DRIVE ERROR Occurs when the VSD PCBA
detects too low or too high of
a voltage on the DC drive bus.
Verify input line voltage is within
specifications. Error indicates voltage is too
low or high.
Ensure all
cables from the
configuration plate
to the VSD PCBA
are connected.
Cable going to P20
on VSD PCBA is
most likely to cause
problem.
Replace VSD
PCBA.
Replace Configuration
Plate.
DRIVE PWR ERROR
Early versions of
software displayed
this error as “ABS
ERROR” or “POWER
LOSS ERROR”
Can occur during program
operation. Treadmill goes to
idle and stops quickly. This
Error can denote any of the
following:
1 - The DC bus that powers the
walkbelt is too low or high.
2 - The thermal switch on the
walkbelt motor is open due to
the motor overheating.
3 - The circuitry that measures
the walkbelt motor current has
failed.
Verify input line voltage is within
specifications. Error indicates voltage is too
low or high.
Let walkbelt motor
cool down and
cycle power. Motor
thermal switch may
open due to worn
belt and deck.
Ensure all
cables from the
configuration plate
to the VSD PCBA
are connected.
Cable going to
P20 on VSD PCBA
is most likely to
cause problem.
Replace VSD PCBA.
If problem persists
replace Configuration
Plate.
DRV RESET The processor on the VSD
PCBA cannot communicate
with the motor control IC on
the VSD PCBA.
Ensure all cables from the configuration plate
to the VSD PCBA are connected. Cable going
to P20 on VSD PCBA is most likely to cause
problem.
Replace VSD
PCBA.
GRD LIMIT ERROR
Unit must be reconfigured as a
TreadClimber.
Press [CLEAR].
Go to Change Machine Mode (Speed
Increase, 8, Enter, Enter), then scroll to
“TreadClimber” using the Speed Increase and
Speed Decrease keys.
