Parameter
Acceleration and deceleration
FR-A700 EC
6 - 197
Change the setting range and increments of the acceleration/deceleration time (Pr. 21)
Use Pr. 21 to set the acceleration/deceleration time and minimum setting range.
Setting "0" (initial value) 0 to 3600s (minimum setting increments 0.1s)
Setting "1"
0 to 360s (minimum setting increments 0.01s)
Set multiple acceleration/deceleration time (RT signal, Pr. 44, Pr. 45, Pr. 110, Pr. 111)
●
Switching the parameter sets allows you to operate motors with different specifications and
capabilities with the frequency inverter.
●
Pr. 44 and Pr. 45 are valid when the RT signal is on, and Pr. 110 and Pr. 111 are valid when
the X9 signal is on. When both the RT and X9 are on, Pr. 110 and Pr. 111 are valid. For the
terminal used for X9 signal input, set "9" in any of Pr. 178 to Pr. 189 (input terminal function
selection) to assign the function.
●
When "9999" is set in Pr. 45 or Pr. 110, the deceleration time becomes equal to the second
acceleration time (Pr. 44, Pr. 111).
●
When Pr. 110 = "9999", third acceleration/deceleration time is invalid.
●
The RT (X9) signal acts as the second (third) function selection signal and makes the other
second (third) function valid.
●
The RT and X9 signal can be assigned to the input terminal using any of Pr. 178 to Pr. 189
(input terminal function selection).
b
CAUTION:
Changing the Pr. 21 setting changes the acceleration/deceleration setting (Pr. 7, Pr. 8,
Pr. 16, Pr. 44, Pr. 45, Pr. 110, Pr. 111, Pr. 264, Pr. 265).
(The Pr. 611 "Acceleration time at a restart" setting is not affected.)
Example:
When Pr. 21 = 0, setting "5.0" s in Pr. 7 and "1" in Pr. 21 automatically changes the
Pr. 7 setting to "0.5" s.
