Elements You Need; Nstalling The Dmc-18 2 - Galil Motion Control DMC-18 2 Series User Manual

Elements You Need

Before you start, you must get all the necessary system elements. These include:
1. DMC-1812, 1822, 1832, or DMC-1842 Motion Controller, (1) 100-pin cable, and (1)
2. Servo Motors with Optical Encoder (one per axis) or Stepper Motors.
3. Power Amplifiers.
4. Power Supply for Amplifiers.
5. PC (Personal Computer - PCI bus).
6. Communications Software – DMCTERM, DMCWIN32, or WSDK32 (On Galil Software
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 peak motor 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 "Connecting Step Motors" on page 20.
The WSDK software is highly recommended for first time users of the DMC-18x2. It provides step-
by-step instructions for system setup, tuning and analysis.
Installing the DMC-18x2
Installation of a complete, operational DMC-18x2 system consists of 9 steps.
Step 1. Determine overall motor configuration.
Step 2. Install Jumpers on the DMC-18x2.
Step 3. Install the communications software.
Step 4. Install the DMC-18x2 in the PC.
Step 5. Establish communications with the Galil communication software.
Step 6. Determine the axes to be used for sinusoidal commutation.
Step 7. Make connections to amplifier and encoder.
Step 8a. Connect standard servo motors.
Step 8b. Connect sinusoidal commutation motors.
