(2) Remedies for alarms
CAUTION
When any alarm has occurred, eliminate its cause, ensure safety, then reset the
alarm, and restart operation. Otherwise, injury may occur.
POINT
When any of the following alarms has occurred, always remove its cause and
allow about 30 minutes for cooling before resuming operation. If operation is
resumed by switching control circuit power off, then on to reset the alarm, the
converter unit and regenerative option may become faulty.
Regenerative error (A.30)
Over load 1 (A.50)
Over load 2 (A.51)
Main circuit device overheat (A.45)
The alarm can be deactivated by switching the power off, then on or by the
error reset command from the host controller. Refer to (1) in this section for
details.
When an alarm occurs, the trouble (ALM) signal switches off and the display section shows the alarm number.
Remove the cause of the alarm in accordance with this section.
Display Name Definition Cause Action
A.10 Undervoltage Power supply voltage
dropped.
1. Instantaneous control power failure
occurred for more than 60ms.
Review the power supply.
2. Shortage of power supply capacity
caused the power supply voltage to
drop at start, etc.
3. Failure of the part in the converter
unit.
Checking method
Alarm (A.10) occurs if power is
switched on after connectors
disconnected.
Change the Converter unit.
A.12 Memory error 1
(RAM)

Checking method
Alarm (A.12) occurs if power is
switched on after connectors
disconnected.
Change the converter unit.
A.15 Memory error 2
(EEP-ROM)
EEP-ROM fault 1. Failure of the part in the converter
unit.
Checking method
Alarm (A.15) occurs if power is
switched on after connectors
disconnected.
Change the converter unit.
2. The number of write times to EEP-
ROM exceeded 100,000.
A.17 Board error CPU/parts fault Failure of the part in the converter unit. Change the converter unit.
A.19 Memory error 3
(Flash-ROM)
ROM memory fault
Checking method
Alarm (A.17/A.19) occurs if power is
switched on after connectors
disconnected.
