Acceleration/Deceleration Settings
6-66
( 1 ) Acceleration/Deceleration Units and Speed Changes Over Time
The Linear Acceleration Time (OL
36) and Linear Deceleration Time (OL
38) settings
change depending on the Acceleration/Deceleration Unit (OW
03) setting as shown in the fol-
lowing figure.

When the Acceleration/Deceleration Unit (OW
03, Bits 4 to 7) Set to 0: Refer-
ence Unit/s

Linear Acceleration and Linear Deceleration Time settings are handled as the linear acceleration
rate and linear deceleration rate.
■
When the Acceleration/Deceleration Unit (OW
03, Bits 4 to 7) Set to 1: ms
Linear Acceleration Time is handled as the linear acceleration time constant required to reach
rated speed from zero using linear acceleration. Linear Deceleration Time is handled as the linear
deceleration time constant required to reach zero from the rated speed using linear deceleration.
