Sinusoidal PWM control
Adjustable within the range of 50 to 330V (240V class) and 50 to 660V (500V class) by correcting the supply
voltage
0.1 to 500.0Hz, default setting: 0.5 to 80Hz, maximum frequency: 30 to 500Hz
0.1Hz: analog input (when the max. frequency is 100Hz), 0.01Hz: Operation panel setting and communication
setting.
Digital setting: within ±0.01% of the max. frequency (-10 to +60°C)
Analog setting: within ±0.5% of the max. frequency (25°C ±10°C)
V/f constant, variable torque, automatic torque boost, vector control, automatic energy-saving, dynamic automatic
energy-saving control (for fan and pump), PM motor control, V/F 5-point setting, Auto-tuning. Base frequency (20-
500Hz) adjusting to 1 & 2, torque boost (0-30%) adjusting to 1 & 2, adjusting frequency at start (0.1-10Hz)
Setting dial on the front panel, external frequency potentiometer (connectable to a potentiometer with a rated
impedance of 1k-10kΩ), 0-10Vdc / -10-+10Vdc (input impedance: 30kΩ), 4-20mAdc (Input impedance: 250Ω).
The characteristic can be set arbitrarily by two-point setting. Possible to set: analog input (VIA, VIB, VIC).
Three frequencies can be set. Setting of the jump frequency and the range.
Upper-limit frequency: 0.5 to max. frequency, lower-limit frequency: 0 to upper-limit frequency
Adjustable range of 2.0k to 16.0kHz (default: 12.0kHz).
Setting of proportional gain, integral gain, differential gain and control waiting time. Checking whether the amount of
processing amount and the amount of feedback agree.
Selectable from among acceleration/deceleration times 1 & 2 & 3 (0.0 to 3600 sec.). Automatic
acceleration/deceleration function. S-pattern acceleration/deceleration 1 & 2 and S-pattern adjustable. Control of
forced rapid deceleration and dynamic rapid deceleration.
Braking start-up frequency: 0 to maximum frequency, braking rate: 0 to 100%, braking time: 0 to 25.5 seconds,
emergency DC braking, motor shaft fixing control.
Control and drive circuit is built in the inverter with the braking resistor outside (optional).
Possible to select from among about 110 functions, such as forward/reverse run signal input, jog run signal input,
operation base signal input and reset signal input, to assign to 8 input terminals. Logic selectable between sink and
source.
Possible to select from among about 150 functions, such as upper/lower limit frequency signal output, low speed
detection signal output, specified speed reach signal output and failure signal output, to assign to FL relay output,
open collector output terminal, and RY output terminals.
The RUN and STOP keys on the operation panel are used to start and stop operation, respectively.
Forward/reverse run possible through communication and logic inputs from the terminal block.
Jog mode, if selected, allows jog operation from the terminal block and also from remote keypad.
Frequency references + 15-speed operation possible by changing the combination of 4 contacts on the terminal
block.
Capable of restarting automatically after a check of the main circuit elements in case the protective function is
activated. 10 times (Max.) (selectable with a parameter)
Possible to write-protect parameters and to prohibit the change of panel frequency settings and the use of operation
panel for operation, emergency stop or resetting. Possible to write-protect parameters by setting 4 digits password
and terminal input.
Possible to keep the motor running using its regenerative energy in case of a momentary power failure (default:
OFF).
In the event of a momentary power failure, the inverter reads the rotational speed of the coasting motor and outputs
a frequency appropriate to the rotational speed in order to restart the motor smoothly. This function can also be
used when switching to commercial power.
Increases the operating efficiency of the machine by increasing the rotational speed of the motor when it is operated
under light load.
When two or more inverters are used to operate a single load, this function prevents load from concentrating on one
inverter due to unbalance.
External input signal adjustment is possible to the operation frequency command value.
