8.16.2
Integration
It must be installed according to the connection schematic VPM 120 (Fig. 8-42)
or VPM 200/200 Dynamic (Fig. 8-43).
Series reactors may only be connected between the VPM and motor.
Clearances of approx. 200 mm must be provided above and below the unit for
cable entry.
It can be mounted in any position.
It is not permissible that switching elements are inserted in the connecting
cables U, V ,W between the drive, VPM and motor!
The air intake temperature, measured 10 mm below the unit, may not exceed
55
°
C.
Caution
After switching off all of the voltages, hazardous voltages are present for up to
4 minutes (capacitance of the 611 converter capacitor). The voltage must be
measured to ensure that there are no hazardous voltages present!
Notice
The unit is a safety–relevant piece of equipment and may only be used as
specified. Other application, e.g. armature short–circuit in operation and others
are not permissible.
The warning information on the unit must be carefully observed!
Operation with VPM is only permitted in conjunction with the
SIMODRIVE 611 digital, SIMODRIVE 611 universal, converter system,
shielded Motion-Connect 800 motor supply cables, and enabled
permanent–magnet induction motors.
!
Warning
Motors with an EMF that can achieve a DC link voltage > 2 kV (EMF = 1.4 kV
eff) at the highest speed are not permitted to be connected to the SIMODRIVE
611. In this case, the insulating voltage could be exceeded, resulting in
personal injury due to electric shock.
Voltages U
2 kV can occur at cables/conductors that are cut or damaged.
In the event of an error, the terminal voltage of the permanent–magnet
induction motors can assume values U
2 kV.
Hazardous voltage is still present approximately 4 minutes after all voltages
have been shut down (capacitor capacity of the SIMODRIVE 611 converter). In
order to ensure that no hazardous voltages are present, the voltage must first
be measured.
