3-16 Basic Installation
MN1902
3.5.1 Motor circuit contactors
If required by local codes or for safety reasons, an M-Contactor (motor circuit contactor) may
be installed to provide a physical disconnection of the motor windings from the FlexDrive
II
(see section 3.5). Opening the M-Contactor ensures that the FlexDrive
II
cannot drive the
motor, which may be necessary during equipment maintenance or similar operations. Under
certain circumstances, it may also be necessary to fit a brake to a rotary motor. This is
important with hanging loads where disconnecting the motor windings could result in the load
falling. Contact your local supplier for details of appropriate brakes.
CAUTION
: If an M-Contactor is installed, the FlexDrive
II
must be disabled at least
20ms before the M-Contactor is opened. If the M-Contactor is opened
while the FlexDrive
II
is supplying voltage and current to the motor, the
FlexDrive
II
may be damaged. Incorrect installation or failure of the
M-Contactor or its wiring may result in damage to the FlexDrive
II
.
Ensure that shielding of the motor cable is continued on both sides of the contactor.
