UNDESIRABLE EFFECTS OF MOTOR CABLES LONGER THAN 25 M
♦
Heating of the power module, the motor and the cable.
♦
High overvoltages on the motor windings involving a shortening of their life time.
The reactance reduces the undesirable effects on motor and drive but it may be quite heated. This requires an
appropriate fan.
4.6 – SERIAL LINK AND CAN COMMUNICATION CABLES
Serial link and CAN communication cables must also be shielded according to the shield connection
recommendations above.
CAUTION !
Control cables (resolver, serial link, CAN) and power cables must be connected and
disconnected with the drive OFF.
Recall:
The power voltage may remain several minutes at the capacitors terminals. A contact under
high voltage may involve severe physical damage.
4.7 – CONNECTION CABLES OF THE BRAKING RESISTOR
The connection cable to the braking resistor housing must bear the high voltage and temperature of 600 V and
105°C.
Recommended cable: UL1015 Gauge 14.
Tightening torque on the connector of the braking resistor housing: dp = 0.9 Nm.

ERY IMPORTANT
Check the connections, especially of the 24 V
230 V
and 400 V
. Check that the appropriate sticker actually corresponds to the power connections.

AC
The 400 V
connection of a 230 V drive will destroy it.
AC
The ENABLE signal (X2 connector, pin 1) must be disabled.
Any braking resistor value lower than the minimum value specified in the technical specifications wil definitely
damage the braking system.
Check for the correct groundings as well as the 360° shield connections.
WARNING !
During the machine adjustments, drive connection or parametrization errors may involve
dangerous axis movements. It is the user's responsibility to take all necessary steps in order to
reduce the risk due to uncontrolled axis movements during the operator's presence in the
exposed area.
