the case of conveyor applicaons with an
inclined proporon, a turn-back during start-up can be pre-
vented.

Enter data of a connected brake resistor correctly.
If ed in the factory:
•
If an internal brake resistor is used, the values of the
brake resistor are preset.
•
If an external brake resistor is used, the values of the
brake resistor are preset. Only the rated power can be
increased from 20 W to a maximum of 40 W if the mean
speed is > 1000 r/min (mathemacal mean of the process
speeds in relaon to the motor speed, without standsll).

Reducon of brake chopper
threshold
0 V [0 ... 150] V The threshold is reduced by the voltage value set here.
The switching threshold is adapted to the dierent mains
voltage ranges.
Reducon by 20 ... 30 V can prevent overvoltage for opera-
on in generator mode.
Impact of oscillaon damping 5.00 % [0.00 ... 250.00] % To suppress idle oscillaons. Typically, the impact has to be
increased for this purpose.
