Description
Corrective Action
01
DC voltage alarm
Over voltage (OV)
DC bus voltage of the unit raised exces-
sively.
Change the MPS/MPR unit.
Change the MIV unit.
02
DC voltage alarm
Under voltage (UV)
DC bus voltage of the unit lowered exces-
sively.
Change the MPS/MPR unit.

excessively.
Change the MPS/MPR unit.
08
Over current in power
cable
Abnormal current flow in the power cable.
Check the power cable.
Change the MPS unit.
09
Power device error
(IPMF)
An error occurred with the power device.
Check the power cable.
Change the MPS unit.
10
Converter bridge short-
circuit (IOCR)
Abnormal current flow through the power
device.

11
Regeneration error
An error occurred with regeneration control. Check the power cable.
Change the MPS/MPR unit.
12
Overload in regenera-
tion (ROH)
Temperature of regeneration resistor raised
excessively. (MPR unit only)
Check the operation condi-
tions.
Change the MPR unit.
13
Heat sink overheat
(FOH)
Temperature of heat sink raised exces-
sively.
Check the operation condi-
tions.
Change the MPS/MPR unit.
14
Converter link error
An error occurred with data sending pro-
cessing in the converter link.
Check the communication
cables.
Change the MPS/MPR unit.
15
A/D error
An error occurred in A/D conversion.
Change the MPS/MPR unit.
16
Undefined alarm
An alarm not defined occurred.
Change the MPS/MPR unit.
17
Control power supply
error (+24 V voltage
error)
In the control circuit, +24 V raised or low-
ered excessively.
Check the control power
source voltage .
Change the MPS/MPR unit.
