MOVIMOT® (→ MM)
Project Planning for AC Motors
4Q operation with
integrated braking
resistor BW..
• The brake resistor is integrated in the terminal box of MOVIMOT
®
as standard in
motors without mechanical brake.
• 4Q operation with integrated braking resistor is recommended for applications in
which the level of regenerative energy is low.
• The resistor protects itself (reversible) against regenerative overload by changing
abruptly to high resistance and no longer consuming any more energy. The inverter
then switches off and signals an overvoltage error (error code 04).
• Field distributors or P2.A option for mounting the MOVIMOT
®
unit in close proximity
to the motor, the braking resistor must be ordered separately.
