Multi-Axis Piezo Control Unit
Multi-Axis Piezo Control Unit is configured for independent control of
Four Piezo Actuators. The control is a completed system which includes
control unit, motor-drives and local high-voltage power supply.
Piezo Control provides up to 300mA output drives current and provides
also higher RF immunity for the axes with strain gauge feedback sensors. The
Computing and Control resources of the Control Unit are provided by a
400MHz SHARC DSP based MCM-4 Control Module. The communication
between the Controller and machine computer uses an Ethernet connection
(10/100Mbps).
The Control Unit features advanced high precision motion control of Piezo
Actuators and supported by Mega-Fabs WizAlg – a powerful development,
programming, analyzing and debugging tools.
