Elements You Need

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

1.(1) DMC-3425 or DMC-3415, (1) 37-pin cable (order Cable -37).

2.Servo motor(s) with encoders or stepper motors.

3.Appropriate motor drive - servo amp (Power Amplifier or AMP-1460) or stepper drive.

4.Power Supply for Amplifier

5.+5V, ±12V supply for DMC-3425

6.Communication CD from Galil

7.WSDK Servo Design Software (not necessary, but strongly recommended)

8.Interface Module ICM-1460 with screw-type terminals or integrated Interface Module/Amplifier, AMP-1460. (Note: An interconnect module is not necessary, but strongly recommended.) Also, the AMP-1460 only provides for 1 axis power amplification.

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

For servo motors, the drivers should accept an analog signal in the +/-10 Volt range as a command. The amplifier gain should be set so 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.

For step motors, the driver should accept step and direction signals. For start-up of a step motor system refer to Step 8c “Connecting Step Motors”.

The WSDK software is highly recommended for first time users of the DMC-3425. It provides step- by-step instructions for system connection, tuning and analysis.
