Functional description
This control PCB with starter relay and integrated brake control is used for single-phase 230 V DC capacitor motors with a capacity < 3.0 kW. The motor is driven, as long as the on-signal is applied. Resetting the on-signal triggers the braking phase. Since all safety-relevant switching sequences are operated by a controller, a restart can be carried out at any time during the braking operation.
Motor heating during brake operation
The motor heating during braking with DC correlates with the heating during motor start. If a motor is frequently started and stopped a temperatur should be mointored by a thermistor.
Adjusting brake current
The braking current depends on the motor and flywheel mass. It can be adjusted with a potentiometer. Our experience from several projects in the past shows that it is reasonable to test the motors and its flywheel mass in our development centre when production quantities warrants this additional effort to ensure the optimum adjustment of the brake. On request external adjustment of the brake can be realised for all our available switches.
We have profound experiences in braking moduls for many years. That's why we are the right partner for electronic brakes.
