Remote setting function

Pr.59 Remote function selection
Even if the operation panel is located away from the enclosure, you
can use contact signals to perform continuous variable-speed
operation, without using analog signals.
By merely setting this parameter, you can use the acceleration,
deceleration and setting clear functions of the motorized speed
setter (FR-FK).

Pr.60 Energy saving control selection
Without a fine parameter setting, the inverter automatically
performs energy saving operation.
This inverter is optimum for fan and pump applications
Valid only under V/F control and advanced magnetic flux vector
control.
Pr. 60 Setting
0 (initial value) Normal operation mode
Energy saving operation mode
In the energy saving operation mode, the inverter
4 automatically controls the output voltage to minimize
the inverter output voltage during a constant
operation.
When setting parameters, refer to the instruction manual (applied) and understand instructions.

Automatic acceleration/deceleration

Pr.61 Reference current
Pr.63 Reference value at deceleration
Pr.292 Automatic acceleration/deceleration
Pr.293 Acceleration/deceleration individual operation selection
The inverter automatically sets appropriate parameters for
operation.
The inverter operates in the same conditions as when appropriate
values are set in each parameter even if acceleration/deceleration
time and V/F pattern are not set. This operation mode is useful when
you just want to operate, etc. without fine parameter setting.
Even if automatic acceleration/deceleration has been selected,
inputting the jog, RT (second function selection) or X9 (third function
selection) signal during an inverter stop will switch to the normal
operation and give priority to jog operation, second function
selection or third function selection.
After automatic acceleration/deceleration operation has been
started, none of jog signal, RT signal and RT signal are accepted.
