ABB DSRB0110 3ASD510001C2 Sequence control module

Connect Hall Sensors if available. Hall sensors are only used with sinusoidal commutation and are not necessary for proper operation. The use of hall sensors allows the controller to automatically estimate the commutation phase upon reset and also provides the controller the ability to set a more precise commutation phase. Without hall sensors, the commutation phase must be determined manually. Each set of sensors must use inputs that are in consecutive order. The input lines are specified with the command, BI. For example, if the Hall sensors of the Z axis are connected to inputs 6, 7 and 8, use the instruction: BI ,, 6

Connect Standard Servo Motors

 The following discussion applies to connecting the DMC-18x2 controller to standard servo motor amplifiers: The motor and the amplifier may be configured in the torque or the velocity mode. In the torque mode, the amplifier gain should be such that a 10 Volt signal generates the maximum required current. In the velocity mode, a command signal of 10 Volts should run the motor at the maximum required speed. Step by step directions on servo system setup are also included on the WSDK (Windows Servo Design Kit) software offered by Galil. See section on WSDK for more details.

 Check the Polarity of the Feedback Loop

 It is assumed that the motor and amplifier are connected together and that the encoder is operating correctly (Step B). Before connecting the motor amplifiers to the controller, read the following discussion on setting Error Limits and Torque Limits. Note that this discussion only uses the X axis as an example. Step B. Set the Error Limit as a Safety Precaution Usually, there is uncertainty about the correct polarity of the feedback. The wrong polarity causes the motor to run away from the starting position. Using a terminal program, such as DMCTERM, the following parameters can be given to avoid system damage: Input the commands: ER 2000Sets error limit on the X axis to be 2000 encoder counts
