VME Connector

Master Reset & UPGRD jumpers

INCOM & LSCOM jumpers. Used for bypassing opto-isolation for the limit, home, and abort switches and the digital inputs IN1 - IN8. See section “Bypassing Opto-Isolation”, Chap3.

Jumpers used for configuring stepper motor operation on axes 1-4.

IRQ jumper. Interrupts may be set on IRQ 1–7.

Address jumpers. The base address of the controller is FFF0. Address jumpers A4-A15 may be set as offsets to that address

IAD1-IAD4 allows transfer of the IRQ between the controller and host. This three bit binary combination must be set equal to the IRQ line chosen.

Note: Above schematics are for most current controller revision. For older revision boards, please refer to Appendix.

Elements You Need

Before you start, you must get all the necessary system elements. These include:

1.DMC-13X8, (1) 100-pin cable and (1) ICM-1900. Connection to the extended I/O can be made through the IOM-1964 opto-isolation module. Using the IOM-1964 requires (1) IOM-1964, (1) CB-50-100 and (1) 100 pin cable.

2.Servo motors with Optical Encoder (one per axis) or step motors.

3.Power Amplifiers.

4.Power Supply for Amplifiers.

5.VME host and user interface.

The motors may be servo (brush type or brushless) or steppers. The amplifiers should be suitable for the motor and may be linear or pulse-width-modulated. An amplifier may have current feedback, voltage feedback or velocity feedback.

For servo motors in current mode, the amplifiers should accept an analog signal in the +/-10 Volt range as a command. The amplifier gain should be set such that a +10V command will generate the maximum required current. For example, if the motor peak current is 10A, the amplifier gain should be 1 A/V. For velocity mode amplifiers, a command signal of 10 Volts should run the motor at the maximum required speed. Set the velocity gain so that an input signal of 10V, runs the motor at the maximum required speed.

For step motors, the amplifiers should accept step and direction signals. For start-up of a step motor system refer to Step 7c “Connecting Step Motors”.
