Item Explanation

Frequency limiter High and low limiters [Hz] can be set. (Setting range: 0 to 400 Hz)
Bias frequency Biases of set freq. and PID command can be set between 0 and ±100%.
Gain for frequency
setting
Analog input gain can be set within the range from 0 to 200%.
At voltage input, proportional frequency can be set to 10.5V and 21mA by adjusting gain.
Jump frequency
control
Three operation points and their jump hysteresis width (0 to 30Hz) can be set.
Jogging operation Operation by the RUN key or digital input signal (FWD¤REV)
(Frequency setting and ACC/DEC time common setting exclusive for jogging)
Auto-restart after
momentary power
failure
Restarts the drive without stopping the motor after instantaneous power failure.
Slip compensation Compensates for decrease in speed according to the load during constant speed operation.
Current limit
(By hardware)
(By software)
Limits the current to prevent overcurrent trip caused by rapid load change or instantaneous power failure
when current limitation by the software is impossible.
(This function can be canceled.)
Automatically reduces the frequency to make output current under the preset value.
(Current limit condition can be selected from between “constant speed operation only” and “acceleration
and constant speed operation”.)
PID control
Process PID control can be made.
Process command: Keypad, built-in potentiometer, analog input (12, C1), RS485 communication
Feedback signal: Analog input (12, C1)
Automatic
deceleration
Makes the deceleration time 3 times longer to avoid OV trip when dc link circuit voltage exceeds the
overvoltage limit.
Auto energy saving
operation
Controls output voltage to minimize motor loss during constant speed operation.
(Torque boost during acceleration can be selected from manual variable torque, manual constant torque, and
auto torque.)
Overload prevention
control
Decreases the output frequency automatically to prevent tripping before the inverter’s overload preventive
function is activated by ambient temperature rise, frequent use, or large motor load.
Cooling fan stop
operation
Detects drive inside temperature and stops cooling fan when the temperature is low.
