Enclosure
Alternative ground connection
Bond the armour or shield to the back-plate.
If the enclosure construction permits, you may
instead bond the armour or shield to the enclosure at
the cable entry point.
Refer to
Radiated emissions in the EMC Data Sheet.
Do not connect the
cable shields to the
resolver or motor.
Connect the cable
shields to terminal
B18 (0V connection).
Refer to the signal
connections diagram.
Preferred motor and braking resistor connections
Motor directly connected to the Drive.
Wiring to optional braking resistor contained within the enclosure and the
resistor shielding.
