3 POSITIONING DEDICATED SIGNALS
(2) TEST mode ON flag (SM501) ..................................... Status signal
(a) This flag is used as judgement of during the test mode or not using
MT Developer2
Use it for an interlock, etc. at the starting of the servo program using the
Motion SFC program.
• OFF ........... Except the test mode
• ON ............. During the test mode
(b) If the test mode is not executed in the test mode request from
MT Developer2, the TEST mode request error flag (SM510) turns on.
(3) External forced stop input flag (SM502) ...................... Status signal
This flag is used to check the external forced stop input signal ON/OFF.
• OFF ......... External forced stop input ON
• ON ........... External forced stop input OFF
POINTS
(1) If the forced stop signal is input during positioning, the operation is as follows.
• When using Q173DSCPU/Q172DSCPU
The feed current value becomes the same value as the real current value.
• When using Q173DCPU(-S1)/Q172DCPU(-S1)
The feed current value is advanced within the rapid stop deceleration time set
in the parameter block.
At the same time, the servo OFF state is established because the all axes servo
ON command (M2042) turns off.
When the rapid stop deceleration time has elapsed after input of the forced stop
signal, the feed current value returns to the value at the point when the
emergency stop was initiated.
(2) If the forced stop is cancelled while the rapid stop deceleration time isn't
progressing, an overspeed error or error excessive error may occur.
(4) Digital oscilloscope executing flag (SM503) ................ Status signal
This flag is used to check the state of execution for the digital oscilloscope.
• OFF ......... Digital oscilloscope has stopped.
• ON ........... Digital oscilloscope is executing.
(5) External forced stop input ON latch flag (SM506)
This flag turns on when an external forced stop input is detected.
After that, it remains ON even if the external forced stop input is cancelled.
Reset the external forced stop input ON latch flag using the Motion SFC
program.
• OFF ......... External forced stop input is not detected.
• ON ........... External forced stop input is detected.
