Hypernet CNC to control
module connection or a
discrete CNC to control
module connection.

Possible Causes
Gain settings for lifter are
causing unstable motion.
Possible mechanical
problem with the lifter.
Possible problem with the
encoder.
Possible damaged lifter
cable.
The CNC may not be using
the correct logic to operate
this input.
The CNC I/O cable may
be damaged.
There was a faulty input
(IHS Complete) or a fault
output (IHS_Sync) at the
CNC.
There was a faulty input
(IHS Complete) or a fault
output (IHS_Sync) at the
control module.
Corrective action
Check the Transfer Height setting in the Plasma
process screen.
Check the lifter cables for damage.
If this is a new installation, check the Gain settings
for the lifter. If it is a Hypertherm lifter, refer to the
instruction manual for proper settings.
In the diagnostic screen of the EDGE Pro or control
module, jog the motor up and down.
Check the lifter for binding.
Make sure position is changing and values are going
in the right direction (lower torch = positive direction.)
If a CNC is using the IHS_Sync signal, the IHS
Complete output needs to be used as well.
Check the Hold settings within the CNC.
Check the CNC I/O cable for damage.
Check the IHS_Sync output from the CNC to the
THC. Force on the output at the CNC and check the
IHS_Sync input at the control module.
Check the IHS Complete output. Jump out the IHS
Complete output and verify that the IHS Complete
input at the CNC turns on.
