Detail specifications
Overload
Inverter protection electronic thermal overload relay
protection
Overvoltage
An excess in the DC link circuit voltage (approx. 400 Vdc for 200V class, approx.
protection
800Vdc for 400V class) is detected for inverter protection.
Overcurrent
The inverter is protected against an overcurrent caused by an overload on the
protection
output side.
Surge
The inverter is protected against a surge voltage penetrating between the power
protection
supply cable of the main circuit and the ground.
Undervoltage
Voltage drop (approx. 200 Vdc for 200V class, approx. 400Vdc for 400V class)
protection
in the DC link circuit voltage is detected to stop the inverter.
Overheat
The inverter is protected against failure of the cooling fan.
protection
Short-circuit
The inverter is protected against an overcurrent caused by a short-circuit on the
protection
output side.
Ground fault
The inverter is protected against an overcurrent caused by ground fault in the
protection
output wiring.
* Detection when starting
Motor protection
Electronic thermal overload relays protect general purpose motors.
The thermal time constant can be adjusted to 0.5 to 10.0 min.
Second electronic thermal overload relay can be provided. (Switching with
external signal)
Braking resistor
Upon an overheat of the damping resistor (external unit), discharging operation

and inverter operation stop
Stall prevention
• When the output current exceeds the limit during acceleration, the frequency
(simple torque limit) ramp is suspended to avoid overcurrent stop.
• When the output current exceeds the setting during constant speed operation,
the frequency is decreased to maintain an almost constant torque.
• When the DC voltage exceeds the limit during deceleration, the frequency
ramp is suspended to avoid overvoltage trip.
Input phase loss
The inverter is protected against phase loss of the input voltage.
protection
Output phase loss
An unbalance in the impedance of the output circuit is detected to output an
protection
alarm. (Error during tuning only)
Auto reset
The number of retries and wait time can be set for a fault trip.
