•Touse n11(frequencyreference1) and n12 (frequency reference 2), set “4”(multi-step
speed command 1) in one of n06 to n08 (multi-function input selection 1 to 3).
•To use n11 to n14 (frequency references 1 to 4), set “4” (multi-step speed command 1)
and “5” (multi-step speed command 2) in two of n06 to n08 (multi-function input selec-
tion 1 to 3).
•To use n11to n18(frequency references 1 to 8), set “4” (multi-step speed command 1),
“5”(multi-step speedcommand2),and“6”(multi-stepspeedcommand 3)inn06 ton08
(multi-function input selection 1 to 3).
•When “0” (override) is set in n06, n18 (frequency reference 8) is set to the basic fre-
quency (100% frequency reference).

•These constants are used to set acceleration time (required to increase the output fre-
quency from the stopped state to the maximum frequency) and deceleration time (re-
quired to decrease the output frequency from the maximum frequency to the stopped
state).
(Set the maximum frequency in n24.)
•The unit of setting is as follows:
0.0 to 99.9 (seconds): 0.1 (second)
100 to 999 (seconds): 1 (second)
•Acceleration and deceleration times can be changed even during operation. If, for ex-
ample, acceleration time is to changed, light the ACC indicator with the Mode Key first,
press the Increment or Decrement Key to change the value, then press the Enter Key.
Deceleration time can be also changed in the same way. (Light the DEC indicator be-
fore changing the deceleration time.)
