Troubleshooting
144
Name
Description
Possible Causes & Corrective Action
HW/SW
Mismatch
Software not compatible with hardware
Incorrect Software
➲
HPV 900 software installed in a HPV 600
➲
Replace software with correct version
Motor id Flt
Motor parameters checksum is invalid.
Parameters Corrupted
Mtr data Flt
➲
Check parameters and reset
➲
If re-occurs, replace Drive Control board
Mspd Tmr Flt
[closed-loop]
This fault is declared if at least two
MLT-SPD TO DLY x (C1) parameters
are defined to the same multi-step
speed command.
Check Parameters Settings:
➲
Check MLT-SPD TO DLY 1 (C1) parameter
for setting
➲
Check MLT-SPD TO DLY 2 (C1) parameter
for setting
➲
Check MLT-SPD TO DLY 3 (C1) parameter
for setting
➲
Check MLT-SPD TO DLY 4 (C1) parameter
for setting
Mtr Overload
(alarm)
The motor had exceeded the user
defined motor overload curve.
Verify Overload Curve Parameters
➲
Check both OVLD START LEVEL (A5) and
OVLD TIME OUT (A5) parameters
.
Excessive Field Weakening
➲
Decrease FLUX WKN FACTOR (A1)
parameter
➲
Decrease both MTR TORQUE LIMIT (A1)
and REGEN TORQ LIMIT (A1) parameters
➲
Watch for the “
Hit Torque Limit” alarm
message
, if message appears the torque
limits or the flux weakening factor parameters
were decreased too much.
Accurate Motor Parameters
➲
Verify motor nameplate values are entered
correctly
➲
Complete Adaptive Tune and Inertia
procedure
.
➲
As a last step, calculate motor parameters
from motor’s equivalent circuit.
Excessive Current Draw
➲
Decrease accel/decel rate
➲
Is elevator car being held in position? (i.e.
mechanical brake not releasing)
➲
Mechanical brake may not have properly
released
Encoder Problem
(closed-loop only)
➲
Check encoder coupling: align or replace
➲
Encoder failure (replace encoder)
➲
Check encoder count parameter ENCODER
PULSES (A1)
Motor Problem
➲
Check for motor failure
