4) Serial pulse coder (SPC) alarms
If one of the following alarms is issued, replace the pulse coder, feedback
cable, and servo amplifier in this order:
Number Message Contents
360 n AXIS : ABNORMAL CHECKSUM (INT) A checksum error occurred in the builtin pulse coder.
361 n AXIS : ABNORMAL PHASE DATA
(INT)
A phase data error occurred in the builtin pulse coder.
362 n AXIS : ABNORMAL REV.DATA (INT) A rotation speed count error occurred in the builtin pulse coder.
363 n AXIS : ABNORMAL CLOCK (INT) A clock error occurred in the builtin pulse coder.
364 n AXIS : SOFT PHASE ALARM (INT) The digital servo software detected invalid data in the builtin pulse
coder.
365 n AXIS : BROKEN LED (INT) An LED error occurred in the builtin pulse coder.
366 n AXIS : PULSE MISS (INT) A pulse error occurred in the builtin pulse coder.
367 n AXIS : COUNT MISS (INT) A count error occurred in the builtin pulse coder.
368 n AXIS : SERIAL DATA ERROR (INT) Communication data from the builtin pulse coder cannot be received.
369 n AXIS : DATA TRANS. ERROR (INT) A CRC or stop bit error occurred in the communication data being
received from the builtin 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 detector.
385 n AXIS : SERIAL DATA ERROR (EXT) Communication data from the separate detector cannot be received.
386 n AXIS : DATA TRANS. ERROR (EXT) A CRC or stop bit error occurred in the communication data being
received from the separate detector.

SPH
SPH : The serial pulse coder or feedback cable is defective. Replace the serial
pulse coder or cable.
CKA : The serial pulse coder is defective. Replace it.
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).
PCA : The serial pulse coder is defective. Replace it.
PHA : The serial pulse coder or feedback cable is defective. replace the serial
pulse coder or cable.
BLA : The battery voltage is low. Replace the batteries. This alarm has nothing
to do with alarm No. 350 (serial pulse coder alarm).
CSA : The serial pulse coder is defective. Replace it.
D The details of serial
pulse coder alarm
No.350
