Troubleshooting
138
Below lists the HPV 600’s faults, alarms, and operator messages along with possible causes and
corrective actions.
Note:
•
fault
- a severe failure that will stop a drive if it has been running and prevent the drive from starting
as long as it is present. All faults require some type of action by the user to clear.
•
alarm
- only meant for annunciation. It will NOT stop the operation of the drive or prevent the drive
from operating.
•
operator message
- operator communications message. It will NOT stop the operation of the drive
or prevent the drive from operating.
Name
Description
Possible Causes & Corrective Action
A to D Fault
The Analog to Digital conversion on
the drive’s control board is not working
properly.
Drive Control PCB Failure
➲
Replace Drive Control board
Brake Alarm
(alarm
)
Dynamic brake resistor overcurrent.
Note: After the run command has been
dropped, this alarm becomes a Brake
IGBT fault.
Brake Resistor problem
➲
Braking Resistor is shorted.
Brk Hold Flt
The brake hold command and the
brake feedback did not match for the
time specified with Brake Hold Time
parameter.
Check Parameter Settings
➲
Check BRAKE HOLD SRC (C1) parameter
for the correct source of brake hold feedback
➲
Check BRAKE HOLD TIME (A1) parameter
for the correct brake hold time.
If nuisance fault, the fault can be disabled by
BRK HOLD FLT ENA (C1) parameter.
Brk IGBT Flt
Dynamic brake resistor overcurrent.
Brake Resistor problem
➲
Braking Resistor is shorted.
When this fault occurs while the elevator is in
motion, it will be declared as a brake fault alarm
until the run condition is removed. If the drive is
in regeneration an Overvolt Fault may occur
instead.
Brk Pick Flt
The brake pick command and the
brake feedback did not match for the
time specified with Brake Pick Time
parameter.
Check Parameter Settings and Mechanical
Brake Pick Signal Wiring
➲
Check the correct logic input is configured for
the correct TB1 terminal and set to MECH
BRK PICK (C2)
➲
Check wiring between the mechanical brake
and the terminal on TB1.
➲
Check BRAKE PICK SRC (C1) parameter for
the correct source of brake pick feedback
➲
Check BRAKE PICK TIME (A1) parameter for
the correct brake hold time.
If nuisance fault, the fault can be disabled by
BRK PICK FLT ENA (C1) parameter.
