bursts.

Using the target torque and torque constant from the example above the current draw can

be checked, as shown:

0.3531 Nm

= 5.0443 A

0.07 Nm

A

The resultant current, 5.0443A, is below the 7A continuous current rating of the drive, and

well below the peak current rating of 14A. It is possible for the drive to maintain a current of 7A

indefinitely, and peak up to 14A for up to two seconds continuously. Values between 7A and

14A may be held proportionally long.
