Acceleration/Deceleration Time (Pr. 7 , Pr. 8 , Pr. 20 , Pr. 44 , Pr. 45 ) - Mitsubishi Electric FR-S520E Series Instruction Manual

Explanation of functions (parameters)
CAUTION
1. The multi-speed settings override the main speeds (across terminals 2-5, 4-
5, setting dial). When the multi-speed settings and setting dial are used in
the combined operation mode (Pr. 79 = 3), the multi-speed settings have
precedence.
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 set frequency of the lower signal.
4. Pr. 24 to Pr. 27 and Pr. 80 to Pr. 87 settings have no priority between them.
5. The parameter values can be changed during operation.
6. When using this function with the jog signal, the jog signal has precedence.
REMARKS
The frequency-set external terminals have the following priority:
Jog > multi-speed operation > AU (terminal 4) > terminal 2
