Start-Up; Start-Up Of An Asynchronous Motor Without Speed Encoder With Gearbox - KEB Combivert F5 Instruction Manual

Start-up

4. Start-up
Adjust the parameters in ascending order, because by doing so partial pre-adjustments of the unit are initiated.
Start with the basic settings (Lb-parameter). Store the adjusted data by pressing the „Enter"-key.

Start-up of an asynchronous motor without speed encoder with gearbox

The following procedure is recommended for the start-up of the COMBIVERT F5 Lift with a gearbox-fitted asyn-
chronous motor:
Lb.03: Selection of the appropriate motor type (Lb.03= A G/ 0:ASM closed loop geared)
Lb.05: Select the mode of setpoint setting
Ld.01
to
Ld.06: Enter the motor data according to the name plate.
Ld.07: Enter or calibrate winding resistance.
LF.01
to
LF.05: Adjust the data of the elevator.
LF.10 set to 0 = open-loop operation
LF.20
to
LF.27: Adjustment of the corresponding speeds.
LF.30
to
LF.36: Adjustment of the drive profile.
LF.40: Adjustment of the brake release time. A time that is too short causes a starting jerk against the brake. A
time that is too long causes the rolling back after the brake is released. Experience values: 0.2...0.5 s.
LF.41: Adjustment of the brake apply time. A time that is too short causes a rolling back before the brake is
completely applied. A time that is too short causes a rolling back before the brake is completely applied.
A time that is too long results in a dropout-delay of the main contactors. Experience values: 0.3...0.7 s.
LF.49: If the motor temperature shall be monitored, enter the corresponding values.
Carry out following checks/optimizations during some test rides:
• Load-dependent driving can be optimized by lowering the rated motor speed in steps of 10 rpm.
• Measure the motor speed during an inspection ride with a hand-held tacho. It should nearly be the same speed
at „Empty-up" and „Empty-down".
• Deviations within the range of 5...10 rpm are normal.
• The rolling back at releasing the brake or at stopping can be optimized by increasing LF.16 in steps of 0.5%.
