- 712 -
A.4 ERROR CODES (SERIAL SPINDLE)
NOTE
*1 Note that the meanings of the SPM indications
differ depending on which LED, the red or yellow
LED, is on. When the yellow LED is on, an error
code is indicated with a 2-digit number. An error
code is indicated in the CNC diagnosis, No.712.
When the red LED is on, the SPM indicates the
number of an alarm generated in the serial spindle.
→ See “(10) Serial spindle alarms (SP alarm).”

Faulty location and remedy Description
01 Although neither *ESP (emergency stop signal; there
are two types of signals including the input signal and
PSM contact signal) nor MRDY (machine ready
signal) is input, SFR (forward rotation signal)/SRF
(reverse rotation signal)/ORCM (orientation
command) is input.
Check the *ESP and MRDY sequence. For MRDY,
pay attention to the parameter setting regarding the
use of the MRDY signal (parameter No. 4001#0).
03 The parameter settings are such that a position
sensor is not used (position control not performed)
(bits 3, 2, 1, 0 of parameter No. 4002 = 0, 0, 0, 0), but
a Cs contour control command is input.
In this case, the motor is not excited.
Check the parameter settings.
04 The parameter settings are such that a position
sensor is not used (position control not performed)
(bits 3, 2, 1, 0 of parameter No.4002 = 0, 0, 0, ), but
a servo mode (rigid tapping, spindle positioning, etc.)
or spindle synchronization command is input.
In this case, the motor is not excited.
Check the parameter settings.
05
The orientation function option parameter is not
specified, but ORCM (orientation command) is
input.
Check the orientation function parameter settings.
06
The output switching control function option
parameter is not specified, but low-speed
characteristic winding is selected (RCH = 1).
Check the output switching control function
parameter settings and the power line state check
signal (RCH).
07
A Cs contour control command is input, but SFR
(clockwise rotation command)/SRV
(counterclockwise rotation command) is not input.
Check the sequence.
08
A servo mode (rigid tapping, spindle positioning,
etc.) control command is input, but SFR (clockwise
rotation command)/SRV (counterclockwise rotation
command) is not input.
Check the sequence.
09
A spindle synchronization command is input, but
SFR (clockwise rotation command)/SRV
(counterclockwise rotation command) is not input.
Check the sequence.
