6.23 Secondary acceleration/deceleration

6.23.1 Acceleration and deceleration patterns

 :Acceleration/deceleration pattern #1
 :S-pattern lower limit adjustment amount
 :S-pattern upper limit adjustment amount
・Function
These parameters are used to select an acceleration pattern and a deceleration pattern.

1)Linear acceleration and deceleration
Typical pattern of acceleration and
deceleration. This pattern is used in
most cases.
2) S-pattern acceleration/deceleration #1
This pattern is used in cases where
a motor needs to be speeded up to
or slowed down from a high-speed
range of over 60 Hz in a short time
or where there is a need to absorb
shocks at the start of acceleration
and deceleration. This pattern of
acceleration and deceleration is
suitable for the operation of
transportation and lifting equipment.
3) S-pattern acceleration/deceleration #2
In this pattern, the motor speeds up
slowly in weak-field areas where it
produces relatively small torque.
This pattern of acceleration and
deceleration is suitable for the
operation of high-speed spindles, etc.
