Motor Circuit Information
The SEW-Eurodrive MOVIMOT® is used in many high speed reversing (and non-reversing)
applications, such as the transfer drive for the PolySort. The MOVIMOT® as provided by TGW would
typically consist of the following:
- Three phase induction motor with an integrated variable frequency drive
- Speed control potentiometer, built into drive housing.
- Dynamic braking resistor, preinstalled in the drive.
Additional hardware required for control of the MOVIMOT® would include:
- Lockable, fused disconnect switch for each drive.
- Motor contactor for each system.
- 24V Control Power Supply
- 24VDC PLC output (PNP sourcing) for run command (two for reversing).
High Voltage Connections
- Verify that the motor nameplate rating matches the system voltage and frequency.
- Size fuses as for a conventional induction motor.
- Terminals for 3 phase power are located inside the connection box on the motor.
- Group motor installations are not permitted.
- A contactor before the fused disconnect switches must be used. This should be energized with the
Master Control Relay (MCR) for the system and not used for normal motor stopping.
- Connect conductors to the L1, L2, L3 and ground terminals. See figure 1 below.
Controls Connections
- Connect dry contacts between the 24VDC and R
⟳
and/or L
⟲
terminals. These signals will start and
stop the motor in the clockwise or counter-clockwise directions. See figure 1.
-
Connect the external power to the 24V and ┴ terminals. Connect
PLC outputs to the R
⟳
and/or L
⟲
terminals (PNP sourcing outputs).
