11.6.3 Signals
11.6.3.1 Details on signals
Orientation command signal
ORCMA <G070#6>
[Classification] Input signal
[Function] This signal specifies spindle orientation.
When this signal is set to 1, the spindle immediately decelerates
during rotation and stops at a fixed position.
Be sure to set the signal to 0 before power-on.
Emergency stop signal
*ESPA <G071#1>
[Classification] Input signal
[Function] This signal specifies an emergency stop.
When the signal is set to 1, the spindle motor and spindle amplifier
module become ready to operate.
When the signal is set to 0, the spindle motor immediately decelerates
and then stops.
By monitoring the orientation completion signal (ORARA), set the
signal to 0 if there is a deviation from the stop position.
Since the spindle motor becomes ready to rotate when the signal is set
to 1, the spindle motor immediately rotates upon receiving the rotation
command. Therefore, immediately after setting this signal to 0, reset
the command signals (velocity command, forward command, and
reverse command) for the spindle amplifier module.
Power interruption signal
MPOFA <G073#2>
[Classification] Input signal
[Function] This signal turns off the excitation of the motor.
By setting the signal to 1, the excitation of the spindle motor can be
turned off to enable free running.
By monitoring the orientation completion signal (ORARA), set the
signal to 1 if there is a deviation from the stop position.
The excitation of the motor can be turned on again after the motor
stops (zero speed signal SSTA = 1). Even if this signal is set to 0,
excitation cannot be turned on while the motor is rotating (SSTA = 0).
After turning off the excitation of the motor, reset the command
signals (velocity command, forward command, and reverse command)
for the spindle amplifier module.
