New Compact, Programmable Motor Controller

Designed specifically for the open loop control of stepper motors sized Nema 17 to Nema 34, Nanotec Electronic has developed a controller that is fast and easy to parameterize and program via USB, according to the company. "The C5 controller is ideal for simple applications that do not require an encoder but demand dynamic performance and smooth running, such as CNC dental milling machines," said a company spokesperson.

The controller can be operated via clock-direction mode or through specification of the speed or position via the analog input. In addition, it supports application programs that are directly executed in the motor controller. Programs created in the C++ based programming language NanoJ are executed in the motor controller as machine code. They are synchronized with the digital inputs and outputs via the real-time operating system in 1-ms cycles and with the instructions received via the field bus. "Thus, the drive can be operated autonomously without a field bus connection to the PLC, such as for format adjustments or simple additional functions on machines," said the spokesperson.

A motor resonance suppression feature via software-based current control ("dspDrive") enables the C5 to be suitable for applications that require smooth-running, low-resonance stepper motors, such as those found in medical equipment, laboratory automation and optical devices.

"For more demanding closed loop applications, Nanotec offers the C5-E version," said the spokesperson. "It is equipped with a CANopen field bus interface and an encoder input, and it is designed for stepper motors and BLDC motors with a continuous output of up to 250 watts."
