Operation mode selection (Pr. 79)

Pr. 79 "operation mode selection"
Used to select the operation mode of the inverter.
You can choose any of the operation modes: operation using external signals (external operation), operation
from the PU (FR-DU04/FR-PU04) (PU operation), combination of PU operation and external operation
(external/PU combined operation), and computer link operation (when the FR-A5NR option is used).

External operation mode
External/PU combined operation mode 1
Running frequency ..........Set from the PU (FR-DU04/FR-PU04) (direct setting, [UP/DOWN] key) or external
3
Start signal ......................External signal input (terminal STF, STR)
External/PU combined operation mode 2
4
Running frequency ..........External signal input (terminal 2, 4, 1, jog, multi-speed selection)
Start signal ......................Input from the PU (FR-DU04/FR-PU04) ([FWD] key, [REV] key)
Programmed operation mode
You can set 10 different operation starting times, rotation directions and running frequencies for each of three

groups.
Operation start. ............STF, timer reset. .......... STR
Group selection ............RH, RM, RL
Switch-over mode
6
Switch-over between PU operation, external operation and computer link operation (when the communication
option such as the FR-A5NR is used) modes can be done while running.
External operation mode (PU operation interlock)
7
X12 signal ON .................May be switched to PU operation mode (output stop during external operation)
X12 signal OFF ...............Switching to PU operation mode inhibited
Switching to other than external operation mode (disallowed during operation)
8 X16 signal ON ................Switched to external operation mode
X16 signal OFF ...............Switched to PU operation mode
Note: 1. Either "3" or "4" may be set to select the PU/external combined operation. These settings differ in
starting method.
( 1 ) Programmed operation
With this function, you can set 10 different operation starting times, rotation directions and running
frequencies individually for each of selected three groups to perform automatic operation under the
control of the internal elapsed time counting timer. For full information of this function, refer to the
explanations of Pr. 200 to Pr. 231.
