Alarm And message
Number Message Contents
PS0181 ZERO RETURN NOT FINISHED A move instruction was issued to an axis in which the zero
return instruction was instructed once after the power was
turned ON.
Execute operation after zero return by manual operation or
the G28 code.
This alarm can be suppressed for the machine-locked axis
by setting parameter No. 1200#6 is set to "1".
PS0194 ZERO RETURN END NOT ON REF The axis specified in automatic zero return was not at the
correct zero point when positioning was completed.
Perform zero return from a point whose distance from the
zero return start position to the zero point is 2 or more
revolutions of the motor.
Other probable causes are:
- The positional deviation after triggering the deceleration
dog is less than 128.
- Insufficient voltage or malfunctioning pulse coder.
PS0200 PULSCODER INVALID ZERO
RETURN
The grid position could not be calculated during grid
reference position return using the grid system as the
one-revolution signal was not received before leaving the
deceleration dog.
This alarm is also generated when the tool does not reach a
feedrate that exceeds the servo error amount preset to
parameter No. 1841 before the deceleration limit switch is
left (deceleration signal *DEC returns to "1").
