PC-based motion control goes
multitasking
Motor Technology has launched what it claims to be its newest and most feature packed motion control cards for ISA, PCI and CPCI PC bus operation.
Motor Technology has launched what it claims to be its newest and most feature packed motion control cards for ISA, PCI and CPCI PC bus operation Manufactured by Acroloop, the cards' multitasking kernels can perform motion, nonmotion (ie calculations for next action), PLC programs, and multithreaded, simultaneous communications on all communication ports and scan I/O concurrently

Space saving opportunities from servo worm gearbox
A new range of servo worm gearboxes with three alternative precision levels has been launched by Motor Technology with ten, five and one arc minutes of backlash options
Suitable for up to 16 axes, the new cards offer advanced high-speed motion control by using 32bit, floating-point DSPs, and by implementing a pre-emptive multitasker, a servo update rate of 250us for four axes is achieved.
The new cards have the ability to perform floating-point maths every DSP cycle, as opposed to the usual control-loop cycle time which is considerably slower.
As the cards are not limited to a 5ms calculation time there is no speed loss when performing high accuracy operations.
This is particularly important in general automation applications implementing registration, gearing and CAM control, as well as machine tool applications where accurate path control is crucial.
