Acceleration And Deceleration Time (Pr. 7, Pr. 8, Pr. 20, Pr. 21, Pr. 44, Pr. 45, Pr. 110, Pr. 111) - Mitsubishi Electric FR-V500 Instruction Manual

<Setting>
• Set the running speeds in the corresponding parameters.
Each speed can be set as desired in the range 0 to 3600r/min during inverter operation.
With any multi-speed setting parameter being read, press
In this case, press
SET
Pressing reflects the preset speed.

REMARKS
• Press when the FR-PU04V (option) is used.
WRITE
• Use Pr. 180 to Pr. 183 and Pr. 187 to assign the terminals used for signals RH, RM, RL, and REX. (*)
*Changing the terminal assignment using Pr. 180 to Pr. 183, Pr. 187 (input terminal function selection) may affect the other
functions. Please make setting after confirming the function of each terminal.
• The priorities of the external terminals for speed commands are as follows.
Jog > pulse train input (option FR-A5AP) > digital setting (option FR-A5AX) > multi-speed operation > PID > terminal 2
CAUTION
1. The multi-speed settings override the main speed (across terminals 2-5).
2. The multi-speeds can also be set in the PU or external operation mode.
3. For 3-speed setting, if two or more speeds are simultaneously selected, priority is given to the preset
speed of the lower signal. (RL > RM > RH)
4. Pr. 24 to Pr. 27 and Pr. 232 to Pr. 239 settings have no priority between them.
5. The settings can also be changed during operation.
6. When the jog signal is used with multi-speed signals, the jog signal has priority.

3.3.5 Acceleration and deceleration time
(Pr. 7, Pr. 8, Pr. 20, Pr. 21, Pr. 44, Pr. 45, Pr. 110, Pr. 111
Set the acceleration/deceleration time of the motor
during speed control and position control by
parameter setting.
Set a larger value for a slower speed increase/
decrease or a smaller value for a faster speed
increase/decrease.
Under torque control, the speed limit value varies
with the acceleration/deceleration time.
