This document provides hardware connection information for the Acroloop ACR8000 motion controller. The ACR8000 is a floating point DSP-based 8 axis motion controller. It has onboard hardware to read up to eight incremental encoders and supply precision 16-bit analog for eight servo amplifiers.

Chapter Overview Description: This chapter contains diagrams of the jumpers and connectors on the ACR8000 mother and daughter boards. Before optically isolated digital inputs and outputs can be used, the card must be connected to an external 24 volt DC power supply. This connection is made at the PWR1 connector and is fused onboard at 3 amps to protect the controller card.
Figure 1.1 Address select switch The ACR8000 can receive and transmit data through I/O ports on a PC BUS. The addresses of these ports are selectable using SW1 on the ACR8000 motherboard. The data port is used to both transmit and receive. Both the transmit and receive channels are connected to 512 byte First In / First Out (FIFO) hardware buffers.

Figure 1.3 PC BUS interrupt jumper The ACR8000 can be instructed to interrupt a PC host through the parallel bus by issuing a SET 112 command in immediate mode or from within a program. Interrupt driven software at the host level is an advanced topic and should only be attempted by someone with a thorough knowledge of interrupt driven code.
Encoder Pull-up Select (JS21..JS28) Figure 1.4 Encoder pull-up jumpers The ACR8000 is capable of handling various types of incremental open-collector and line driver encoders. Care must be taken to setup each channel to match the encoder type as described below:...
Motherboard Jumpers Encoder Pull-up Select (continued) Line Driver Encoders: When using line driver (or balanced pair) encoders, the corresponding resistor pack should be removed from its socket. Leaving the resistor pack in can cause faulty encoder operation and possibly cause severe encoder damage. It does not matter what pull-up voltage is selected when the resistor pack is removed.

ACR8000 Expansion I/O Board (Optional) The I/O for the ACR8000 expansion I/O cards is mapped into the previously reserved bits 256 through 511. There are also four new bits (Bits 116 thru 119, ACR2000/ACR8000 User’s Guide, Miscellaneous Output Flags) which act as card enable control bits.
