Acceleration/Deceleration Time (Pr. 7, Pr. 8, Pr. 20, Pr. 21, Pr. 44, Pr. 45) - Mitsubishi FR-E500 Series Instruction Manual

Note: 1. The multi-speeds can also be set in the PU or DeviceNet operation mode.
2. For 3-speed setting, if two or three speeds are simultaneously selected,
priority is given to the frequency setting of the lower signal.
3. Pr. 24 to Pr. 27 and Pr. 232 to Pr. 239 settings have no priority between
them.
4. The parameter values can be changed during operation.
5. When input terminal (DeviceNet input) assignment is changed using Pr. 180
to Pr. 183, the other functions may be affected. Check the functions of the
corresponding terminals (DeviceNet input) before making setting.
4.2.5 Acceleration/deceleration time (Pr. 7, Pr. 8, Pr. 20, Pr. 21,
Pr. 44, Pr. 45)

" Acceleration/deceleration time (Pr. 7, Pr. 8, Pr. 20, Pr. 21, Pr. 44, Pr. 45)

Pr. 7 "acceleration time"
Pr. 8 "deceleration time"
Pr. 20 "acceleration/deceleration reference frequency"
Pr. 21 "acceleration/deceleration time increments"
Pr. 44 "second acceleration/deceleration time"
Pr. 45 "second deceleration time"
Used to set motor acceleration/deceleration time.
Set a larger value for a slower speed increase/decrease or a smaller value for a faster
speed increase/decrease.
