The C-891 from PI is a digital motion controller for PIMag® three-phase linear motors. The controller offers extensive functionality in operational data recording, wave generation, ID chip support, and extensive software support. With one motor and one sensor channel, the device is capable of sine-commuted operation, field-oriented current control, and automated detection of the motor phase.
The C-891 is characterized by differential signal transmission for digital (A/B) or analog (sin/cos) encoder signals. This controller also has BiSS interface support for absolute encoders, as well as TTL signal inputs for limit and reference point switches. Additional features include a maximum average current consumption of 3 A, 20 kHz of control bandwidth, and USB interfacing for configuration and for sending commands.
