5.5 DRIVE AND MOTOR CONNECTION
• The drive inherently produces fast switching of the output voltage
(PWM) to the motor compared to the mains supply, for motors which
have been wound for operation with a variable speed drive then there is
no preventative measures required, however if the quality of insulation
is unknown then the motor manufacturer should be consulted and
preventative measures may be required.
• The motor should be connected to the AD700E U, V, and W terminals
using a suitable 3 or 4 core cable. Where a 3 core cable is utilised, with
the shield operating as an earth conductor, the shield must have a
cross sectional area at least equal to the phase conductors when they
are made from the same material. Where a 4 core cable is utilised,
the earth conductor must be of at least equal cross sectional area and
manufactured from the same material as the phase conductors.
• The motor earth must be connected to one of the AD700E earth
terminals.
• For compliance with the European EMC directive, a suitable screened
(shielded) cable should be used. Braided or twisted type screened cable
where the screen covers at least 85% of the cable surface area, designed
with low impedance to HF signals are recommended as a minimum.
Installation within a suitable steel or copper tube is generally also
acceptable.
• The cable screen should be terminated at the motor end using an EMC
type gland allowing connection to the motor body through the largest
possible surface area
• Where drives are mounted in a steel control panel enclosure, the cable
screen may be terminated directly to the control panel using a suitable
EMC clamp or gland, as close to the drive as possible.
• For IP66 drives, connect the motor cable screen to the internal
ground clamp
5.6 MOTOR TERMINAL BOX CONNECTIONS
Most general purpose motors are wound for operation on dual voltage
supplies. This is indicated on the nameplate of the motor. This operational
voltage is normally selected when installing the motor by selecting either
STAR or DELTA connection. STAR always gives the higher of the two
voltage ratings.
