PMDX-107 Isolated Speed Control

Model PMDX-107

Isolated Speed Control

 

Click on image for larger view.
 

The PMDX-107 is an basic speed control with isolated analog output for use with PMDX boards that support an option card interface, such as the PMDX-125 and PMDX-132. It includes low-power SSR's (solid state relays) for a spindle control outputs.

  • Used as a daughter board on the PMDX-132, the PMDX-125, and future boards with option connector
  • Sets spindle speed using PWM from CNC control software
  • Works with any system that can supply a 100 Hz to 10 KHz PWM signal. 
  • Needs fewer signals because PWM signal is used for both speed, and On/Off (absence of pulses stops motor) 
  • Works with 5 volt analog inputs, 10 volt analog inputs, and most potentiometer interfaces up to 15 volts
  • Provides one isolated solid state switch to turn spindle on and off via VFD control inputs or a small relay
  • Provides one isolated solid state switch to control direction via VFD control inputs or a small relay
  • Can directly control high current relay on PMDX-125 where mains switching must be used for safe spindle run/stop control, e.g. DC motor controllers like the KBIC series used by Sherline.
  • Fully isolated interface can be used with non-isolating VFD's and motor drivers
  • Operates from a single 5 volt power supply or receives power from option jack on PMDX boards
  • Has on board inverter for isolated power needs
  • Provides switchable filter to limit speed ramp rate for sensitive motor drivers, reduces probability of blown fuses
  • Provides safety interlock for "charge pump OK" input monitoring and detection of missing PWM
  • Provides speed calibration pot for setting maximum speed
  • Status LED’s for POWER, PWM active, FWD/Run, and REV/Dir.
  • Manual run/stop, speed, and direction control are possible using an external pot, relays, and/or switches
