I. System Overview
The ECC100 is a state-of-the-art motion controller, allo ing the
simultaneous operation of up to three positioners from attocube’s
industrial ECS Drive series. The positioners connected to the ECC100 can be
an arbitrary combination of encoded (/NUM) and open-loop positioners,
depending on the customer’s choice.
The ECC100 is designed to be operated remotely via a computer by using
the PC soft are interface “DAISY”. A basic version of DAISY is provided by
attocube systems by default, a fully-featured “PRO”-version of DAISY can
be purchased through attocube’s sales team. In addition to the PC soft are
interface, a *.DLL library is delivered ith each ECC100 unit, enabling
higher integration of the functionality of the motion controller into
customized soft are routines. For synchrotron applications, a /SYNC
option - consisting of physical Ethernet connectivity and EPICS driver set -
is available as an option.
With the ECC100, positioners of the ECS series can be driven in both open-
loop and closed-loop (only for /NUM encoded positioners) drive mode.
These t o modes are explained in the follo ing.
Open-loop positioning:
In this mode, all ECS positioners connected to the ECC100 motion
controller are operated ithout position feedback.
By setting appropriate piezo-drive voltages in the ECC100, the physical
step size of the positioner can be varied ithout any actual position
information. The speed of the motion of positioners is user-adjustable by
varying the step frequency bet een 1Hz and 5kHz. A frequency of 5kHz is
only available on one axis at any one time; frequencies up to 2kHz can be
handled on three axes simultaneously. Open-loop positioning is available
for all positioners of the ECS series.
Closed-loop positioning:
In this mode, encoded positioners connected to the ECC100 motion
controller are operated ith an active feedback loop on the position.
In contrast to the open-loop mode, the ECC100 allo s to set and control
the absolute position of targets (closed-loop positioning) ith a resolution
of 1nm for linear positioners and 1µ° for rotary positioners, respectively
(/NUM or /NUM+ encoder option). The closed-loop positioning is
especially valuable for those applications, here (i) no other physical
feedback on the target position is available, (ii) certain target positions
need to be frequently addressed, or (iii) accurate positioning is crucial.
Please refer to the specification sheets of the ECS positioners for further
information regarding motion specifications in closed-loop mode.
