(4) Absolute pulse coder (APC) alarm
Number Message Contents
300 nth--axis origin return Manual reference position return is required for the nth--axis (n=1 -- 8).
301 APC alarm: nth--axis communication nth--axis (n=1 -- 8) APC communication error. Failure in data transmis-
sion
Possible causes include a faulty APC, cable, or servo interface module.
302 APC alarm: nth--axis over time nth--axis (n=1 -- 8) APC overtime error.
Failure in data transmission.
Possible causes include a faulty APC, cable, or servo interface module.
303 APC alarm: nth--axis fra ming nth --axis (n=1 -- 8) APC framing error. Failure in data transmission.
Possible causes include a faulty APC, cable, or servo interface module.
304 APC alarm: nth--axis parity nth--axis (n=1 -- 8) APC parity error.
Failure in data transmission.
Possible causes include a faulty APC, cable, or servo interface module.
305 APC alarm: nth--axis pulse error nth --axis (n=1 -- 8) APC pulse error alarm.
APC alarm.APC or cable may be faulty.
306 APC alarm: nth--axis battery
voltage 0
nth--axis (n=1 -- 8) APC battery voltage has decreased to a low level so
that the data cannot be held.
APC alarm. Battery or cable may be faulty.
307 APC alarm: nth--axis battery low 1 nth --axis (n=1 -- 8) axis APC battery voltage reaches a level where the
battery must be renewed.
APC alarm. Replace the batte ry.
308 APC alarm: nth--axis battery low 2 nth --axis (n=1 -- 8) APC battery voltage has reached a level where the
battery must be renewed (including when power is OFF).
APC alarm .Replace battery.
309 APC ALARM:
n AXIS ZRN IMPOSSIBL
Return to the origin has been attempted without first rotating the motor
one or more times. Before returning to the origin, rotate the motor one
or more times then turn off the power.
No. Message Description
