Operation not completed
/ During operation
(Not always, but may happen
occasionally)
Alarm for “Step data ALM2
/code: 1-051” is generated.
↓
<Procedure of restart>
Input the “reset” signal.
1) Command invalid
(unregistered) step data.
Check if the step data is valid
(registered).
2) Different input signal to the
expected step number is
inputted to the controller,
because of a too short an
interval between the input
signal of the “IN*” and the
“Drive” or inputting the signals
at the same time.
Add an interval of 15ms (the
recommendation is 30ms) or more
between the input signals.
/
See “Operating procedure input
and output signals for each
operation type” on P.30
3) Different input signal to the
expected step number is
inputted to the controller,
because the input signal time
was too short.
Maintain the state of the input
signal for 15ms (the
recommendation is 30ms) or
more .

See “Operating procedure input
and output signals for each
operation type” on P.30
4) Different input signal to the
expected step number is
inputted to the controller,
caused by PLC or other device.
Check that the step number is
inputted correctly for the required
motion.
- Operation completed by
unexpected motion.
- No alarm
