Calculating acceleration
The maximum acceleration time T can be deduced from the step response.
U [V]
t [ms]
U
max
T
To calculate the acceleration increase T by 10%.
From this it follows that:
a =
v
T
max
. × 11
v
max
= velocity at U
max
a = acceleration
The step response must be investigated for all axes.
The acquired acceleration values are entered in MP1060.0 to MP1060.4.
After adjustment, switch off the supply voltage to the drive amplifiers.
This concludes the preparation of the drive amplifiers.
