No. Message Description
360 n AXIS : ABNORMAL CHECKSUM
(INT)
A checksum error occurred in the built to in pulse coder.
361 n AXIS : ABNORMAL PHASE DATA
(INT)
A phase data error occurred in the built to in pulse coder.
362 n AXIS : ABNORMAL REV.DATA
(INT)
A rotation speed count error occurred in the built to in pulse coder.
363 n AXIS : ABNORMAL CLOCK (INT) A clock error occurred in the built to in pulse coder.
364 n AXIS : SOFT PHASE ALARM (INT) The digital servo software detected invalid data in the built to in pulse
coder.
365 n AXIS : BROKEN LED (INT) An LED error occurred in the built to in pulse coder.
366 n AXIS : PULSE MISS (INT) A pulse error occurred in the built to in pulse coder.
367 n AXIS : COUNT MISS (INT) A count error occurred in the built to in pulse coder.
368 n AXIS : SERIAL DATA ERROR
(INT)
Communication data from the built to in pulse coder cannot be re-
ceived.
369 n AXIS : DATA TRANS. ERROR
(INT)
A CRC or stop bit error occurred in the communication data being
received from the built to in pulse coder.
380 n AXIS : BROKEN LED (EXT) The separate detector is erroneous.
381 n AXIS : ABNORMAL PHASE
(EXT LIN)
A phase data error occurred in the separate linear scale.
382 n AXIS : COUNT MISS (EXT) A pulse error occurred in the separate detector.
383 n AXIS : PULSE MISS (EXT) A count error occurred in the separate detector.
384 n AXIS : SOFT PHASE ALARM
(EXT)
The digital servo software detected invalid data in the separate de-
tector.
385 n AXIS : SERIAL DATA ERROR
(EXT)

#0 (SPH) : The serial pulse coder or feedback cable is defective. Replace the serial
pulse coder or cable.
#1 (CKA) : The serial pulse coder is defective. Replace it.
#2 (BZA) : The pulse coder was supplied with power for the first time.
Make sure that the batteries are connected.
Turn the power off, then turn it on again and perform a reference position
return. This alarm has nothing to do with alarm No. 350 (serial pulse
coder alarm).
#3 (RCA) : The serial pulse coder is defective. Replace it.
#4 (PHA) : The serial pulse coder or feedback cable is defective. Replace the serial
pulse coder or cable.
#5 (BLA) : The battery voltage is low. Replace the batteries. This alarm has nothing
to do with alarm No.350 (serial pulse coder alarm).
#6 (CSA) : The serial pulse coder is defective. Replace it.
