VFD-F Series5.9 Group 8: Special Parameters08 - 00 DC Brake Current Level Factory Setting: 00Settings 00~100% Unit: 1 This parameter determines the level of DC brake current output.08 - 01 DC Brake Time during Start-up Factory Setting: 0.0Settings 0.0~60.0 Sec Unit: 0.1 This parameter determines the duration of time that the DC brake current will be applied tothe motor during the AC drive start-up. The motor may rotate by external force or inertia itself before operating. It may damage themotor or start the AC drive protection function by an over current if the AC drive added atthis time. This parameter enable the AC drive to output a direct current before running themotor that will produce a torque to forced motor stop and get a steady start-upcharacteristic.508 - 02 DC Brake Time during Stopping Factory Setting: 0.0Settings 0.00~60.00 Sec Unit: 0.01 This parameter determines the duration of time that the DC brake current will be applied tothe motor during stopping. Motor may be in rotation status after AC drive stops output and can’t in stop status accuracywhen motor is running with external force or itself inertia. After AC drive stops output, thisparameter could output a DC current to produce torque force motor to stop and make surethe motor has stopped accuracy.08 - 03 Start-point for DC Brake Factory Setting: 0.00Settings 0.00~120.00 Hz Unit: 0.01 This parameter determines the frequency when DC brake will begin during deceleration. If this parameter is set greater than 01-05 minimum frequency setting, it won’t decelerate to01-05 and enter DC brake status when AC drive brakes. Suitable DC brake start-upfrequency setting will get better brake characteristic.DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED 5-39
