Description

During con-

stant speed

OC.  Drive

Deceleration

OC.  Decel

Acceleration

OC.  Accel

Overcurrent

protection

When the output of the inverter is

short circuited, the motor is

locked, or a heavy load is

suddenly applied, and the inverter

output current exceeds a

predetermined level, the inverter

is shut off.

At the others

Over.  C

Overload

protection

When a motor overload is detected by the electronic

thermal function, the inverter is shut off

Over.  L

Breaking resistor

overload

When the allowable relative duration for the V2000

built-in breaking unit entered under 

b 90 

is

exceeded, the inverter will be shut off

OL. BRD

When the inverter DC bus voltage exceeds a

predetermined level due to regenerative energy from

the motor, this trip occures and the inverter is shut

off.

Over.  V

Overvoltage

protection

100s after the input power supply voltage has

exceeded the allowable voltage limit, the output

voltage will be switched off.

OV.  SRC

EEPROM error

When the inverter memory has a problem due to

noise

or excessive temperature rise, this trip occurs and

the inverter is shut off.

EEPROM

Undervoltage

protection

A decrease of DC bus voltage may result in

improper function of the control unit. It may also

cause motor heating and low torque. The inverter is

shut off when the DC bus voltage goes below a

certain level.

Under.  V

CT error

If the V2000 built-in current transformer is not

functioning properly, the inverter will be shut off.

CT

CPU1

CPU error

Malfunction or abnormality of the CPU.

The inverter is shut off.

CPU2

External trip

A trip signal from external equipment shuts off the

inverter. It is necessary to assign the external trip to

an intelligent input terminal.

EXTERNAL

USP error

Indicates an error when power is turned on while the

inverter run is enabled (when USP function is

selected).

USP

Ground fault

protection

The inverter is protected by detection of ground

faults between the drive output and the motor at

power on. Protection is for the inverter only and not

for humans.

GND.  Flt

Thermal

protection

When the temperature of the inverter module is

beyond specification, the thermal sensor in the

inverter module detects the temperature and the

inverter is shut off.

OH  FIN

PTC error

When the resistance value of the external

thermistor is too large, the equipment detects the

abnormal condition of the thermistor and then

shuts off the inverter (when PTC function is

selected).
