Acceleration time.
9.5 Braking time
The DECEL. BRAKING parameter allows to define the deceleration rate
depending on the final-speed setpoint. Deceleration time is evaluated differently
by software for speed steps greater or smaller than 100 Hz.
Case 1
(black trace in the graph):
Initial speed = 110 Hz
Final-speed setpoint = 10 Hz
DECEL. BRAKING = 2.5 s
The deceleration time results 2.5 s.
Case 2
(red trace in the graph):
Initial speed = 60 Hz
Final-speed setpoint = 10 Hz
DECEL. BRAKING = 2.5 s
The deceleration rate is re-scaled so that the deceleration time results
equal to DECEL. BRAKING, in this case 2.5 s.
Case 3
(green trace in the graph):
Initial speed = 150 Hz
Final-speed setpoint = 10 Hz
DECEL. BRAKING = 2.5 s
The deceleration time results:
