Introduction
1.Functions
- Three closed-loop control modes Integrated current loop, speed loop and position loop control. Supports profile position, profile velocity, torque mode, home search and point-to-point positioning. Compatible with brushed DC motors (with encoder) and brushless EC motors (with Hall sensors + encoder). For EC motors, it adopts space vector sinusoidal commutation to reduce torque ripple and running noise.www.plcva.com
- Multi communication interfaces Main bus: CANopen (CiA 301 / CiA 402 servo profile), works as CAN slave node. Additional USB and RS232 for PC debugging via EPOS Studio software; supports USB-to-CAN gateway function.
- Encoder & I/O processing Receives differential incremental encoder signals up to 5 MHz. Equipped with digital inputs/outputs and 2 channels of 12-bit analog input for limit switch, home sensor, trigger and analog setpoint.
- Built-in protection & diagnostic Overcurrent, overvoltage, undervoltage, overtemperature, motor short-circuit and position tracking error protection. It records fault codes and uploads diagnostic status to host controller for troubleshooting.
- High efficiency power stage 100 kHz PWM power drive, maximum efficiency up to 90%. Small lightweight design (27g), M2.5 flange mounting for embedded integration.
- Programmability Parameters and motion sequences can be configured in EPOS Studio. Supports secondary development via DLL / shared library for C#, C++, LabVIEW, IEC61131-3 PLC systems.

2. Applications
It is a miniature high-precision digital servo drive for maxon small DC/EC motors, widely used in automated equipment requiring compact precise motion control.
Typical Equipment: Semiconductor test equipment, optical inspection instruments, medical devices, lab automation, robotics joints, precision positioning stages, packaging machinery, 3D inspection scanners.
Core Purpose: Drive small maxon brushed DC or brushless EC motors to realize high-accuracy speed regulation and point-to-point positioning. It executes closed-loop motion control locally and exchanges motion commands with upper PLC/IPC through CANopen bus. Ideal for compact machinery with limited installation space. It is commonly used in new machine development and spare replacement for existing automated production lines.www.plcva.com
