6. APPLICATION FUNCTIONS
POINT
• For communication methods other than SSCNET /H, a mark detection setting
error (operation alarm 3B, detail No.01) occurs.
• When a servo amplifier that does not support mark detection is used, a mark
detection setting error (operation alarm 3B, detail No.02) occurs.
• Check that the user program does not omit any detections to avoid cases
where mark detection signals are not properly detected, and communication
errors occurrences etc.
• In the following cases, depending on the specifications of the servo amplifier,
the correct positioning data may not be got.
1) The ON/OFF width of mark detection signals is shorter than the control
cycle of 0.88ms.
2) Servo alarm has occurred.
• When an input other than driver input is set to sensor input method
(parameter No.0219), and general input setting is set to "Used" for general
input/output option (parameter No.0213), the current status of mark detection
signals can be checked with servo amplifier general input.
• When driver input is set to sensor input method (parameter No.0219), the
current status of mark detection signals can be checked with sensors
(LSP/LSN/DOG).
