Relevel Operation
On Inspection, move the car to the bottom landing onto leveling. Take the car off Inspection
and observe that it re-levels into the landing. If the car attempts to re-level but cannot:
1. If the car attempts to relevel but cannot:
• Adjust Leveling speed parameter F7:158 to get the car to move.
• Check that the car is not opening the down final limit.
2. If a fault code is displayed, troubleshoot and correct the fault.
3. Verify that the position indicator matches the car position.
4. Verify that the brake has been set as described in Section 2 to hold 125% of load,
Brake to 125% of Full Load on page 2-83
.
Brake Coordination
1. Adjust speed pick delay parameter F7:134 so that the brake is fully picked just as the
motor first spins. The goal is to avoid spinning the motor before the brake is picked but
not to introduce so much delay that rollback occurs.
2. KEB, TorqMAX: Refer to the Torqmax drive manual for information relating to speed
pick delay interaction with pre-torque parameters.
3. Magnetek: Refer to Rollback Gain in the Magnetek HPV AC Drive Technical Manual.
Run Tests
Register calls to all the landings in turn and observe that the car stops properly at the requested
landing. As drive adjustments are made to tune performance, parameters on the controller F7
menu may need readjustment: Profile Advance, Leveling Distance, Leveling Dead Zone, Stan-
dard Slew Slope, Standard Stop Jerk, etc.
Adjustment Problems
Speed Changes Felt Excessively in Car
During high speed, if the speed change
from accel to high speed or from high speed to decel can be felt excessively in the car:
• KEB: Decrease parameter A.LF.33 Ki speed offset accel and/or d.LF.33 Ki speed offset
decel and d.LF.32 in steps of 100 to achieve smoother transitions. This may also be due to
inaccurate drive adjustment,
Please refer to “Speed and Acceleration Control” on page 2-
.
• MAGNETEK: Consider Estimation of System Inertia, A0/A1 Response, A0/A1 Inner Loop
Xover, A0/A1 Gain Reduce Mult, and A1/A0 Gain Chng Level.
Loss of Control During Acceleration
Acceleration rate should be at least as great
as deceleration rate but should not exceed deceleration rate by too much. Excessive acceleration
rates may cause drive circuits to saturate and effectively lose acceleration control.
