Condition Meaning/Possible causes of error
LED On Axis 1 and axis 2 are ready for operation.
(operating state) MCU acknowledges readiness (both SH1 LEDs are Off)
LED Off (error) The safety relay did not respond.
(Is 24 V power supply available at X73/3)?
RESET (+24 V) from unit bus?
Controller pulse inhibit (+15 V) from unit bus?
P5 (+5 V) does not exist?
LED On (error) MCU acknowledges error in readiness.
(X111/X112-SH1 pin 5a low)
LED usually off No controller enable for axis by MC.
With PLC module 9161, the iTNC sets the axis-specific
internal current and speed controller
(X111/X112 pin 4a high).
Speed and current controller are not active?
Clamping axis clamped?
No M function active for spindle?
