PIMag® Motion Controller for Magnetic Direct Drives
1 Axis, for 3-Phase Linear Motors with Average Power Consumption

C-891
 Maximum average current consumption
3A

 20-kHz control bandwidth
 USB interface for sending commands and
for configuration

 Digital inputs and outputs
 Optional analog input

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. Sinecommutated operation, field-oriented current control. Automatic detection of the motor phase. PID controller for position
and velocity. Servo update rate 20 kHz.

Encoder inputs

Differential signal transmission for digital (A/B) or analog (sin/cos) encoder signals. BiSS interface support for absolute
encoders. TTL 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: Detects the stages connected and simplifies configuration and
exchangeability. Supports direction-sensing reference point switches. Extensive software support, e.g., for LabVIEW, C, C++,
MATLAB, python. PIMikroMove user software.

Interfaces

USB and RS-232 for commanding. Digital inputs and outputs for automation. Analog input for direct control of the motor
current.
