GB - 64Start-up4.3 Start-up of a synchronous motor with speed encoder without gearboxLb.01: Input of passwordLb.03: Select the appropriate motor type (Lb.03=S GL/ 3: SSM closed loop gearless)Lb.05: Select the mode of setpoint settingLb.10: Decide, whether you want to assign other functions to the digital in-/outputs.Lb.18: If you want to know the energy losses on the braking resistor, enter the value of the brake resistorLd.02toLd.10: Enter the motor data according to the name plate.Ld.12: Possibly adjust torque limit, to protect the drive against overload during acceleration.Ld.14: If winding resistance (Ld.08) and winding inductance (Ld.09) are not known, they can be measured withLd.14.Ld.20: Possibly adjust torque load, to protect the UPS (uninterruptible power supply) against overload.LC.12: Enter the increments per revolution of the motor encoder.LC.16: Enter the system position value. If it is not known, it must be calibrated with LC.18=“1“ + start command.This procedure should be repeated three times.If the values of LC.16 should deviate more than 2500 increments, calibration by LC.15 is required.LF.01toLF.05: Enter the data for the elevator.LF.03: Set gear reduction ratio to „1“ .LF.20toLF.27: Setting of the corresponding speeds.LF.30toLF.36: Setting the value for the drive profile.LF.40: Set the brake release time. A time that is too short causes a starting jerk against the brake. A time that istoo long delays the start. Experience values: 0.3…0.8 s.LF.41: Set the brake apply time. A time that is too short causes a rolling back before the brake is completelyapplied. A time that is too long results in a dropout-delay of the main contactors. Experience values:0.3…0.7 s.Carry out following checks/optimizations during some test rides:• Rolling back upon releasing the brake or at stopping can be optimized by increasing LF.13 in steps of 500.• For fast plants it may be necessary to use the torque precontrol, to ensure a perfect load transfer.• Starting can be significant improved by LF.52/LF.53 at rucksack lifts.
