M800/M80/E80/C80 Series Alarm/Parameter Manual
1 Operation Errors (M)
M01
PLC interruption impossible
Details
After the cycle start, the "PLC interrupt" signal was turned ON during buffer correction, program restart, arbi-
trary reverse run, tool retract and return, high-speed high-accuracy control II, NURBS interpolation or single
block stop at the middle point of G28/G29/G30.
Remedy
By turning OFF the "PLC interrupt" signal, or by resetting the NC the error can be cancelled.
M01
Restart posn return disabled
Details
Restart position return was attempted in a mode where the return is disabled.
Remedy
Correct the program restart position.
M01
Zero point return interruption
Details
Compound type fixed cycle program was interrupted with manual zero point return, and cycle start was carried
out without carrying out reset.
Remedy
Cancel the program execution by reset.
M01
Excessive no. of reverse block
Details
During the reverse run in arbitrary reverse run, any one of the part systems reverse-ran for 20 blocks.
Remedy
This error is cancelled by forward run.
M01
Illegal mode in prg check mode
Details
Any of the following modes has been turned ON during the manual arbitrary reverse run mode.
MDI interruption mode
Manual/automatic simultaneous valid (MAE1 to 8)
Arbitrary feed mode (PTP)
Arbitrary reverse control mode (RVMD)
Manual speed command enabled
High-speed simple program check mode (SMLK)
Remedy
The error can be cancelled by turning OFF the error-causing mode.
M01
Too many active axes per sys
Details
High-accuracy control has been executed in a part system which has 9 or more enabled control axes, except
for a slave or synchronous axis.
Remedy
Reduce the number of enabled control axes (except for a slave axis and synchronous axis) of the part sys-
tem to 8 or less through synchronous control, control axis synchronization across part systems, or mixed
control before executing high-accuracy control.
M01
Pre-intrpl variable accel err
Details
The parameter "#12060 VblAccPreInt" (Variable-acceleration pre-interpolation acceleration/deceleration
ON) is set to "1" and the parameter "#8090 SSS ON" is set to "0".
Remedy
To enable the variable acceleration pre-interpolation acceleration/deceleration, set the parameter "#8090
SSS ON" to "1".
To disable the variable acceleration pre-interpolation acceleration/deceleration, set the parameter "#12060
VblAccPreInt" to "0".
