Acceleration and deceleration Parameter
6 - 208
6.11.4 Shortest acceleration/deceleration (automatic acceleration/deceleration)
(Pr. 61 to Pr. 63, Pr. 292, Pr. 293)
The inverter operates in the same conditions as when appropriate values are set in each para-
meter even if acceleration/deceleration time and V/f pattern are not set. This function is useful
when you just want to operate, etc. without fine parameter setting.
When Pr. 570 Multiple rating setting
≠
"2", performing all parameter clear and inverter reset
changes the setting range (refer to section 6.7.5).
