C-891 is a 1-axis PIMag® motion controller for 3-phase linear motors, supporting sine-commutated operation and field-oriented current control with a 20 kHz servo frequency. It delivers up to 3 A rms per phase and operates from a 24 V external power supply with a maximum current consumption of 4.5 A. The unit includes USB and RS-232 interfaces for commanding, HD Sub-D 26 for motor connection, and a Sub-D 15 for sensor input. Digital inputs and outputs support TTL triggers and limit switches, with an additional analog input ranging from -10 to +10 V. It features overload, overcurrent, and overtemperature protection, a PID controller for position and velocity, and supports BiSS, differential A/B, and sin/cos encoder signals. Dimensions are 190 mm × 83 mm × 110 mm, and the mass is 1.0 kg. Operation occurs within a temperature range of 5 to 40 °C.
Digital motion controller for PIMag® linear motors
1 motor channel, 1 sensor channel. For three-phase linear motors, maximum current consumption 3A (rms) per phase. Sine-commuted operation, field-oriented current control. Automatic detection of the motor phase. PID controller for position and velocity. 20 kHz servo update rate
Encoder inputs
Differential signal transmission for digital (A/B) or analog (sin/cos) encoder signals. BiSS interface support for absolute encoders. TTL signal inputs for limit and reference point switches
Extensive functionality
Data recorder: Recording of operating data such as motor current, velocity, position or position error. Wave generator: Saves and outputs periodical motion profiles. ID chip support: Identifies the connected stages and simplifies configuration and exchangeability. Supports direction-sensing reference point switches. Extensive software support, for example for LabVIEW, dynamic libraries for Windows and Linux
Interfaces
USB 2.0, RS-232 commanding. Digital inputs and outputs for automation. Analog input for direct control of the motor current
