  •  One Preamp module (blue module CHAXN002V)                    
  • One Power Supply module (green module CHAXN004V)      
  • Two Output modules (red modules CHAXN001V)                    
  • One Motor Power Transformer – 750VA                                      
  • One low voltage Power Transformer – 75VA                                              
  • Two 15000MF/100v capacitors                                                          
  • New box with labor                                                                                               
  • One module bracket plate                                                                  
  • Cable form (inside box cable form).                                                                

This cable form provides connections between modules, transformers, capacitors, fuses and connectors.  This cable form provides communication with:  one 37 pin plastic connector (CNC, aux. power and main power); two 4 pin plastic motor connectors; two fuses for power transformers and ground connector. 

This servo drive provides drive enable for both axes simultaneously as default.  If the customer wants to enable the different axes at different times, then we need to make a customized servo drive.  Estop drive input is added.


This NEW PMW servo drive (modular) replaces old analog HL71B Lockformer HVAC ESAB, MG, Koike, and Advance Cutting Systems machine servo drive.  Upgrade of HL71B is available (install all of the electronics above in the customer’s old box).
