Motor connection
CAUTION!
"
The drive must not be connected to the mains supply without a frequency inverter!
"
The motor is permitted to be used at frequency inverters with a maximum DC-link voltage
of < 750 V DC!
"
A shielded motor cable has to be used.
"
The screen has to be connected on both ends.
"
The maximum motor cable length is 25 m.
"
If no other agreement was met, the absolute encoder offset is set to 0 To do that, connect the
direct current with
U to +
and
V and W to -
.
"
The motor connection lines U, V and W have to be connected on the motor and inverter side to
the correct phases and must not be changed. Otherwise the motor may speed up uncontrolled.
"
The temperature monitoring of the motor has to connect to the frequncy inverter.
"
The admissible test voltage of temperature monitoring is maximum 2.5 V DC.
