There are a number of Step-servo drives on the market today. Most of these drives are lacking features that are necessary for a reliable servo system that warns the control software that the motor is pushing too hard or over its limit. Instead these drives either Fault and remove power to the motor, causeing an uncontrolled motor, or fail to stop the controller at all (open loop).

The Viper 95 is rated at 12 amps continuous, 22 amps peak . An adjustable current control sets the drive for max average current to the motor protecting the motor from over current. The drive will also output a 'warn' error signal if the current outputs 80% of the max_current for 2 seconds or more.

The Viper drive has features such as soft error fault that will warn the controller to stop, if the motor is pushing too hard. Also a hard error trip-point can also be set to disable the motor if a severe over-current is detected. Other features are programable error warning range, setable from +-64 counts to +-2000 counts.

Viper drives have all the features that you need such as Differential encoder input for noise free operation on long cables, on board replaceable fuse, easy to interface error output, and a smooth silent control.

No more settleing for disposable economy drives that dither and whine when they are holding which can wear out ball screws and machine parts.

All viper drives are repairable. The Viper uses socketed driver chips for ease of replacement. Cheaper drives with Surface-mount drivers cannot be repaired.
