Control specifications
Control system
Selectable between Soft-PWM control and high carrier
frequency PWM control, V/F control or automatic torque
boost control are selectable.
Output frequency range
0.5 to 120Hz (starting frequency variable between 0 and
60Hz)
Frequency setting resolution
5VDC input: 1/500 of max. set frequency, 10VDC,
4 to 20mADC input: 1/1000 of max. set frequency
Digital input: 0.1Hz (less than 100Hz), 1Hz (100Hz or higher)
Frequency accuracy
Analog input: Within ±1% of max. output frequency
(25
°C±10°C)
Digital input: Within ±0.5% of set output frequency (when set
by the setting dial)
Starting torque 150% (at 5Hz) during automatic torque boost control

Alarm reset
Used to reset alarm output provided when
protective function is activated.
Multi-speed selection
Up to 15 speeds can be selected. (Each speed
can be set between 0 and 120Hz, running speed
can be changed during operation from the
operation panel.)
Second function selection
Used to select second functions (acceleration
time, deceleration time, torque boost, base
frequency, electronic thermal relay function).
Output stop
Instantaneous shut-off of inverter output
(frequency, voltage)
Current input selection
Used to select frequency setting signal 4 to 20
mA (terminal 4).
External thermal relay
input
Thermal relay contact input for use when the
inverter is stopped by the external thermal relay.
Jog signal Jog operation mode selection
PID control valid Selection for exercising PID control
PU operation /external
operation switchover
Used to switch between PU operation and
external operation from outside the inverter.
