This alarm will not occur once the system (including the spindle control unit) has started. It can occur before the system starts during power turn–on processing. Once the system has started, an error is indicated as system alarm 945.
(1) The fiber optics cable is poorly connected, or the power to the spindle amplifier is turned off.
(2) An attempt was made to switch the NC power on when the spindle amplifier display was SU–01 or any alarm condition other than AL–24. This condition occurs mainly if the NC power is switched off when the serial spindles are running. In this case, switch the power to the spindle amplifier off then back on.

These alarms indicate RAM parity errors.
RAM is provided with a check bit (parity bit). When data is written to RAM, the check bit is also written to the RAM by either setting it to 1 or resetting it to 0 so that the total number of 1 bits in the data, including the check bit, is even or odd. When the data is read from RAM, the check bit is used to ensure that the read data is correct.

(1) If any of these alarms occurs immediately after the power is switched
on, switch the power off then back on while holding down the RESET
and DELET keys so that the RAM is cleared to all 0s.
If a parity alarm still occurs after the RAM has been cleared to all 0s, it is likely that the printed–circuit board on which the RAM in which the alarm has occurred is defective. So, replace the printed–circuit board. * Re–set all data according to Chapter 3 ”Data input/output.”

4n7 SERVO ALARM: n–TH AXIS – PA- RAMETER INCORRECT
This alarm occurs when the n–th axis is in one of the conditions listed below. (Digital servo system alarm) 1) The value set in Parameter No. 8n20 (motor form) is out of the
specified limit. 2) A proper value (111 or –111) is not set in parameter No. 8n22

408 SPINDLE SERIAL LINK START FAULT
This alarm is generated when the spindle control unit is not ready for starting correctly when the power is turned on in the system with the serial spindle. The four reasons can be considered as follows: 1) An improperly connected optic cable, or the spindle control unit’s
power is OFF. 2) When the NC power was turned on under alarm conditions other
than SU–01 or AL–24 which are shown on the LED display of the spindle control unit. In this case, turn the spindle amplifier power off once and perform startup again.

The installation conditions and method for the CRT/MDI for the Series 00 are basically the same as in 9″ CRT/MDI unis. Therefore, refer to item 3 in the text. Follow this reference material, however, for the following items.
This unit’s heating value is about 170 W. The pendant, etc. on which to mount this unit should be designed as follows so that the inside temperature does not rise more than 15�C above the outside temperature.
1) Heat absorber
The conventional 14″ CRT/MDI unit heat absorber has insufficient radiation. A special heat absorber is available for this unit. (It is a little different from the conventional 14″ CRT/MDI unit heat absorber in size.)
2) Air agitation fan in cabinet
An air agitation fan (1) should be installed at the position shown in the figure below so that air flows between the printed circuit boards at 0.5m/sec. (A special fan unit is available.)

NOTE 1 Connection with the battery unit is necessary only when using RAM file. 2 A cable (3.4m) is attached to the battery unit for CRT/MDI. 3 Connection with the battery unit on the CNC side is also possible. In this case, the cable should
be manufactured by the machine tool builder. Wire gauge : 30/0.18 (0.75mm2) and over twist pair, shielding Connector contact : Gold–plated

In a system with a printed–circuit board incorporating a high–speed CPU and a software version modified for the high–speed CPU, it is possible to forcibly reduce the throughput to the conventional level (usually set to 0). If the A20B–2002–0650 is being used as the master printed circuit board, this parameter must be set to 0.
