Output voltage regulation

Same as power line.

Output frequency

0.5 to 400Hz (0.1 to 80Hz setting when shipped); maximum
frequency range is 30 to 400Hz

Frequency setting

0.1Hz: Operating panel input; 0.03Hz: Analog input; 0.01Hz:

resolution

Input through computer interface (against a 60Hz)

Frequency accuracy

±0.5% (at 25°C; ±10°C) against the maximum frequency

Voltage/frequency

Either constant V/f or second-order nonlinear mode for variable

characteristics

torque. "Max voltage" frequency adjustment (25 to 400Hz), voltage
boost adjustment (0 to 30%), start-up frequency adjustment
(0 to 10Hz)

PWM carrier frequency

Adjusted in the range of 0.5kHz to 3kHz

switching

Operating

Acceleration/deceleration

0.1 to 6000 seconds, switching of acceleration time 1 or 2,

functions

time

selection of S-shaped 1 or 2, or selection of acceleration/
deceleration patterns

Electrical braking

G2+2010 to G2+430K; IGBT7 dynamic braking

DC injection braking Start-up frequency adjustment (0 to 10Hz),

braking voltage adjustment (0 to 20%),
braking time adjustment (0 to 5 seconds)

Forward or reverse run

Forward run when F-CC closed; reverse run when R-CC closed;
reverse run when both F-CC and R-CC closed; coasting stop
when ST-CC open; emergency coast stop by a command from
operating panel

Jogging run

Jogging run engaged when N.O. contact is closed. (adjustment
range 0 to 20Hz)

Multispeed run

By opening and closing different combinations of CC, SS1, SS2,
and SS3, the set speed or seven preset speeds can be selected.

Automatic fault latch reset

When a protective function is activated, the system checks main
circuit devices, and attempts the restart up to 5 times (deactivated
when shipped)

Soft stall

Sustains a run in overload mode (set at OFF when shipped)

Automatic restart

Smoothly recovers a normal run of a free-running motor utilizing
motor speed detection control.

Programmable RUN

Allows setting of 7 different patterns of automatic operation

patterns

Protection

Protective functions

Stall prevention, current limit, overcurrent, overvoltage, short-
circuit at load, load-end ground fault, undervoltage, momentary
power interrupt, electronic thermal overload, main circuit over-
current at start-up, load-end overcurrent at start-up, regenerative
discharge resistor overcurrent or overload, fin overheat, and
emergency stop. Provisions for external fault signal.

Electronic thermal

Standard motor/constant torque V/f motor switching, and

characteristics

electronic thermal stall prevention activating level adjustment

Reset

Resets inverter when N.O. contact is closed.
