Maximum motor cable length
Keep the motor cable as short as possible since this has a positive effect on the drive
ƒ
behaviour.
The maximally permissible motor cable length is: 20 m, shielded
ƒ
– at rated mains voltage
– at a switching frequency of 8 kHz
)
Note!
If the conditions for electromagnetic compatibility must be observed, the
permissible cable lengths may vary.

Motor protection
Extensive protection against overload:
ƒ
– By overcurrent relays or temperature monitoring.
– We recommend the use of PTC thermistors or thermostats to monitor the motor
temperature.
– PTC thermistors or thermostats can be connected to the controller.
– For monitoring the motor, we recommend the use of the I
Only use motors with an insulation suitable for the inverter operation:
ƒ
– Insulation resistance: min. û = 1.5 kV, min. du/dt = 5 kV/ms
– When using motors with an unknown insulation resistance, please contact your
motor supplier.
