Motor programming + spindle speeds and Reverse:

  • The motor speed can be programmed to operate in any range chosen by the user.
    Between 300 and 3,000 RPM's.
    Note: Settings are limited to 10 RPM intervals.
  • The full range of speed (RPM's) can also be controlled with just the speed control knob.
  • Speed control programming only requires a few easy steps.
  • Reverse is simple, just hold the yellow button for a few seconds.
  • Programming includes the ability to set bottom and top RPM range separately. In other words you can program the system to run the spindle at any speed or range of speeds you choose (see below).
    Slowest speed achievable: Motor 100 RPM. (Below 300 is not recommended).
    Highest speed: 3,000 RPM.
  • Soft start is programmable and will be set as soft as possible when you receive this motor. This program is very effective in reducing drive belt wear etc.
  • Braking strength is also programmable and will be set as low as possible. Personally I wish I could set it lower.
  • Self diagnostics with fault code chart and programming instructions are available on our web site.
  • Safe turn on system where the speed control knob must be in the full counter clockwise (stop) position when turned on. When turned on the self diagnostic system checks for faults and will not allow the motor to run until the speed control knob is turned all the way to stop first.
  • Remote stop/start without self diognostics step above is possible. This is a use at your own risk
    function made possible for those wishing to instal a trigger, travel or CNC switch.
  • Use at your own risk. Our liability is limited to the purchase price of this item.
