ABB 3BSE018104R1 Channel intelligent module

Brushless Servo Motor with Sinusoidal Commutation The DMC-18x2 can provide sinusoidal commutation for brushless motors (BLM). In this configuration, the controller generates two sinusoidal signals for connection with amplifiers specifically designed for this purpose. Note: The task of generating sinusoidal commutation may be accomplished in the brushless motor amplifier. If the amplifier generates the sinusoidal commutation signals, only a single command signal is required and the controller should be configured for a standard servo motor (described above). Sinusoidal commutation in the controller can be used with linear and rotary BLMs. However, the motor velocity should be limited such that a magnetic cycle lasts at least 6 milliseconds*. For faster motors, please contact the factory.

The controller provides a one-time

automatic set-up procedure. The parameters determined by this procedure can then be saved in non-volatile memory to be used whenever the system is powered on. The DMC-18x2 can control BLMs equipped with Hall sensors as well as without Hall sensors. If hall sensors are available, once the controller has been setup, the controller will estimate the commutation phase upon reset. This allows the motor to function immediately upon power up. The hall effect sensors also provide a method for setting the precise commutation phase. Chapter 2 describes the proper connection and procedure for using sinusoidal commutation of brushless motors. * 6 Milliseconds per magnetic cycle assumes a servo update of 1 msec (default rate).

Standard Servo Motors with +/- 10 Volt Command Signal 

The DMC-18x2 achieves superior precision through use of a 16-bit motor command output DAC and a sophisticated PID filter that features velocity and acceleration feedforward, an extra pole filter and integration limits. The controller is configured by the factory for standard servo motor operation. In this configuration, the controller provides an analog signal (+/- 10Volt) to connect to a servo amplifier. This connection is described in Chapter 2.
