General Description The LD is a 2 axes linear driver, optimally designed for low power DC Brush motors, in the range of up to 20W. Highlights Compared with PWM drivers, the linear driver has two advantages: The linear driver does not transmit electrical noise and is ideal for noise sensitive applications.
The linear driver does not generate high frequency ripple current which is a critical issue since the inductance of the low power motors is generally very low.
The driver gain, typically 0.3 A/V for full range of 3A, is user adjustable, independently for each motor, down to 0.04 A/V, for a full range of 0.4A. This provides wide dynamic range and high resolution for all types of motors and applications.
The LD includes internal protections for over current (peak and continuous), over voltage and over temperature. The LD has a perfectly linear response around zero command and presents no dead-band. Technology Using high density Surface Mount Technology, the LD performance and reliability are unique for its size and cost.

Motion Control Cards with Special PIEZO (Ceramic) Motor Functions Motion Control Chips with special functions to compensate PIEZO Motor behaviour Products Names: - POSYS® 1800-PIEZO Series
- POSYS® 1900-PIEZO Series
Description: The POSYS® 1800-PIEZO, POSYS® and 1900-PIEZO are motion control cards (PC-104, PCI-bus and Standalone) for servo and stepper motors and provide one to four axes of motion. The functionality of these series has been significantly improved by using a special motion control chip with enhanced PIEZO (Ceramic) control functions. It is now possible to compensate the special behaviour of PIEZO (Ceramic) motors like for example stiction. |
