This is not recommended. As the drive reverses, the frequency ramps through zero without operating the holding brake. This may cause problems in an installation where loss of torque at low speed could result in loss of control.A better solution is to use RUN right and RUN left commands to control the direction of the motor rotation. Using this control method, the holding brake will always be enabled at the minimum frequency when and OFF or RUN command is given. This ensures the motor is fully fluxed and able to deliver full torque when the brake is release.Brake Operation Using RUN left, RUN rightNote that the RUN left signal must be applied after the drive has come to a stop; that is, a RUN left signal is not recognized while the drive is still running right.
