(4) External emergency stop input flag (M9076)
..........................................................................Signal sent from PCPU to SCPU
This flag status indicates whether the external emergency stop input to the
power module's EMG terminal is ON or OFF.
• OFF .............. External emergency stop input is ON.
• ON ................External emergency stop input is OFF.
(5) Manual Pulse Generator Axis Setting Error Flag (M9077)
..........................................................................Signal sent from PCPU to SCPU
(a) This flag indicates whether the setting designated at the manual pulse
generator axis setting register (D714 to D719) is normal or abnormal.
• OFF................... All D714 to D719 settings are normal.
• ON .................... At least one D714 to D719 setting is abnormal.
(b) When M9077 switches ON, the error content is stored at the manual pulse
generator axis setting error register (D9187).
(6) TEST Mode Request Error Flag (M9078).........Signal sent from PCPU to SCPU
(a) This flag switches ON if the TEST mode is not established in response to a
TEST mode request from a peripheral device.
(b) When M9078 switches ON, the error content is stored at the manual pulse
generator axis setting error register (D9188).
(7) Servo Program Setting Error Flag (M9079) ......Signal sent from PCPU to SCPU
This flag status indicates whether the positioning data at the servo program
designated by the SVST instruction is normal or abnormal.
• OFF ..............Normal
• ON ................Abnormal
The content of a servo program error is stored at D9189 and D9190.
