60Hz)
Frequency setting resolution
5VDC input: 1/500 of max. set frequency, 10V, 4 to
20mADC input: 1/1000 of max. set frequency. Digital input:
0.1Hz (less than 100Hz), 1Hz (100Hz or higher)

automatic self-holding input (3-wire input) can
be selected.
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 control panel.)
Second function selection
Used to select second functions (acceleration
time, deceleration time, torque boost, base
frequency, electronic overcurrent protection).
Output stop
Instantaneous shut-off of inverter output
(frequency, voltage).
Current input selection
Used to select input of frequency setting signal
4 to 20mADC (terminal 4).
External thermal relay
input Thermal relay contact input for use when the
inverter is stopped by the external thermal relay.
