Cause: Plasma Source Amperage Set Too Low
Probability How-To Steps Need More?
High
If you are using the AutoFS Material Picker, make sure that you have your
plasma source cut current set to match the value suggested on the main
page of PathPilot.
If you are using the Hypertherm control kit to allow PathPilot to control cut
current and air pressure, verify that the adapter is connected to the
controller's USB port and the RS-485 cable is plugged in to the back of the
plasma source.
9.5 SERVO DRIVES
9.5.1 Servos Fault on Fast Direction Changes
Cause: Power Supply not Connected to Backfeed Clamp
Probability How-To Steps Need More?
High Check for loose wires between the power supply and backfeed clamp (PN
39102 ).
l
Power off the main breaker.
l
Measure the continuity between the V+ terminal of the power supply and
the + terminal on the backfeed clamp (follow wire 207 ).
l
Perform the same check for the V- terminal of the power supply to the -
terminal of the backfeed clamp (wire 208 ).
l
Power on the main breaker, release the E-Stop button and press the blue
Reset button.
l
You should see a green power LED on the power supply and an orange ON
LED on the backfeed clamp if they are connected correctly.
The servos used in the 1300PL feed a
significant amount of energy back into
the power supply when braking. This
energy is dissipated by the backfeed
clamp.
