POWER Green Indicates that power supply for control circuit of the VAC drive unit is being supplied.
If this LED is OFF while' power supply to the VAC drive unit is O N , it indi-cates failure of the unit.
LOSS Red Indicates chat voltage being
applied to the operation
circuit in the VAC drive
unit is outside the speci-
fication.
If this LED lights up, it
indicates that the operation
circuit is not functioning

Faulty Operation Status Indication
A faulty operation status is indicated by the LED 1s Ml and M2 in the following conditions.
a) Ml and M2 flicker simultaneously. b) Ml lights up. c) M2 lights up.
LED's other than Ml and M2 light up corresponding to the failure conditions occurred to indicate them.
In any case, operations of the VAC drive unit become impossible.
Indication method of the failure contents differs depending on the ROM version. For ROM version, refer to Appendix 2.
