STANDARD SPECIFICATIONS
Sinusoidal PWM control
Same as power line.
0.0 to 120.0 Hz (0.0 to 60 Hz setting when shipped)
0.1Hz: Operating panel input; 0.03 Hz: Analog input;
0.01Hz: Input through computer interface
±0.5% (at 25°C; ±10°C) against the maximum frequency
Second-order nonlinear mode for variable torque.
"Max voltage" frequency adjustment (30 to 120 Hz), torque
boost adjustment (0 to 30 %), start-up frequency adjustment
(0 to 10 Hz)
3k ohms potentiometer (a 1k to 10k ohms-rated potentiometer can
be connected). 0 to 10 Vdc (input impedance: 30k ohms), 0 to
5 Vdc (15k ohms), 4 to 20 mAdc (250 ohms)
Determines the rate of change of frequency out, when compared
to rate of change of speed reference signal.
3-points with selectable jump frequency and bandwidth
Upper limit frequency: 0.0 Hz to maximum frequency
Lower limit frequency: 0.0 Hz to upper limit frequency
Adjusted in the range of .5 kHz to 3.0 kHz
3 to 1200 seconds, switching of acceleration time 1 or 2,
selection of S-shaped 1 or 2, or selection of acceleration/
deceleration patterns
DC injection braking Start-up frequency adjustment (0 to 10 Hz),
braking voltage adjustment (0 to 20 %),
braking time adjustment (0 to 5 seconds)
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 engaged when N.O. contact is closed. (adjustment
range 0.0 to 20.0 Hz)
By opening and closing different combinations of CC, SS1, SS2,
and SS3, the set speed or seven preset speeds can be selected.
When a protective function is activated, the system checks main
circuit devices, and attempts the restart up to 5 times (activated
when shipped).
Sustains a run in overload mode (set at ON when shipped)
Smoothly recovers a normal run of a free-running motor utilizing
motor speed detection control.
Allows setting of 7 different patterns of automatic operation
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, cooling
fin overheat, and emergency stop. Provisions for external
fault signal.
Standard motor/constant torque V/f motor switching, and
electronic thermal stall prevention activating level adjustment
Resets inverter when N.O. contact is closed.
