8.2.7 Troubleshooting Motion Errors
8-36
[ f ] Bit 6: Positioning Time Over
The above check is not performed if the Positioning Completion Cheek Time (OW 26) is set to 0.
[ g ] Bit 7: Excessive Positioning Moving Amount
[ h ] Bit 8: Excessive Speed
[ i ] Bit 9: Excessive Deviation
The above check is not performed if the Error Count Alarm Detection (OL 22) is set to 0.
Detection Timing
• Positioning was not completed within Positioning Completion Cheek Time (OW 26) after completing
pulse distribution.
Processing when
Alarm Occurs • The current command was ended forcibly.
• The Command Error Completed Status in the Motion Command Status (IW
0,9 bit 3) will turn ON.
Error and Cause
One of the following is possible.
• The position loop gain and speed loop gain are not set correctly, creating poor response. Or, there is oscil-
lation.
• The Positioning Completion Cheek Time (OW 26) is too short.
• The capacity of the motor is insufficient for the machine load.
• Connections are not correct between the SERVOPACK and the motor.
Correction
Check the following.
• Check the SERVOPACK gain parameters.
• Check connections between the SERVOPACK and the motor.
• Check the motor capacity.
• Check the Positioning Completion Cheek Time (OW
26).
Detection Timing
• Positioning command is executed.
Processing when
Alarm Occurs
• The move command is not executed.
• The Command Error Completed Status in the Motion Command Status (IW
09, bit 3) will turn ON.
Error and Cause
• A move command (commands for positioning, external positioning, or STEP operation) was executed that
exceeded the limit of the positioning moving amount.
Correction
• Check the moving amount for the axis being positioned.
Detection Timing
• A move command is executed.
Processing when
Alarm Occurs • The move command is not executed.
• The Command Error Completed Status in the Motion Command Status (IW
09, bit 3) will turn ON.
Error and Cause
• The speed (moving amount output for one scan in case of interpolation) commanded to MECHA-
TROLINK servo exceeds the upper limit.
Correction
• Check the settings for speed reference, interpolation command moving amount per scan, and speed com-
pensation.
Detection Timing
• Always except during speed control and torque control
Processing when
Alarm Occurs • The move command is not executed.
• The Command Error Completed Status in the Motion Command Status (IW
09, bit 3) will turn ON.
Error and Cause
One of the following is possible.
• The position loop gain and speed loop gain are not set correctly, creating poor response.
• The Error Count Alarm Detection (OL
22) is too small.
• The capacity of the motor is insufficient for the machine load.
• SERVOPACK failure
Correction
Check the following and correct the problem. If the problem persists, contact the maintenance department.
• Check the position loop gain and speed loop gain.
• Check the Error Count Alarm Detection (OL
22).
• Check the motor capacity.
