MPI-C FOLLOWING ERROR
Description:
Commanded speed and speed feedback from the motor encoder have deviated by more than
the percentage of Following Error set through F7, parameter 189. The car performs an emergency stop,
dropping power to the motor and the brake. After stopping, the car will again attempt to run. If the error
persists, the car will be removed from service.
Troubleshooting
:
1. Check the encoder cable and connection.
2. Check to see what errors the drive is reporting.
3. Run the car on Inspection. Check commanded speed and speed feedback through the MPI-C diagnos-
tics screen. Please refer to “MPI-C Diagnostics” on page 4-84, addresses 16 and 18. For additional ver-
ification, use a hand tach to measure car speed. Adjust F7, 189 to 100% of contract speed to reduce
sensitivity. If commanded speed and actual speed track, the problem is likely to be inadequate F7, 189
percentage or F7 and drive settings related to motor speed, gear reduction, sheave diameter, roping,
etc. If commanded and actual speed deviate severely, the problem is likely to be with the encoder,
encoder connection, or in the drive (which should be reporting errors as well).
MPI-C INSPECTION OVERSPEED
Description:
The car has exceeded the speed calculated from 149 Contract Speed and 146 Inspection
Overspeed parameters.
Troubleshooting
:
1. Verify drive is set to SerSP.
2. Adjust drive gear ratio parameter LF.22.
3. Reset MPI board microprocessors.
4. If car is idle, check that the setting of F7 parameter 184 is correct.
MPI-C LANDING SYS A POSITION DEVIATION
Description:
MPI-C on the TC-MPI board has detected that the position reported by the ELGO, A position
sensor is not within limits when compared to the position synthesized feedback from the machine encoder.
The car will perform an emergency stop and remove itself from service.
Troubleshooting
:
1. Check appropriate F5 menu parameters (16 for microcontroller A/B and C) to determine if the speed
feedback for microcontroller C is significantly different from microcontroller A/B. If it is, modify the
hoist motor Speed parameter to change the speed seen by microcontroller C.
2. Check the integrity of the position sensor head and tape. Check that the sensor head is clean.
3. Check the CAN connection from the sensor head to the MC-LSI board.
4. Replace the position system sensor head. Refer to the installation section of this manual and follow all
installation steps and recommendations carefully.
MPI-C LANDING SYS B POSITION DEVIATION
Description:
MPI-C on the TC-MPI board has detected that the position reported by the ELGO, B position
sensor is not within limits when compared to the position synthesized feedback from the machine encoder.
The car will perform an emergency stop and remove itself from service.
Troubleshooting
:
1. Check appropriate F5 menu parameters (16 for microcontroller A/B and C) to determine if the speed
feedback for microcontroller C is significantly different from microcontroller A/B. If it is, modify the
hoist motor Speed parameter to change the speed seen by microcontroller C.
2. Check the integrity of the position sensor head and tape. Check that the sensor head is clean.
3. Check the CAN connection from the sensor head to the MC-LSI board.
4. Replace the position system sensor head. Refer to the installation section of this manual and follow all
installation steps and recommendations carefully.
MPI-C LEVELING TIMER EXCEEDED
Description:
The car is traveling at leveling speed for an unusually long period of time. Direction will be
dropped and a correction run will be performed to the next available landing.
Troubleshooting
:
1. Verify eligibility is properly reflected in the F7 menu in regards to floor heights.
