Installing The Dmc-14Xx Controller; Step 1. Determine Overall Motor Configuration - Galil Motion Control DMC-14 5 Series Manual

For the DMC-1416, the internal amplifier is a 20V to 60V PWM amplifier in either a brush or
brushless configuration, so only a brush or brushless DC servo motor may be used.
The WSDK software is highly recommended for first time users of the DMC-14XX. It provides step-
by-step instructions for system connection, tuning and analysis.

Installing the DMC-14XX Controller

Installation of a complete, operational DMC-14XX system consists of 9 steps.

Step 1. Determine overall motor configuration.

Step 2. Configuring jumpers on the DMC-14XX.
Step 3. Connect the DC power supply and serial cable to the DMC-14XX.
Step 4. Install the communications software.
Step 5. Establish communications between the DMC-14XX and the host PC.
Step 6. Set-up axis for sinusoidal commutation (DMC-1415 only).
Step 7. Make connections to amplifier and encoder.
Step 8a. Connect standard servo motor.
Step 8b. Connect brushless motor for sinusoidal commutation. (DMC-1415 only)
Step 8c. Connect step motor.
Step 8d. Connect brush or brushless servo motor to DMC-1416
Step 9. Tune servo system.
Step 1. Determine Overall Motor Configuration
Before setting up the motion control system, the user must determine the desired motor configuration.
The DMC-141X can control standard brush or brushless servo motors, sinusoidally commutated
brushless motors or stepper motors. For control of other types of actuators, such as hydraulics, please
contact Galil. The following configuration information is necessary to determine the proper motor
configuration:
Standard Servo Motor Operation:
The DMC-141X has been setup by the factory for standard servo motor operation providing an analog
command signal of +/- 10 volt. The position of the jumpers at JP3 determines the type of output the
controllers will provide, analog motor command or PWM output. The installation of these jumpers is
discussed in the section "Configuring Jumpers on the DMC-14XX". Figure 2.3 shows how the
jumpers are configured for the standard output mode.
The DMC-14XX controller will output the analog command signal to either brush or brushless servo
amplifiers. Please note that if the brushless amplifier provides the sinusoidal commutation, the
standard servo motor operation from the controller will be used. If the commutation is to be performed
by the controller, please see below.
The DMC-1416 provides an internal PWM amplifier for connection directly to a brush or brushless
motor. Either the brush or brushless amplifier must be specified at the time of purchase.
Sinusoidal Commutation:
Please consult the factory before operating with sinusoidal commutation.
Sinusoidal commutation is configured through a single software command, BA. This setting causes
the controller to reconfigure the control axis to output two commutated phases. The DMC-1415
requires two DAC outputs for a single axis of commutation. Therefore, sinusoidal commutation is not
