The THC controls the
lifter speed between
5% and 100% of the
maximum speed value
stored in the ArcGlide Axis
setup screen. If a speed
greater than 120% of the
maximum value is detected
during operation, motion
is stopped and an error is
posted.
Excess speed was
detected during operation.
Speed Gain could be set
too high or improper values
are being used for the
Encoder Counts per Inch
parameter.
There could also be a
problem with the motor’s
encoder, faulty wiring in
the lifter cable, or a faulty
motor drive in the control
module.
If this is a newly installed system, check these setup
parameters:
• Max Speed
• Speed Gain
• Encoder Counts per Inch
Power down the control module and power back up
and check operation again.
If a Hypertherm lifter problem persists, try resetting
the control module. Manually jog the lifter down while
watching the LCD on the HMI or control module and
verify that the position being displayed increases as
the torch moves downward.
If the lifter is not a Hypertherm lifter and the
installation is new, change the encoder wiring to the
control module.
If this is an existing system that was previously
working, check the cable connections to the motor
encoder. Verify that the set screws for the mechanical
coupling between the motor and lifter slide are
tightened properly.
If all of the above are good, call Hypertherm Technical
Service. There could be a faulty motor encoder or a
problem with the motor amplifier.
3
While the lifter is moving
toward home position, the
motor control is reading
negative motion from the
lifter motor but the HOME
switch input or stall force
was not sensed after a
reasonable length of time.
The slide mechanics may
be malfunctioning.
Verify that the lifter moves when the motor is
operating.
Check the coupling between the motor and the ball-
screw and verify that the set screws are tightened
properly.
Check the lifter cables for damage.
