1 Axis, for 3-Phase Linear Motors with Average Power Consumption
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-
commutated 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.
