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
