The holding brake circuit in the "released" state before powering on
Source: InternetPublisher:D先生 Keywords: Brake circuit motor power supply Updated: 2021/05/23
The circuit is shown in Figure 3-123. When the stop button SBz is pressed, the contactor KMi is released, cutting off the power supply to the motor . At the same time, KMz is closed, turning on the power supply of the
electromagnetic brake YB , and braking the motor "tightly". After a period of delay,
the time relay KT delays closing and the normally closed contact opens, KM2 is released, and the circuit returns to the state before starting.
