2921491244.p65/2012047.4 Electrical design andconnector insert7.4.1 ZBF two-speed motor withbrakeThe motor has two separate windings and can be operated with two speeds.The GF combined brake module is used.Circuit diagram 038 682 84 shows the connection of a Z-type motor with twospeeds and brake. The DC brake is connected to the power supply of the motor viathe GF module.Additionally the GF module measures the motor current and switches the brake onthe DC side.Power is supplied to the motor and to the brake with the phases 1L1, 1L2 and 1L3via connections 1, 7 and 8 for high speed and via connections 1, 2 and 3 on theconnector for low speed.038 682 84Motor side Line sideThe module combines three functions in one unit. The module is used parallel to themotor winding. It is used for normal excitation of the DC brake. Additionally motor-current dependent brake switch-off in the DC circuit is integrated in the GF module.The GF module also features an integral varistor set that protects the high-polewinding.The GF combined module is used for pole-changing travel motors, sizes 63 - 100.7.4.2 GF combined brake moduleConnectors MotorHigh speedLowspeed2 windings, 2 speeds, 1 voltage Y/YCommon power supply of motor and GF brake control module |
