3 POSITIONING DEDICATED SIGNALS
(6) Amplifier-less operation status flag (SM508) ............... Status signal
This flag is used to check the state of amplifier-less operation.
• OFF ......... During normal operation
• ON ........... During amplifier-less operation
(7) TEST mode request error flag (SM510) ...................... Status signal
(a) This flag turns on when the test mode is not executed in the test mode
request using MT Developer2.
(b) When SM510 turns on, the error contents are stored in the test mode
request error information (SD510, SD511).
(8) Motion CPU WDT error flag (SM512) .......................... Status signal
This flag turns on when a WDT error (watchdog timer error) is detected of the
Motion CPU self-diagnosis function.
When the Motion CPU detects a WDT error, it executes an immediate stop
without deceleration of the operating axes.
If the Motion CPU WDT error flag has turn on, reset the Multiple CPU system.
If SM512 remains on after resetting, there is a fault at the Motion CPU side.
The error cause is stored in the "Motion CPU WDT error cause (SD512)".
(Refer to Section 3.5.)
(9) Manual pulse generator axis setting error flag (SM513)
(a) This flag is use as judgement of normal or abnormal setting of the manual
pulse generator axis No. setting registers (D714 to D719).
• OFF ........... D714 to D719 is normal
• ON ............. D714 to D719 is abnormal
(b) This flag turns ON by turning ON the manual pulse generator enable flag
(M2051 to M2053) with the manual pulse generator axis P1 to P3 unused
after setting the manual pulse generator interface module (Q173DPX) in the
system setting.
(c) When SM513 turns on, the error contents are stored in the manual pulse
generator axis setting error information (SD513 to SD515).
(10) Servo program setting error flag (SM516) ................. Status signal
This flag is used as judgement of normal or abnormal for the servo program
positioning data.
• OFF ........... Normal
• ON ............ Abnormal
................................ Status signal
