4.2.37 Operation mode selection (Pr. 79)

Pr. 79 "operation mode selection" Related parameters

Pr. 15 "jog frequency" Pr. 4 to Pr. 6, Pr. 24 to 27

(multi-speed operation)

Pr. 76 "alarm code output selection" Pr. 180 to Pr. 186

(input terminal function 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).

Pr. 79 Setting Function

0External operation mode at power-on

PU or external operation can be selected.

1PU operation mode

2External operation mode

External/PU combined operation mode 1

3Running frequency .....Set from the PU (FR-DU04/FR-PU04) (direct setting, key) or external

		signal input (multi-speed setting only)
	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)

Switch-over mode

6Switch-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)

7X12 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)

8X16 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.
