Checking Parameters Using the Spindle Check Board
4.3.7.1 Overview
By using the check board, you can check parameter values transferred to the Spindle Amplifier. Specify
parameter numbers using the four setting switches on the check board, and check parameter values on the
five-digit indicator.
4.3.7.2 Checking parameters
<1> Press the four setting switches at the same time for at least one second. "FFFFF" will be displayed on
the indicator.
<2> Turn off the switches and press the "MODE" switch. "d-00" will be displayed on the indicator and the
system will enter the mode for measuring internal data.
<3> With "0" set for "d-00", press the "MODE" and "DATA SET" switches at the same time for at least one
second. "CCCCC" will be displayed on the indicator.
<4> Turn off the switches and press the "MODE" switch. "F-xxx" will be displayed on the indicator and the
system will enter the mode for checking spindle parameters (F-mode). (Even in this mode, the motor
can be operated normally.)
<5> Press the "UP" or "DOWN" switch while holding down the "MODE" switch (with "F-xxx" displayed).
The number of "F-xxx" increases or decreases. Set the internal number of a parameter you want to
check. For correspondences between the parameter internal numbers and NC parameter numbers, see
the parameter list in the appendix to the parameter manual.
<6> Turn off the switches. The parameter value corresponding to the set internal number is displayed for
about one second. (Bit parameter values are displayed in hexadecimal.)

3 TROUBLESHOOTING AND ACTION
3.1
POWER SUPPLY (αiPS, αiPSR)
If an alarm occurs, in the STATUS display, the ALM LED lights red, and the one-digit 7-segment display
indicates an alarm code or warning code.
The meaning of each warning code is the same as that of the corresponding alarm code. If a warning
code is displayed, an alarm condition will occur in a certain period of time. The Power Supply remains
operable while the warning code stays displayed.
Example of an alarm
Example of a warning
code display

When a lightning surge absorber is connected immediately following the circuit breaker, check
whether the lightning surge absorber is short-circuited by lightning. If the lightning surge
absorber is short-circuited, replace it.
(b) Disconnect the cable from the connector CX1A and turn the control power on. If "-" is displayed,
the 24-V power to a Servo Amplifier or Spindle Amplifier may be short-circuited.
→ Detect the amplifier which causes the power to be short-circuited by sequentially
connecting the cable from the Power Supply and replace it.
(c) Disconnect the cable from the connector CX4 and turn the control power on. If "-" is displayed,
the external 24-V power may be connected to pin 3 of CX4 incorrectly.
→ Correct the connection.
