Selection of operation mode and operation location
Parameter
6 - 176
External operation mode (Pr. 79 = 0, 2)
Select the external operation mode when performing operation by providing a frequency setting
potentiometer, start switch, etc. externally and connecting them to the control circuit terminals
of the inverter.
Generally, parameter change cannot be performed from the operation panel in the External op-
eration mode. (Some parameters can be changed. Refer to Tab. 6-1 for the parameter list.)
When "0" or "2" is selected for Pr. 79, the inverter enters the external operation mode at power
on. (When using the network operation mode, refer to section 6.17.2).
If you don’t need to change the parameter settings frequently you can set the unit to external
mode permanently by setting Pr. 79 to "2". (If you need to change parameter settings frequently
external mode should be activated by setting Pr. 79 to "0". Then the frequency inverter will switch
to external mode automatically when the power is switched on but it can be switched to PU mode
by pressing the PU/EXT key. You can then make the parameter changes in PU mode and switch
back to external mode again afterwards by pressing PU/EXT again.)
The STF and STR signal are used as a start command, and the terminal 2, 4, multi-speed set-
ting, JOG signal, etc. are used as frequency setting.
