Notes regarding example 2
•
Braking with the set ramp until the motor reaches a standstill
is only possible if the speed value 0 (zero) is preset while the
motor is in motion (range [R]).
•
If the enable or direction of rotation is set to LOW, the motor
stalls abruptly – regardless of the ramp.
•
The ramp can be modified during operation. It is therefore
possible to set different acceleration and braking times (e.g.
acceleration in 6 seconds, braking in 3 seconds).
