Troubleshooting
148
Name
Description
Possible Causes & Corrective Action
Srl Timeout
(Fault)
[F45]
Srl Timeout
(Alarm)
[F81]
The drive is being operated by serial
communications and one of the
following has occurred:
Communication time-out
– if the
serial run bit is set and the drive
does not receive a run-time
message for 40 msec
Bad message checksum
– drive
has detected fifteen consecutive
bad message checksums
Bad Serial Connection
Remove and re-seat the serial cable
Check car controller serial driver board
Check the serial cable connected to the
drive
Also, the drive’s control board may need
to be replaced.
Check Parameter Setting
If not using serial communications,
check SERIAL MODE (C1) = none
Start Time High
(alarm)
The drive saw movement during ARB
mode before ARB START TIME (A1)
is active
Check Parameter Setting
Lower ARB START TIME (A1) to occur
before the brake lifts
Possible noise issue
Verify grounding shield of encoder cable
is directly wired to solid ground
Stall Fault
(open loop)
[F56]
Generated when the motor current
goes at or above a percentage
(defined by STALL TEST LVL) for
defined amount of time (defined by
STALL FAULT TIME).
Check Parameter Settings
Check STALL TEST LVL
(A1)
parameter for the correct percentage of
motor current
Check CONTACT FLT TIME
(A1)
parameter for the correct time
If nuisance fault, the fault can be
disabled by STALL TEST ENA (C1)
parameter (set to disabled)
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
Motor Problem
Check for motor failure
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
Tach Loss Flt
[F68]
See ENCODER FLT
See ENCODER FLT
Tq Lim
2Hi 4cube
[F46]
The torque limits (based on the
defined motor) exceed the cube’s
capacity
Check Parameters Settings
Verify motor nameplate values are
entered correctly in the A5 sub-menu
Decrease both MTR TORQUE LIMIT
(A1) and REGEN TORQ LIMIT (A1)
parameters
Drive Sizing
Verify drive sizing. May need a larger
capacity HPV 900 S2
