Acceleration/Deceleration Pattern - Mitsubishi Electric FR-CS84-012 Instruction Manual

5.4.2

Acceleration/deceleration pattern

The acceleration/deceleration pattern can be set according to the application.
Pr. Name
29 Acceleration/deceleration pattern
F100 selection
 Linear acceleration/deceleration (Pr.29 = "0" initial value)
• When the frequency is changed for acceleration, deceleration, etc. during inverter operation, the output frequency is
changed linearly (linear acceleration/deceleration) to reach the set frequency without straining the motor and inverter.
Linear acceleration/deceleration has a uniform frequency/time slope.
Setting value "0"
[Linear acceleration
/ deceleration]
Time
 S-pattern acceleration/deceleration B (Pr.29 = "2")
• This is useful for preventing collapsing stacks such as on a conveyor. S-pattern acceleration/deceleration B can reduce
the impact during acceleration/deceleration by accelerating/decelerating while maintaining an S-pattern from the present
frequency (f2) to the target frequency (f1).

NOTE
• When the RT signal turns ON during acceleration or deceleration with the S-pattern acceleration/deceleration B enabled, a
pattern of acceleration or deceleration changes to linear at the moment.
