Final Adjustments
3-22 Manual # 42-02-2P24
If the car does not leave a landing
• If the elevator is trying to level, it will not pick high speed and leave the landing until is
completes leveling.
• Check status of SAFL. Verify door locks are made.
• Verify Auxiliary Speed (F7, 153) not set to 0.0 FPM.
• Verify Acceleration and Start Jerk settings.
• If any of the inputs that open the door are active (Safety Edge On, Photo Eye On, etc.) or if
the UIO board car call terminal for the current floor (floor displayed in PI) is grounded the
car will not move.
Load Testing AC Drives
1. Add 100 or 200 pounds of test weights to the car.
2. Observe current draw as the car is accelerating.
3. Repeat until rated load is achieved, looking for:
• Overload drive errors, indicating that the drive is being pushed close to its limits and
may require:
• If requested acceleration rate is excessive, reduce acceleration rate. The lower the
acceleration rate, the lower the current demand.
• Adjust jerk for a more gradual transition from acceleration to high speed.
• Adjust drive gains.
• The motor may be underrated. Try reducing the motor speed setting slightly.
• Check for proper counterweighting. (With a balanced load, drive/motor current
should be the same in both up and down directions.)
• If needed, make a copy of the drive parameter table and write down all settings. Con-
tact MCE for assistance.
Trouble Slowing with a Full Load
If there is an issue with slowing a fully loaded car in the down travel direction, or if the AC drive
is tripping off with an over voltage fault displayed, it may mean that there is a problem with
regenerative braking or with the brake control module (if supplied).
Refer to the drive manufacturer manual. Generally:
• 230V drive will trip on over voltage if the DC bus Peak voltage reaches about 400 Volts or
if standard DC bus voltage reaches about 325 Volts.
• 460V drive will trip on over voltage if the DC bus Peak voltage reaches about 800 Volts or
if standard DC bus voltage reaches about 650 Volts.
1. With the drive in operating mode, check DC bus and DC bus Peak voltage displays while
the car is slowing with a full load in the down direction.
Danger
If you choose to actually measure the voltage across the drive power terminals, exercise
extreme care. These voltages are lethal.
