Frequency setting by external terminals
4.6.3
Remote setting function (Pr. 59)
The above parameter can be set when Pr. 160 Extended function display selection = "0". (Refer to page 156)
* External running frequency (other than multi-speed) or PU running frequency
NOTE
When Pr. 29 Acceleration/deceleration pattern selection = "1" (S-pattern acceleration/deceleration A), the acceleration/
deceleration time is the period of time required to reach Pr. 3 Base frequency.
The Pr. 15 setting should be equal to or higher than the Pr. 13 Starting frequency.
The JOG signal can be assigned to the input terminal using any of Pr. 178 to Pr. 182 (input terminal function selection).
When terminal assignment is changed, the other functions may be affected. Please make setting after confirming the
function of each terminal.
During Jog operation, the second acceleration/deceleration via the RT signal cannot be selected. (The other second
functions are valid. (Refer to page 227))
When Pr. 79 Operation mode selection = "4", pressing
of the operation panel and
/
of the parameter unit
(FR-PU04/FR-PU07) starts the inverter and pressing
stops the inverter.
This function is invalid when Pr. 79 = "3".
