GK600-CF Dedicated VFD For Hoist And Crane
GK600 Series Dedicated AC Motor Drives for Hoist and Canes GK600-CFUser ManualFunction DescriptionGK600-CF Series mainly provides upstroke and downstroke contracting brake for cranes. Different contracting brake logic functions can be set for downstroke contracting brake parameters. The E0 group parameters are consistent with GK600 General Purpose AC Motor Drives User Manual,Website:, describing upstroke contracting brake functions. The F4 group is added as downstroke contracting brake parameters.This supplementary user manual is required to be used together with GK600 Series General Purpose AC Motor Drives User Manual.The F4 group of downstroke contracting brake parameters is added.Hardware ModificationNoneList of ParametersParam.DesignationScopeFactory DefaultAttr.E0-05Contracting brake control0: Disabled1: Enabled0×E0-06Contracting brake release frequency0.00Hz~10.00Hz2.50△E0-07Contracting brake release current0.0%~200.0%120.0△E0-08Accel delay time after contracting brake release0.0s~10.0s1.0△E0-09Contracting brake frequency0.00Hz~10.00Hz2.00△E0-10Contracting brake suction waiting time0.0s~10.0s0.0△E0-11Contracting brake suction holding time0.0s~10.0s1.0△Downstroke contracting brake parametersF4-00Downstroke contracting brake enabled0: Prohibited1: Enabled0×F4-01Downstroke direction0: Forward downstroke1: Reverse downstroke0△F4-02Downstroke contracting brake release frequency0.00Hz~10.00Hz2.50△F4-03Downstroke contracting brake release current0.0%~200.0%(Compared to the rated current of motor)120.0△F4-04Accel delay time after downstroke contracting brake release0.0s~10.0s1.0△F4-05Downstroke contracting brake frequency0.00Hz~10.00Hz2.00△F4-06Downstroke contracting brake suction waiting time0.0s~10.0s0.0△F4-07Downstroke contracting brake suction holding time0.0s~10.0s1.0△F4-08Downstroke contracting brake release starting mode0: Started from starting frequency1: DC brake and then started 0△F4-09confirmation mode of contracting brake release0: Internal condition1: Confirmed by external terminal0△F4-10Current limit enabled0: Invalid according to current limit output frequency function1: Valid according to current limit output frequency function0△F4-11Current limits running frequency upper limit of threshold below0~600.00Hz50.00△F4-12Current limits running frequency upper limit of threshold above0~600.00Hz45.00△F4-13Current limit threshold percentage (Compared to the rated current of motor)0~200.0%30.0%×F4-14Current limit hysteresis loop percentage (Compared to the rated current of motor)0~20.0%5.0%×F4-15Downstroke contracting brake halt mode0: Decided by b1-131: DC braking stop0×F4-16Downstroke stop DC braking current0~200.0%100.0△F4-17Downstroke crease line deceleration time switchover enabled0: Disabled1: Enabled0△F4-18Switchover frequency of downstroke crease line deceleration time0~10.00Hz0△F4-19Downstroke contracting brake release waiting time0~10.0s0△F4-20downstroke loosing brake DC braking current0~200.0%0△F4-21SP1 fault masking0: Not masking fault1: Mask SP1 fault0△F4-22Upstroke/downstroke switchover repeatedly to check whether not contracting brake, and then loose brake0: Need first contract brake and then loose brake1: Need first contract brake and then loose brake after entering the contracting brake area2: No need; right through0△F4-23Accel/decel time switchover enabled at low frequency0: Prohibited accel/decel time switchover at low frequency1: Enabled accel/decel time switchover at low frequency0△F4-24Switch over frequency at low frequency0.00Hz~10.00Hz0.00△Detailed Explanation of FunctionsE0 group parameters: Please refer to GK600 General Purpose AC Motor Drives User Manual for upstroke contracting brake functions.F4 group:F4 -00Downstroke contracting brake enabledScope: 0~1Factory Default: 00: Prohibited
