Auto search The motor speed is estimated before startup, and the motor is started without ever stopping the motor while it is idling. (Motor constant tuning required : offline tuning)
Anti-regenerative control
  • If the DC link bus voltage/torque calculation value reach or exceed the anti-regenerative control level when the motor is decelerating, the deceleration time is automatically extended to avoid an overvoltage trip. (Forced deceleration can be set at three or more times the deceleration time.)
  • If the torque calculation value reaches or exceeds the anti-regenerative control level during constant speed operation, overvoltage tripping is avoided by performing control to raise the frequency.
Deceleration characteristic (improved braking ability)
  • During deceleration, this function increases the motor energy loss and decreases the regenerative energy returned to avoid an overvoltage trip.
  • Setting is also possible when using in combination with AVR cancel.)
Auto energy saving operation Controls the output voltage in order to minimize the total motor and inverter power loss at constant speed.
Overload prevention control If the surrounding temperature or IGBT junction temperature increases due to an overload, the inverter lowers the output frequency to avoid an overload.
Battery operation Cancels the undervoltage protection so that the inverter under an undervoltage condition runs the motor with battery power.

  • The number of attempts can be set up to 20 times (can be set with function code)
Auto search The motor speed is estimated before startup, and the motor is started without ever stopping the motor while it is idling. (Motor constant tuning required : offline tuning)
Anti-regenerative control
  • If the DC link bus voltage/torque calculation value reach or exceed the anti-regenerative control level when the motor is decelerating, the deceleration time is automatically extended to avoid an overvoltage trip. (Forced deceleration can be set at three or more times the deceleration time.)
  • If the torque calculation value reaches or exceeds the anti-regenerative control level during constant speed operation, overvoltage tripping is avoided by performing control to raise the frequency.
Deceleration characteristic (improved braking ability)
  • During deceleration, this function increases the motor energy loss and decreases the regenerative energy returned to avoid an overvoltage trip.
  • Setting is also possible when using in combination with AVR cancel.)
Auto energy saving operation Controls the output voltage in order to minimize the total motor and inverter power loss at constant speed.
Overload prevention control If the surrounding temperature or IGBT junction temperature increases due to an overload, the inverter lowers the output frequency to avoid an overload.
Battery operation Cancels the undervoltage protection so that the inverter under an undervoltage condition runs the motor with battery power.

Excessive positioning deviation Stops the inverter and displays an error if the position deviation is found to be excessive while performing position control. d0
Overspeed protection Stops the inverter and displays an error if the following conditions are met.
  • If d35 = 999, the speed detection value is the maximum output frequency x (d32 or d33) x 120% or higher
  • If d35 ≠ 999, the speed detection value is the maximum output frequency x (d35) or higher
  • The detected speed exceeds 599 Hz

Magnetic pole position detection error Stops the inverter and displays an error if the signal from the magnetic pole position sensor mounted on the PM motor is abnormal. ErC
Step-out detection／ detection failure of magnetic pole position at start This occurs when a PM motor step-out is detected, or if magnetic pole position at start failed to be detected. Erd
Speed mismatch or excessive speed deviation Stops the inverter and displays an error if an excessive deviation appears between the reference speed and detected/estimated speed. ErE
Password protection Stops the inverter and displays an error if a malicious person tries to unlock the password set by the customer. LoK
Customizable logic error Stops the inverter and displays an alarm when the alarm condition defined by the customer in the customizable logic is met. (It is not an alarm related to the inverter faults) ECL
Simulation fault A simulation fault can be produced if the keypad STOP key and FUNC/DATA key are held down for 5 seconds or longer.
A simulation fault can be produced even if function code H45 is set to “1”.		 Err
Current input terminal signal wire break detection Stops the inverter and displays an alarm if a current input wire break is detected when current is less than 2 mA when using the current input terminal (terminal [C1] or [C2]) as current input 4 to 20 mA. CoF
Customizable logic alarm An error is displayed if the alarm conditions defined by the user with customizable logic are met. (This is not an error at the inverter itself.) CA1

Integrated alarm Relay signals are output while the inverter is stopped due to an alarm.
The alarm is cleared with digital input signal “RST”.
(Reset the alarm using the [PRG/RESET] key on the optional multi-function keypad.)
Retry The inverter can be automatically reset allowing it to be restarted when it stops due to a trip. (The number of retries and the latency between stop and reset can be specified.)
Surge protection This function protects the inverter from a surge voltage between main circuit power lines and the ground.

Item Detailed Specifications Remarks
Main circuit power cutoff detection Inverter operation is not possible when the inverter AC input power supply (main power supply) is not ON.
In such cases as when supplying power via a PWM converter or when using a DC bus bar connection, set main circuit power cutoff detection to “None”.
Forced operation (Fire mode) Alarms other than critical alarms are ignored, and a retry is performed forcibly. Fod
