PID motion controller / servo / USB

Digital motion controller for PIMag?Voice Coil drives
2 motor channels, 4 sensor channels. PID controller for force, position and velocity. Servo update rate selectable
between 5 to 10 kHz
Force control
With the force control, PIMag? actuators and stages can be operated at a defined holding and feed force. Force
and position sensors are read and the sensor values are processed simultaneously. Thus it is possible to add a
secondary position or velicity control loop to the force control. PI offers PIMag? actuators with additional force
sensor. The models C-413.20A / .2GA provide analog input sockets for external force sensors
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. Auto zero function defines holding current level at which
the drive in open- loop operation outputs a force of 0 N , e.g. for compensating gravity. ID chip support: Identifies
the connected stages and simplifies configuration and exchange of stages. Supports direction- sensing reference
point switches. Extensive software support, e.g. for LabVIEW, dynamic libraries for Windows and Linux
Interfaces
USB 2.0, SPI for sending commands. Digital inputs and outputs for automation. Optional analog inputs and
outputs, e.g. for sensors, for sending commands or for position feedback
