Microstepping Driver PMD101

The PMD101 microstepping driver is a full featured 1-axis driver designed for use with Piezo LEGS® motors. It is able to determine a motors resolution down to the nanometre/microradian range and be used in demanding applications.
It is possible to drive in closed-loop mode when reading back position from a position sensor. The PMD101 driver supports quadrature and analogue encoders and serial synchronous interface (SSI) sensors. By issuing a single command, it can guide the motor to the exact encoder count and parameter settings for ramping behaviour.
This driver delivers up to 2048 micro-steps per waveform cycle. Waveforms optimised for speed, resolution or force are available. The unit communicates with the host through serial USB using ASCII commands.

Features and Benefits

• Nanometre resolution
• Closed loop regulation
• Open loop mode
• General I/O
• AC-DC adapter included

Functions

The driver controls the Piezo LEGS motor by feeding waveform signals which elongates and bends each of the piezo drive legs. The waveforms are specially designed to make the drive legs perform a precise walking motion. The motion of the drive legs is transferred via friction contact to a linear rod or to a rotary disc.
For each waveform cycle, the Piezo LEGS motor takes one full step. The waveform step length is load dependant but in the range of a few micrometres for a linear Piezo LEGS motor. Rotary Piezo LEGS motors have their drive legs working on the perimeter of a drive disc. The waveform step angle depends on the diameter of the rotary motor but is less than one milliradian.
The generated signal waveform is made up of many voltage target points in time. Each small voltage change moves the motor only by a fraction of a microstep. The PMD101 driver gives a maximum resolution of 2048 microsteps per full waveform step.

Driver

The PMD101 communicates with the PC via USB. Communication with the driver is through a protocol language (ASCII commands). Closed loop target mode and open loop mode are available, with full access to set resolution, step frequency (speed) and so on. Positional sensors are used to track the precise position of the Piezo LEGS motors. The driver can read limit switches and reset at index. Ramping parameters are set to prevent overshooting when closing in on target in closed loop operation.
