IS215VPROH1BD Combustion engine module

Standard Servo Motor with +/- 10 Volt Command Signal The DMC-21x2/21x3 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.

Brushless Servo Motor with Sinusoidal Commutation

 The DMC-21x2/21x3 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 with a standard update rate of 1 millisecond*. For faster motors, please contact the factory. To simplify the wiring, the controller provides a one-time, automatic set-up procedure. When the controller has been properly configured, the brushless motor parameters may be saved in non-volatile memory.

The DMC-21x2/21x3 can control BLMs equipped 

with Hall sensors as well as without Hall sensors. If hall hall sensors are available, once the controller has been setup, the brushless motor parameters may be saved in non-volatile memory. In this case, the controller will automatically 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. *The update rate can be modified using the TM command. Please see the Command Reference for more details.
