5.3.2. Motor connection / Winding protection
•
The electrical connection of the motor and the winding sensors is made by power connector or in the terminal box.
•
The motor cable must be shielded. Ensure that the cable shield contacts the frame over a large area at both ends.
•
The motor phases U1, V1 and W1 must be connected correctly to the corresponding phases of the inverter; they must
not be interchanged.
•
We recommend using a inverter with a switching frequency of 10 to 12 kHz.
•
The PTC resistor embedded in the winding must be evaluated in the control system or frequency inverter to protect
the motor from overtemperature.

The electrical connection of the motor and
the winding temperature sensors is made
by a rotatable 8-pole power connector
provided on the motor. A type B ST A
078 FR 05 08 0035 000 connector from
“intercontec” can be used, for example, as
the female plug.

PTC thermistors
•
The maximum operating voltage of the PTC thermis tors is not allowed to exceed 25 V DC
•
To achieve the maximum precision, the measurement voltage per PTC thermistor must not exceed 2.5 V DC.
Short-circuiting the motor terminals
•
The motor terminals of the synchronous lift machines, type WSG, can be short-circuited, if required, to brake the lift
machine faster.
•
However, this is only permissible at speeds less than or equal to the rated speed of the respective motor.
