8.5 Deceleration time
The DECEL. BRAKING parameter allows to define the deceleration rate depending
on 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:
