Causes and countermeasures

IO-1

I/O error
(gate turn-off
circuit error)

1. The VAT2000 may be malfunctioning due to external noise,

etc. Look for the noise source and remove the cause.
The control circuit may be faulty.

IO-2

I/O error
(A/D converter
error)

IO-3

I/O error
(current detection
error)

1. The current detector connectors may be connected

improperly. Properly connect these.

2. The current detection may be faulty.

IO-4

I/O error
(retry time-out)

1. Retry has failed. There are no countermeasures for this code,

so reset the VAT2000.

IO-E

I/O error
(thermistor error)

1. Securely connect the thermistor connector.

IO-F

I/O error
(speed detection
error)

1. This indicates that there is an error in the speed detection

operation results.
Check the speed detection signal wiring, connection and the
speed detector.

CPU-1~CPU-8

CPU error

1. The unit may be malfunctioning due to external noise, etc.

Look for the noise source and remove the cause.

2. The control circuit may be faulty.
3. For all sub-codes other than 8, turn the power off and on once.

EEPROM
data error

The parameter setting value is incorrect. Correct the parameter
setting value with the following procedure.

(1)

Select D20-2 with the monitor mode, and press the set
key. The parameter for which an error occurred will
display.

(2)

Set the correct parameter in this state.

(3)

Display the parameters in order with the

knob.
