SPINDLE SERIAL LINK ERROR

This alarm is generated when the spindle control unit is

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 startups again.

3. Other reasons (improper combination of hardware)

This alarm does not occur after the system including

the spindle control unit is activated.

Spindle Amplifier Module

If an alarm occurs in the spindle amplifier module, the ALM LED lights red in the STATUS display,

and the two-digit 7-segment LEDs indicate the alarm code.

<Error No. 01>

<Alarm No. 01>.

1-1. Alarm A0. A1

(1) Meaning

The control program is not running.

(2) Cause and corrective action

a) ROM installed improperly or yet to be installed.

Make sure that the ROM is attached properly to the socket and there is no imperfect

contact due to a broken or bent pin.

⇒ Install the ROM properly.

b) Incorrect ROM installed

The series number of the software is printed on the ROM package and is displayed at

power-on.

⇒ Replace it with the correct ROM.

c) Printed-circuit board defective

⇒ Replace it with a normal printed circuit board.

1-2. Alarm AL-01

(1) Meaning

The temperature inside the motor is higher than the rating.

(2) Cause and corrective action

a) Over loaded operation

Check the cutting conditions, the state of the cutting tool, and the load meter reading

A-1

APPENDIX

⇒ Set the parameter with a value somewhat greater (margin) than the required

acceleration/deceleration duration.

d) Incorrect speed detector parameter setting

Check the parameter setting and the speed detector.

f)

Speed feedback signal faulty

Check the speed feedback signal level.

⇒ Check the speed detector. Also check the signal cable for continuity.

1-4. Alarm AL-03

(1) Meaning

The fuse at the DC link has blown.

(2) Cause and corrective action

a) Overcurrent flowed in the main circuit.

A-3

abnormal.

(2)

Cause and corrective action

a)

Feedback signal level insufficient

Check the connection of the cable. Also check for a broken wire.

⇒ Connect the cable correctly. If any wire in the cable is broken, replace it

b)

Feedback signal level insufficient

Check the feedback signal level with an oscilloscope.

⇒ Adjust so that the feedback signal level becomes the rated value.

c)

Feedback signal cable not shielded properly (circuit malfunction due to nois(e).

Check whether the cable is shielded properly.

⇒ Shield it correctly.

d)

Detection circuit defective

⇒ Replace the printed-circuit board.

e)

Incorrect parameter setting

Check the parameter set to specify use of the Cs contouring control detector.

4011 #2

Parameter set to specify use of the Cs contouring control

detector.

⇒ Set the parameter correctly according to the detector used.

1-18.

Alarm AL-29

(1)

Meaning

Excessive load (at least 90% of the maximum output as set initially by a parameter)

was applied continuously for a certain

(2)

Cause and corrective action

a)

Overloaded operation, or too heavy load

Check the load meter to see if the load is too heavy.

⇒ Examine the cutting conditions and the tool again.

Alarm AL-37

(1)

Meaning

When an emergency stop signal was entered, the motor did not decelerate, rather

accelerate, or the motor was kept excited even after acceleration/deceleration duration

(10 seconds as set initially by a parameter).

(2)

Cause and corrective action

a)

Incorrect speed detector parameter setting

Check the parameter setting and the speed detector.
