(14) Bit 11: Servo Driver Communication Error
• Detected by the communication control section when communication is not synchronized between
Detection Timing
the MP2100/MP2100M and SERVOPACK.
Processing when • The current command will be aborted.
Alarm Occurs
• The SERVOPACK will be Servo OFF status.
• MECHATROLINK communication stopped because the cable was disconnected, there is noise
Error and Cause
interference to the communication line or the power supply to the SERVOPACK was turned OFF.
• Check the MECHATROLINK cable and reset the alarm.
Correction
• If this error occurs frequently, refer to the MECHATROLINK-II Installation Manual (Manual No.:
SIEP S800000 30) to correct the wiring and eliminate noise interference.
(15) Bit 12: Servo Driver Command Timeout Error
• Detected during execution of each motion commands.
Detection Timing
• Detected by the MECHATROLINK communication control section when the Servo command
responses are checked for each process.
Processing when
• The current command will be aborted.
Alarm Occurs
Error and Cause • The MECHATROLINK Servo command did not complete within the specified time (5 s).
Correction • Check for alarms in the SERVOPACK for MECHATROLINK communication.
Note: The above error occurs when Module allocations of SERVOPACK for MECHATROLINK communication
have been completed and the power is not being supplied to the SERVOPACK.
(16) Bit 13: Excessive ABS Encoder Rotations
• Enabled only when an absolute encoder is used for a finite length axis, and the electronic gear used.
Detection Timing
Detected by the position management section when power is turned ON.
Processing when • The absolute position information read from the absolute encoder when the SEN signal turned ON
Alarm Occurs is ignored.
• An operation error occurred when the absolute position information read from the absolute encoder
Error and Cause
is converted from pulses to reference units at power ON.
Correction
• Check the gear ratio, number of encoder pulses for other motion fixed parameters.
(17) Bit 1E: Motor Type Set Error
Detection Timing • Detected when communications with the SERVOPACK are established.
Processing when
• None
Alarm Occurs
• The motor type setting (rotary/linear) of the fixed parameters does not agree with the SERVOPACK
Error and Cause
setting (for SGDH: startup selection setting Pn000.3, for SGDS: for rotary/for linear).
Correction • Check the setting and model of the SERVOPACK.
(18) Bit 1F: Connected Encoder Type Error
Detection Timing • Detected when communications with the SERVOPACK are established.
Processing when
• None
Alarm Occurs
• The motor type setting (rotary/linear) of the fixed parameter does not agree with the actual motor
Error and Cause
connected to the SERVOPACK.
Correction • Check the motor.
