SJ100 Inverter
Troubleshooting
and Maintenance
6–7
NOTE: If an EEPROM error (E08) occurs, be sure to confirm the parameter data values
are still correct. If the power is turned off while the [RS] (Reset) intelligent input
terminal is On, an EEPROM error will occur when power is restored.
E14
Ground fault The inverter is protected by the detection of ground
faults between the inverter output and the motor upon
during powerup tests. This feature protects the
inverter, and does not protect humans.
E15
Input over-voltage When the input voltage is higher than the specified
value, it is detected 100 seconds after powerup and
the inverter trips and turns off its output.
E21
Inverter thermal trip When the inverter internal temperature is higher than
the specified value, the thermal sensor in the inverter
module detects the higher temperature of the power
devices and trips, turning the inverter output off.
E35
PTC error When intelligent terminal 5 is configured for PTC
(protective thermistor) function and the inverter has
sensed the resistance is too high (wire is broken or
temperature is too high), the inverter trips and turns
off the output.
