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

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

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.
