AKD™ Installation Manual - TG Drives

AKD Installation | 6 Technical description and data6.16.4 Implementation of Stop Category 1Bringing the motor to a standstill by interrupting the mains supply and using controlled electronic braking (DRV.DISMODE must be set to 2). The 24 V supply for the AKD must remain constant.The drive is braked in a controlled manner during the stopping (disabling) procedure. If the speedCS.VTHRESH (sequence diagram: see page 1) is undershot, the holding brake is applied and the outputstage is disabled. As soon as two separate time periods (set at the time relay) have elapsed, the mains supplyand the holding brake are electrically isolated.Should an internal AKD fault occur, the motor is forced to a standstill once theAKD drops out. Make sure that the machinery cannot be damaged by forced braking.Forced braking with the built-in motor holding brake can damage the brake.Circuit suggestion (with EMERGENCY STOP Category 1, control function with contactor relays)52 Kollmorgen | December 2009
