Product Overview
2.1
Introduction
The
iPOS4808
is a family of fully digital intelligent servo drives, based on the latest DSP technology and they offer
unprecedented drive performance combined with an embedded motion controller.
Suitable for control of brushless DC, brushless AC (vector control), DC brushed motors and step motors, the iPOS4808
drives accept as position feedback incremental encoders (quadrature or sine/cosine), absolute encoders (SSI and
BiSS-C) and linear Hall signals
.
All drives perform position, speed or torque control and work in single, multi-axis or stand-alone configurations. Thanks
to the embedded motion controller, the iPOS4808 drives combine controller, drive and PLC functionality in a single
compact unit and are capable to execute complex motions without requiring intervention of an external motion controller.
Using the high-level Technosoft Motion Language (
TML
) the following operations can be executed directly at drive level:
Setting various motion modes (profiles, PVT, PT, electronic gearing or camming, etc.)
Changing the motion modes and/or the motion parameters
Executing homing sequences
Controlling the program flow through:
Conditional jumps and calls of TML functions
TML interrupts generated on pre-defined or programmable conditions (protections triggered,
transitions on limit switch or capture inputs, etc.)
Waits for programmed events to occur
Handling of digital I/O and analogue input signals
Executing arithmetic and logic operations
By implementing motion sequences directly at drive level you can really distribute the intelligence between the master
and the drives in complex multi-axis applications, reducing both the development time and the overall communication
requirements. For example, instead of trying to command each movement of an axis, you can program the drives using
TML to execute complex motion tasks and inform the master when these tasks are done. Thus, for each axis control
the master job may be reduced at: calling TML functions stored in the drive EEPROM and waiting for a message, which
confirms the TML functions execution completion.
For iPOS4808 commissioning
EasySetUp
or
EasyMotion Studio
PC applications may be used.
EasySetUp
is a subset of EasyMotion Studio, including only the drive setup part. The output of EasySetUp is a set of
setup data that can be downloaded into the drive EEPROM or saved on a PC file. At power-on, the drive is initialized
with the setup data read from its EEPROM. With EasySetUp it is also possible to retrieve the complete setup information
from a drive previously programmed. EasySetUp shall be used for drive setup in all cases where the motion commands
are sent exclusively from a master. Hence neither the iPOS4808 TML programming capability nor the drive camming
mode are used.
EasySetUp can be downloaded free of charge from Technosoft web page.
EasyMotion Studio
platform includes EasySetUp for the drive setup, and a
Motion Wizard
for the motion
programming. The Motion Wizard provides a simple, graphical way of creating motion programs and automatically
generates all the TML instructions.
With EasyMotion Studio you can execute complex motions, thanks to their built-in
motion controller
s. EasyMotion Studio, may be used to program motion sequences in TML. This is the iPOS4808 typical
CAN operation mode when TMLCAN protocol is selected. EasyMotion Studio can also be used with the CANopen
protocol, if the user wants to call TML functions stored in the drive EEPROM or to use the camming mode. With camming
mode, EasyMotion Studio offers the possibility to quickly download and test a cam profile and also to create a
.sw
file
with the cam data. The .sw file can be afterwards stored in a master and downloaded to the drive, wherever needed.
A
demo version of EasyMotion Studio (with EasySetUp part fully functional) can be downloaded free of charge
from Technosoft web page.
