When Bits 4 to 7 in OW
The setting of OL
36 is treated as the linear acceleration time constant, or the time
required to reach the rated speed from a speed of zero using linear acceleration. The setting of
OL
38 is treated as the linear deceleration time constant, or the time required to reach a
speed of zero from the rated speed using linear deceleration.
