Int acc calc En Enabling of the calculation of the coil acceleration.
If enabled this function carries out the calculation of the angular acceleration inside the
drive. In this case it is necessary to set just the value of Time acc/dec min. If disabled,
it is necessary to set the parameters Line acc %, Line dec % , Fast stop % and Time
acc/dec min and to supply the corresponding status indication to the digital inputs.
Time acc/dec min Time in [s] corresponding to the lower acceleration, deceleration and fast deceleration time.
Acc/dec filter Filter in [ms] on the calculation of the acceleration inside the drive.
Line acc % Acceleration time as a percentage of Time acc/dec min.
Ex: Acceleration = line deceleration = 10s
Fast deceleration (fast stop) = 5s
Time acc/dec min = 5s
Line acc % = (5 / 10) x 100 = 50%
Line dec % Deceleration time as a percentage of Time Acc/dec min.
Ex: Acceleration = line deceleration = 10s
Fast deceleration (fast stop) = 5s
Time acc/dec min = 5s
Line dec % = (5 / 10) x 100 = 50%
Line fast stop % Fast deceleration time as a percentage of Time Acc/dec min.
Ex: Acceleration = line deceleration = 10s
Fast deceleration (fast stop) = 5s
Time acc/dec min = 5s
Line fast stop % = (5 / 5) x 100 = 100%
Line acc status Acceleration stating input .
Line dec status Deceleration stating input.
These two indications are combined with the drive digital outputs Acc state and Dec
state (see fig. 6.17.1).
