LOCAL/REMOTE select (setting : 17)

Select operation reference by the digital operator or by

the control circuit terminal.

LOCAL/REMOTE select is valid only during stop.

Open : Run by setting at run command selection (n02)

and frequency reference selection (n03).

Closed : Run by frequency reference and run command

from digital operator.

e.g. :

When the digital operator/control circuit terminal

selection setting is n02 = 1 and n03 = 2, 3 or 4

Open : Receives frequency reference (terminal FR,

RP) and run command (terminals S1 to S5 )

from control circuit terminal

Closed : Receives frequency reference (setting at n07)

and run command from digital operator.

Communication/control circuit terminal selection

(setting : 18)

Selects operation reference by communication or by

control circuit terminal. Communication/control circuit

terminal selection is valid only during stop.

Open : Run according to the setting at n02 and n03

(operation method selection).

Closed : Run by frequency reference and run command

from communication.

e.g. : When used for communication/control circuit

terminal selection, set n02 = 1 and n03 = 2, 3

or 4

Open : Receives frequency reference (terminal FR)

and run command (terminals S1 to S5 ) from

control circuit terminal

Closed: Receives frequency reference and run

command from communication

UP/DOWN command (setting : n39 = 34)

With the FWD (REV) run command entered,

accel/decel is enabled by inputting the UP or DOWN

signals to control circuit terminals S4 and S5 without

changing the frequency reference, so that operation can

be perfomed at the desired speed. When UP/DOWN

commands are specified by n39, any function set to

n38 becomes disabled; terminal S4 becomes an input

terminal for UP command and terminal S5 for DOWN

command.

* : Effective only when with option unit.

Time chart at UP/DOWN command input

U = UP (accelerating) status

D = DOWN (decelerating) status

H = HOLD (constant speed) status

U1 = UP status, clamping at upper limit speed

D1 = DOWN status, clamping at lower limit speed

Notes : • When UP/DOWN command is selected, the

upper limit speed is set regardless of

frequency reference.

Upper limit speed = Max. output frequency

(n09) × Frequency

reference upper limit

(n30) /100

• The lower limit speed is the largest value

among min. output frequency (n14) and

frequency reference lower limit (n31).

• When the FWD (REV) run command is input,

operation starts at the lower limit speed

without UP/DOWN command.

• When the jog command is input while running

by the UP/DOWN command, the jog

command has priority. The UP/DOWN

command can not be input together with

multi-step speed reference.

• By setting hold output frequency memory

selection (n62) to 1, the output frequency

during hold can be saved.

Setting at n62

Description

0 Output frequency during hold is not saved.

After 5 sec. of hold state, the output frequency

during hold is saved and the operation will

restart with the saved output frequency
