Error	Message	Cause & Effect	Action
401	PLC failure detected	CPU10 stopped with PLC failure bit set. Job cancelled.	Check PLC fibers and PLC logic power.
402	PLC Online	PLC has returned on line
404	Spindle drive fault detected	CPU10 stopped with spindle drive fault bit set. Job cancelled.	Check inverter for fault or reset spindle contactor OCR, then cycle EMERGENCY STOP
405	Lubricant level low	CPU10 stopped with low lube fault bit set. Current job will finish but nothing will work after that.	Add lube or check low lube switch wiring then cycle EMERGENCY STOP
406	Emergency Stop detected	CPU10 stopped with no fault bits set. Job cancelled.	Release Estop
407	X+ limit (#1) tripped	CPU10 stopped with limit switch tripped. Job cancelled.	Clear limit switch
408	Programmed action timer expired	M103 time expired before M104 encountered. Job cancelled.	Find out why timer expired before specified action was completed.
409	_ axis lag	Lag Distance (Allowable Following Error) is detected on any axis for more than 1.5 seconds. Where: Lag Distance= Feedrate inch/min --------------------------- + .0005 inch/int 240,000 ints/min (Allowable Following Error) All axis motion is stopped and the CNC program is aborted. The probable causes of this error are: 1. The machine is doing a very heavy cut. 2. The maximum rates or the acceleration values for the motors are set too high. 3.The motors are undersized for the application	1. If the problem is occasional heavy cuts, slowing down the cutting feedrate can solve the problem. 2. If the problem only occurs on high speed moves then either the maximum speed or the acceleration is set too high. Lower the values in the Motor Setup screen or run Autotune again to determine new values. 3. If there are persistent lag errors in normal operations, this indicates that the motors are too weak to handle the required loads. Increase the gear ratios or get more powerful motors.

410	_ axis position error	A position error > .25 inches is detected on any axis. All axis motion is stopped, power to the motors is released (all servo drive commands cease) and the CNC program is aborted. The probable causes of this error are: 1. The motor is wired up backwards. 2. Noise is getting into the system via the motor cables (the line integrity has been violated). 3. An encoder error occurred.	1. Try to slow jog the motor and watch the DRO position. If the position on the DRO goes opposite the direction indicated on the jog button, then the motor is wired up backwards. Change the motor wiring. 2. Check the motor cabling paying particular attention to the ground connections. Replace the cable if it is damaged or repair the motor connections. 3. Jog the motor awhile, at the maximum rate, using the fast jog buttons. (Check the fast jog rate in the motor jog parameters screen to make sure it is set equal to the maximum motor rate.) If the motor seems to jump around rather than accelerate and decelerate smoothly then you are probably fighting an encoder error. Swap the motor with one from another axis and see if the error follows the motor. If it stays with the axis, replace the CPU. If it follows the motor, replace the motor cable. If the problem still persists, replace the motor and encoder.
411	_ axis full power without motion	90% Power (PID Output > 115) is applied to any axis and no motion >.0005 inches is detected, for more than the time specified in parameter 61 (default .5 sec.). All axis motion is stopped and the CNC program is aborted. The probable causes of this error are: 1. One of the axes is against a physical stop. 2. The servo drive has shutdown due to a limit switch input. 3. The Z home switch is the same as the Z + limit switch.	1. If the axis has run into a physical stop, use the slow jog mode to move the axis away from the stop. Determine and set software travel limits to stop machine before in runs into the hard stops. 2. If the axis is not on a physical stop, check for a tripped limit switch. If it is then the software is commanding a move into the switch but the hardware is shutting the move down. Go to the motor setup screen and enter the limit switch input number if applicable. 3. Make sure the switch input is not unstable or noisy. If it is then replace the switch. If the problem persists it may be necessary to create separate home and limit switch inputs. Use slow jog to move opposite the direction causing the error and clear all limit switches. Jog toward the direction causing the error, if no motion occurs then a servo drive failure is indicated.
