A new pump sleep-mode function is available on the X200 and SJ200 Series microdrives. The function is implemented using external jumper wiring and the drive’s parameter settings and built-in PID control, logic, and timing functions. The sleep mode will stop the pump when no pumping is actually taking place, protecting the pump and saving energy.
