Click Start.

On the Gains tab, adjust current loop proportional gain (Cp):
 Set current loop integral gain (Ci) to zero.
 Raise or lower Cp to obtain desired step response. (Typically, little or no overshoot
with a 100 Hz, low-current square wave.) If the Cp value is too large, ringing may
occur. If the Cp value is too low, bandwidth decreases.
7
Adjust current loop integral gain (Ci) until desired settling time is obtained.
8
Press Stop to stop the function generator.
