2. Product Overview
2.1. Introduction
The iPOS4808 BX-CAN is part of 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 BX-CAN drives accept as position feedback incremental encoders
(quadrature or sine/cosine) and linear Halls 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 BX-CAN 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

Performing data transfers between axes

Controlling motion of an axis from another one via motion commands sent between
axes

Sending commands to a group of axes (multicast). This includes the possibility to start
simultaneously motion sequences on all the axes from the group

Synchronizing all the axes from a network
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.
