ERR1
***
Temporary power loss
protection
When an instantaneous power failure occurs for
more than 15ms, the inverter output is switched off.
Once the instantaneous power failure wait time has
elapsed and the power has not been restored it is
regarded as a normal power failure.
However, when the operation command is still ON
with restart selection the inverter will restart. So
please be careful of this.
Inst. P-F
Abnormal temperature
When main circuit temperature raises by stopping of
cooling fan, the inverter output is switched off.
OH. FIN
Gate Allay error
Communication error between CPU and gate allay
indicate
GA
Open-phase protection
When an open-phase on the input supply occurs the
inverter output is switched off.
PH. Fail
IGBT error
When an instantaneous over-current is detected on
the output the inverter output is switched off to
protect the main devices.
IGBT
Thermistor error
When the Inverter detects a high resistance on the
thermistor input from the motor the inverter output is
switched off.
TH
Abnormal brake
When inverter cannot detect switching of the
brake(ON/FF) after releasing the brake ,and for
waiting for signal condition(b124) (When the braking
control selection(b120) is enable.)
BRAKE
Option 1 error 0-9
These indicate the error of option 1. You can realize
the details each instruction manual.
Option 2 error 0-9
These indicate the error of option 2. You can realize
the details by each instruction manual.
During under-voltage
waiting
When the incoming voltage of the inverter has
dropped, the inverter output is switched off and the
inverter waits.
