11.2 Common Specifications

Explanation

Sinusoidal wave PWM control (with V/F control, torque vector control, PG feedback vector
control (option)

Maximum
frequency

50 to 400 Hz variable setting

Base
frequency

25 to 400 Hz variable setting

Starting
frequency

0.1 to 60 Hz variable setting Holding time: 0.0 to 10.0 s

Carrier
frequency

0.75 to 15k Hz (75 HP or less) 0.75 to 10k Hz (100 HP or more)

Accuracy
(stability)

Analog setting: +/- 0.2% or less of the max. frequency (at 25 +/- 10°C)
Digital Setting: +/- 0.01% or less of the max frequency (-10 to +50°C)

Setting
resolution

Analog setting: 1/3000 of max. frequency (e.g. 0.02 Hz / 60 Hz, 0.05 Hz / 150 Hz) Digital setting: 0.01
Hz (99.99 Hz or less), 0.1 Hz (100.0 Hz or more)

Output voltage at base frequency can be adjusted separately, such as 80 to 240V (200V series) or
320 to 480V (400V series)

Auto: Optimum control corresponding to the load torque.

Manual: 0.1 to 20.0 code setting (energy savings reduced torque, constant torque (strong) etc.)
0.01 to 3600s
Four accelerating and decelerating time settings are possible independent of each other by
selecting digital input signals.

In addition to linear acceleration and deceleration, either S-shaped acceleration/deceleration
(weal/strong) or curvilinear acceleration/deceleration can be selected.

Starting frequency: 0.0 to 60 Hz, braking time: 0.0 to 30.0s
Braking levels: 0 to 100%

Frequency upper and lower limiter, bias frequency, frequency gain, jump frequency, pick-up
operation, restart after momentary power failure, switching operation from line to drive, slip
compensation control, automatic energy saving operation, regeneration avoiding control, droop
control, torque limiting (2-strp), torque control, PID control, second motor switching, cooling fan
ON/OFF control.

Keypad panel: Run by FWD REV keys, stop by STOP key.
Terminal input: Forward/Stop command, Reverse/Stop command, Coast-to-Stop command,
Alarm reset, acceleration/deceleration selection, multistep frequency selection, etc.

Keypad panel: setting by UP and DOWN keys
External potentiometer: External freq. Setting POT (VR) (1 to 5k ohm)
Analog input: 0 to +10V (0 to 5V), 4 to 20 mA, o to ± 10V (FWD/REV operation)
+10 to 0 (reverse operation), 20 to 4 mA (reverse operation)
UP/DOWN control: Frequency increases or decreases as long as the digital input signals are
turned on
Multistep frequency selection: Up to 15 steps are selectable by a combination of digital input
signals (four kinds)
Link operation: Operation by RS485 (standard)
Program operation: Pattern operation by program
Jogging operation: Jogging operation by FWD, REV key or digital input signals.

Transistor output (4 signals): Running, frequency, arrival, frequency detection, overload early
warning, etc.
Relay output (2 signals): Alarm output (for any fault), multi-purpose output signals
Analog output (1 signal): Output frequency, output current, output voltage, output torque, power
consumption, etc.
Pulse output (1 signal): Output frequency, output current, output power, output torque, power
consumption, etc.
