STAND-ALONE MOTION CONTROLLER
Supplier: ACS Motion Control
ACS Motion Control, an international
manufacturer of advanced multi-axis motion controllers, machine controllers and
integrated control modules, has developed a cost-efficient, stand-alone motion controller
that provides multi-axis control for simple and demanding applications. Designated
SPiiPlus-LF, the small form factor, four axes motion controller features off-board
extensions to provide up to 64 axes of control using a CANopen network. The SPiiPlus-
LF is PLCopen compliant and, in addition to the ACSPL+ motion programming
language, it can also be programmed in any of the five IEC61131-3 standard PLC
languages. The SPiiPlus-LF provides fast, accurate motion using a high sampling rate of
20kHz on all axes.
“The SPiiPlus-LF enhances the performance of OEM machinery that requires
multi-axis synchronization at a lower cost by providing precise and smooth motion at a
high resolution without compromising accuracy and throughput. It is ideal for OEMs that
require a high-performance, low-cost board level solution,” said Evan Reed, Vice
President at ACS Motion Control. “In addition, as a member of the SPiiPlus family of
products, the LF is supported by ACS’ advanced SPiiPlus software tools.” The SPiiPlus-LF high-performance motion controller architecture uses the same
distributed multi-processor architecture as the rest of the SPiiPlus Family. It can be
board mounted or mounted on a DIN rail.
The controller can be used with various drive types, such as piezo ceramic, direct
drive rotary, linear motors, voice coils and low EMI linear amplifiers in applications
including semiconductor manufacturing, wafer inspection, electronic assembly, printing
The SPiiPlus-LF motion controller supports a wide range of modes, including
point-to-point, jog, segmented, master-slave and arbitrary path with PVT cubic
interpolation. The SPiiPlus-LF features third-order profile generation with on-the-fly
velocity, acceleration, jerk and target position changes. The position event generator
(PEG) and position registration (MARK) capabilities, both with sub-microsecond delay,
ensure accurate and precise control. In addition, optional on-board Sin-Cos encoder
interpolation is available.
ACS’ advanced SPiiPlus software is optimized for motion control applications
and provides easy setup, tuning, programming and application simulation. The software
enables the implementation of highly complex motion-time-event sequences with
accurate positioning and timing.
