Acceleration and deceleration times T
Each acceleration or deceleration time refers to a speed change from 0 to n
(C011). The times T and T

( Additonal acceleration and deceleration times
Alternaltively to the acceleration and deceleration times under C012 and C013,
additional T and T times can be retrieved from the memory, for instance, to

change the drive acceleration from a certain speed on.
Programming of additional acceleration and deceleration times
Set the additional T times in two steps. The selection under C100 is valid for a pair

of acceleration and deceleration times:
( Select additional acceleration/deceleration times under C100.
( Enter the required acceleration time under C101, and the deceleration time
under C103.
For several additional T
