Start-Up Of An Asynchronous Motor With Speed Encoder And Gearbox - KEB Combivert F5 Instruction Manual

Start-up
4.2

Start-up of an asynchronous motor with speed encoder and gearbox

Lb.03: Selection of the appropriate motor type (Lb.03= AG/ 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.11: If necessary, limit the maximum torque for normal operation.
Ld.20: Possible limitation of the maximum torque for UPS operation, to protect the UPS (uninterruptible power
supple) against overload..
LC.12: Adjust the increments per revolution of the motor encoder.
LF.01
to
LF.05: Adjust the data of the elevator.
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 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 value.
Carry out following checks/optimizations during some test rides:
• Is the desired travel direction (up/down) maintained ?
• Compare setpoint speed LI.03 with actual speed LI.04. The sign of both speed displays in the same travel di-
rection must be the same (positive is not displayed). If the sign is not equal, an encoder track change must be
made with LC.13. In addition to that the travel direction can also be changed:
• Optimization of the load transfer by increasing LF.13 in steps of 500, if the drive turns away too much on relea-
sing the brake.
