DIP switches on top of the ZETA6104 set the amount of motor current during normal operations; this current is constant. To damp ringing, the active damping circuit can cause the ZETA6104 to produce up to twice as much current as is set by the DIP switches. The extra current is only applied during damping oscillations, and lasts a very brief time.

Electronic Viscosity (EV) 

The ZETA6104 uses closed-loop current control to develop and maintain precise currents in the motor phases. When EV is off, the current loops have a bandwidth of approximately 1000 Hz. Because this bandwidth is well beyond the knee of step motor speed-torque curves, the current loop dynamics do not limit the response of the motor. EV monitors motor velocity, and turns on below 3 rps. It “detunes” the current loop compensation values and brings the bandwidth down to 150 Hz. With this lower bandwidth, the drive electronics become “sluggish.” Ordinarily, when the rotor oscillates, it generates current in the motor’s coils; but with EV’s lower bandwidth, the drive’s electronics impede the flow of current caused by oscillations.
