Change The Acceleration/Deceleration Time (Pr. 7, Pr. 8) - Mitsubishi Electric FR-E700 Instruction Manual

Basic settings
5.1.5

Change the acceleration/deceleration time (Pr. 7, Pr. 8)

Set in Pr. 7 "Acceleration time" a larger value for a slower speed increase and a smaller value for a faster
speed increase.
Set in Pr. 8 "Deceleration time" a larger value for a slower speed decrease and a smaller value for a fast-
er speed decrease.

No.
7
Acceleration time
8
Deceleration time
Depends on the Pr. 21 "Acceleration/deceleration time increments" setting. The initial value for
the setting range is "0 to 3600 s" and setting increments is "0.1 s".
NOTE
Too short acceleration/deceleration times may lead to an inverter shutoff with error message
(E.THT, E.THM, E.OCT, E.OVT ...).
Example Change the Pr. 7 "Acceleration time" setting from "5 s" to "10 s".
