REMARK
Refer to APPENDIX 1 for details on the minor error code, major error code and
servo error code storage registers.
(8) External stop input disable at start command (M3209+20n)
....................... Command signal
This signal is used to set the external stop signal input valid or invalid.
• ON .......... External stop input is set as invalid, and even axes which stop
input is turning on can be started.
• OFF .......... External stop input is set as valid, and axes which stop input is
turning on cannot be started.
POINT
When it stops an axis with the external stop input after it starts by turning on the
external stop input disable at start command (M3209+20n), switch the external stop
input from OFF
ON (if the external stop input is turning on at the starting, switch
it from ON
OFF ON).
(9) Feed current value update request command (M3212+20n)
....................... Command signal
This signal is used to set whether the feed current value will be cleared or not at
the starting in speed/position switching control.
• ON .......... The feed current value is updated from the starting.
The feed current value is not cleared at the starting.
• OFF .......... The feed current value is updated from the starting.
The feed current value is cleared at the starting.
POINT
When it starts by turning on the feed current value update request command
(M3212+20n), keep M3212+20n on until completion of the positioning control.
If M3212+20n is turned off on the way, the feed current value may not be reliable.
(10) Servo OFF command (M3215+20n) .................. Command signal
This command is used to execute the servo OFF state (free run state).
• M3215+20n: OFF ..... Servo ON

This command becomes invalid during positioning, and should therefore be
executed after completion of positioning.

Turn the power supply of the servo amplifier side off before touching a servomotor, such as
machine adjustment.
