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

Motor brake switching threshold 100/i 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 prevented.

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 max. 40 W if the mean speed is > 1000 rpm
(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] % For the suppression of no-load oscillaons. Typically, the impact has
to be increased for this purpose.

•
That the drive does not show any visible signs of damage.
•
Is the mechanical xing o.k.?
•
Is the electrical connecon o.k.?
•
Are all rotang parts and surfaces that may become hot protected against contact?
•
Is the featherkey radially secured during the test run without output elements?
•
Have all screwed connecons of the mechanical and electrical parts been ghtened?
•
Is the free supply and removal of cooling air ensured?
•
Has the PE conductor been connected correctly?
•
Have the protecve devices against overheang (e.g. temperature sensor evaluaon) been
acvated?
•
Is the contact of good electrical conducvity if a PE connecon on the motor housing is
used?
Aer a long period of downme or aer overhauling the motor, check the insulaon
resistance prior to inial switch-on, as condensaon may have formed.
•
If the values measured are ≤1 kΩ per volt of the rated voltage, the insulaon resistance is
inadequate and no voltage is to be applied.
•
Dry the winding unl the insulaon resistance is >1 kΩ per volt of the rated voltage.
