13.3.2 Motion Error Details and Corrections
13-28
(9) Excessive Speed (IL
04, bit 8)
(10) Excessively Following Error (IL
04, bit 9)
The above check is not per
formed if the Deviation Abnormal Detection Value (OL
22) is set to 0.
Detection Timing
• Enabled when the electronic gear is used and detected when positioning is executed.
Processing when Alarm Occurs
• The move command is not executed.
• The Command Execution End with Error bit in the Motion Command Status (IW
09, bit 3) will
turn ON.
Error and Cause
• The limit to the moving amount that can be distributed each scan has been exceeded.
Correction
• Check the speed reference and moving amount for the axis of the positioning that is being executed.
Detection Timing
• Detected during positioning (commands for positioning, external positioning, STEP operation, etc.).
• Detected during phase control commands.
Processing when Alarm Occurs
• The move command is not executed.
• The Command Execution End with Error bit in the Motion Command Status (IW
09, bit 3) will
turn ON.
Error and Cause
• The position loop gain and speed loop gain are not set suitably, creating poor response.
• The Deviation Abnormal Detection Value (OL
22) is too small.
• The capacity of the motor is insufficient for the machine load.
• SERVOPACK failure.
Correction
• Check the SERVOPACK gain parameters.
• Check the Deviation Abnormal Detection Value (OL
22).
• Check the motor capacity.
• Contact the maintenance department.
