Digital input
Entered from operation panel
Forward and reverse rotation, start signal
automatic self-holding input (3-wire input) can be
Reset the alarm output when the protective
function is activated.
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.)
Used to select second functions (acceleration
time, deceleration time, torque boost, base
frequency, electronic thermal relay function).
Instantaneous shut-off of inverter output
(frequency, voltage)
Used to select frequency setting signal 4 to 20
mA (terminal 4).
Thermal relay contact input for use when the
inverter is stopped by the external thermal relay.
Jog operation mode selection
Selection for exercising PID control
Used to switch between PU operation and
external operation from outside the inverter.
