PDS is pleased to provide a redundant drive system that will seamlessly transfer from a running drive to a standby drives. The purpose of the Drive Transfer System is to provide a redundant Variable Frequency Drive (VFD) source with automatic transfer control for critical loads. Common uses include Boiler Draft Fans, Extruders, Polymer Pumps, etc. The system includes two Variable Frequency Drive cabinets and one Transfer Cabinet with power and control components to provide operations of a fault transfer scheme from the running drive to the standby drive. The incoming power for each drive cabinet can be provided from a separate power source to provide power redundancy. The Transfer system can be initiated by automatic transfer or by a manual transfer scheme.

Power Ride Thru Systems

PDS engineering staff has plenty of experience when it comes to Power Ride-Thru. In most applications, customers require a 50%  Voltage dip ride-thru for 30 cycles, in other cases protection is need for a complete 100% loss of power for critical applications. In either case PDS can supply drives and systems that can meet these requirements. We can provide these solutions using drives with special ride-thru capacities, implement a Common DC Busing Platform with Capacitor Ride-Thru, Battery Back-up Systems or by adding DC Voltage regulator.  We have years of experience in designing Power supplies and converting AC power to a Common DC Bus platforms for those needed machine upgrades.

Drive Retrofit Kit

Retrofits 3

PDS is pleased to provide a transparent solution to replace vintage Z200, A200, A500, A024, A044 and E500 series drives with a retrofit kit that will functional replace vintage drives without modifying existing communications with DCS, PC or PLC. The retrofit kits use the latest “State of the Art” Mitsubishi FR-A700 or E700 Series Drives. The direct replacement provides operation of existing functions including communications interface that translates protocol from the DCS, PC or PLC so parameters and mode information is processed properly. This allows the replacement of single functioning drives in a communications loop without having to change the existing communication network.

Each replacement could include the following:

  • Mitsubishi Drive A700 or E700 Series
  • Adapter Plate
  • Communications Interface Board
  • Communication Cable
  • Bezel for Door mounted parameter Unit
  • FR-PU07 Parameter Unit
  • Parameter Unit Cable

These retrofits kits can be also used to replace other manufacturer’s drives. Gives a call and we can provide a proposal for an easy drive retrofit.
