The EDC TDC VRP XDC PMC controllers are obsolete and no longer available nor are accessories. They've been obsolete for over 10 years and will need to be replaced. They are not repairable and haven't been for over 10 years and parts are not available. 

Depending upon the application, the ACR7000 series controller platforms could be considered as a replacement, or the Compax3 series servo drive/controllers. 

The ACR7000 uses AcroBasic programming language. With standard analog or step&direction drives, the maximum number of axes is 8.

Communication: Ethernet TCP/IP and Ethernet/IP (scanner/adapter), Ethernet/IP for interface to Allen-Bradley PLCs
Software: Parker Motion Manager
Onboard I/O:
2 or 4 axes: 31 inputs, 4 outputs
6 or 8 axes: 62 inputs, 8 outputs
Expansion I/O with Parker I/O using Ethernet/IP
Interact Xpress platform allows quick programming of HMI to the ACR7000 communication drivers to further interface to other PLCs. There are several samples within our knowledgebase of Xpress with ACR7000 to jumpstart your work.

 

The Compax3 T40 is a servo drive/controller and uses the IEC61131-3 language (Ladder Logic LD, Structured Text ST, Continuous Flow Chart CFC, Sequential Flow Chart SFC, Function Block Diagram FBD). It's available in single axis C3S, high powered C3H or multi-axis C3M configurations. Each drive has dedicated encoder/resolver feedback for motor control in addition to secondary feedback input (incremental or absolute, quadrature or SSI).

 

 
General details on the Pemstar controllers (MTS Automation EDC TDC VRP PMC) are available below:

EDC100 (445115-04) and TDC100 (429577-04)
The controllers were single axis only, capable of using the feedback of an encoder (EDC) or a Temposonics® transducer (TDC) LH and II position sensors

EDC200 (445114-04) and the TDC200 (429576-04). These products are a two axis controller.

The XDC offered 1 to 28 axes of control, 54 inputs and
37 outputs, stepper (open or closed loop), servo (standard single feedback closed loop or dual-loop, encoder or Temposonics® transducer).

XDC700 or XDC710:

  • 5 dedicated outputs

  • 18 dedicated inputs

  • 32 input/output points which can be configured as inputs or outputs

  • 4 high-speed sensor inputs are provided

XDC720

  • 56 input/output points which can be used as inputs or outputs

  • 4 high-speed sensor inputs are provided

General Features:

  • RS 232 or RS 485, Optional keypad

  • Programs in the two-axis model can run two axes independently, interlocked, or in ratio to one another

  • Multiple controllers can be coordinated through digital I/O or multi-drop serial communications

  • Programs contain readable statements like WAIT, REPEAT, and RAMP

  • Up to eight programs for each axis can be stored internally

  • Battery-backed RAM allows user programs and setup parameters to be saved while power is off

  • LCD screen, displaying 4 lines of 16 characters each

The VRP was the same controller with special firmware for rotary knife application.

As this is a major upgrade involving new programming, you may contact your local Parker Automation Technology Center distributor. Local ATCs are familiar with the ACR7000 and Compax3 and can offer programming services or can recommend local integrators. 

If this is part of a machine, your machine builder may also be a resource to discuss upgrades/replacements and they may have engineered & programmed replacements.

 

 

The PMC10 and PMC20 were sold by Parker Hydraulics and were the same as the TDC100 and TDC200.

Common part replacement:

419233-01 This was the keypad assembly.

485328-01 This was the touchpad replacement for the keypad.
