Troubleshooting
135
Name
Description
Possible Causes & Corrective Action
Drive Ovrload
[F08]
The drive has exceeded the drive
overload curve.
Excessive Field Weakening
Decrease FLUX WKN FACTOR (A1)
parameter
Decrease both MTR TORQUE LIMIT
(A1) and REGEN TORQ LIMIT (A1)
parameters
Watch for the Torque Limit LED (see
Table 23 on page 130), if lit 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,
see Motor Parameter
Calculations.
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
Check encoder coupling: align or replace
Encoder failure (replace encoder)
Check encoder count parameter
ENCODER PULSES (A1)
Motor Problem
Check for motor failure
Drive Sizing
Verify drive sizing. May need a larger
capacity HPV 900 Series 2
Drive Temp
Alarm
(alarm)
[F75]
The heatsink on the drive has
exceeded 85
C.
Excessive Heat
Reduce Ambient Temperature
Clean heat sink
Check for cooling fan failure
