Input data 2 is invalid. Operation can not be activated because an invalid mode is specified or because block execution is in progress. The interface switch signal (DRC) was switched during block execution.

Check input data 2, specified with afunction code.

Pulse coder alarms No. LED display Description Countermeasure Check the continuity of the signal cable. If the cable is normal, the pulse coder may be defective. Turn the power off. If the alarmrecurs, replace the serial pulse coder and motor.

300

A communication error (DTER) for the serial pulse coder was detected.

301

A communication error(CRCER) for serial pulse coder was detected.

Check the continuity of the signal cable. If the pulse coder is normal, the pulse coder or servo unit may be defective. This error can also be caused by external noise.

302

Acommunication error (STBER) for serial pulse coder was detected.

Check the continuity of the signal cable. If the cable is normal, the pulse coder or servo unit may be defective. This error can also be caused by external noise.
