selected.
Use
Pr. 60 to
Pr. 63 for
selection
Reset
Reset the alarm output when the 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 second functions (acceleration
time, deceleration time, torque boost, base
frequency, electronic thermal relay function).
External thermal relay
input
Thermal relay contact input for use when the
inverter is stopped by the thermal relay.
Jog signal Jog operation mode selection
PID control valid Selection for exercising PID control
PU operation-external
operationswitching
Used to switch between PU operation and
external operation from outside the inverter.
