2 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, BiSS-C
and EnDAT2.2
1
) and linear Hall signals
2
.
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 gearing1or camming
3
, 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
4
❑Sending commands to a group of axes (multicast). This includes the possibility to start
simultaneously motion sequences on all the axes from the group2
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.
All iPOS4808 BX drives are equipped with a serial RS232 and a CAN 2.0B interface that can be set by
hardware pins to operate in 2 communication protocol modes:
❑CANopen
❑TMLCAN
When CANopen mode is selected, the iPOS4808 conforms to CiA 301 v4.2 application layer
communication profile, the CiA WD 305 v2.2.13 and CiA DSP 402 v3.0 device profile for drives and motion
control, now included in IEC 61800-7-1 Annex A, IEC 61800-7-201 and IEC 61800-7-301 standards. In this
mode, the iPOS4808 may be controlled via a CANopen master. The iPOS drive offers the possibility for a
CANopen master to call motion sequences/ functions, written in TML and stored in the drive EEPROM,
using manufacturer specific objects. Also, the drives can communicate separately between each other by
using non reserved 11 bit identifiers.
When TMLCAN mode is selected, the iPOS4808 behaves as standard Technosoft intelligent drive and
conforms to Technosoft protocol for exchanging TML commands via CAN-bus. When TMLCAN protocol is
used, it is not mandatory to have a master. Any iPOS4808 can be set to operate standalone, and may play

the role of a master to coordinate both the network communication/synchronization and the motion
application via TML commands sent directly to the other drives.
When higher level coordination is needed, apart from a CANopen master, the iPOS4808 drives can also be
controlled via a PC or a PLC using one of the TML_LIB motion libraries.
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 controllers. 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.

2.4.2 Dual loop configurations
The motor speed control loop is closed on one feedback connected on the motor while the motor position
control loop is closed on the other available feedback which is placed on the load. There is usually a transmission
between the load and the motor.

feedback#2) on load; -DC brush motor with SSI encoder (from feedback #2) on motor and Sin/Cos encoder (from

3.2 Mechanical Mounting
The iPOS4808 drive is intended to be mounted vertically or horizontally on a on a metallic support using the provided
mounting holes and the recommended mating connectors, as specified in chapter “Mating connectors”.
For thermal calculations, each iPOS4808 BX drive can be assumed to generate 1 Watt at idle, and up to 5 Watts (= 17
BTU/hour) worst case while driving a motor and using all digital outputs.
When the iPOS4808 BX is mounted vertically, its overall envelope (size) including the recommended mating connectors
is shown in Figure 3.1. Fixing the iPOS4808 BX onto a support using the provided mounting holes is strongly
recommended to avoid vibration and shock problems.
Figure 3.2.1. iPOS4808 BXO dimensions with mating connectors
The iPOS4808 BX-CAN drive(s) can be cooled by natural convection. The support shall be thermally conductive
(metallic), and can be mounted vertically or horizontally.
Figure 3.2.2. Recommended spacing go vertical and horizontal mounting, worst case: non-metallic, closed box
The figures above shows the minimum spacing to assure proper airflow by natural convection.
If closed completely in a box, ventilation openings shall be foreseen on the top and bottom sides.

©Technosoft 2023 15 iPOS4808 BX-CAN / -STO Technical Reference
If ventilation driven by natural convection is not enough to maintain the temperature surrounding the iPOS4808 BX
drive(s), then alternate forced cooling methods must be applied.
Remark: In case of using a metallic box, with ventilation openings, all spacing values may be reduced
substantially. With proper ventilation, keeping the air surrounding the iPOS4808 BX inside the limits
indicated, the spacing values may be reduced down to zero.

3.4.3 24V Digital I/O Connection
3.4.3.1 PNP inputs
Figure 3.5. 24V Digital PNP Inputs connection
Remarks:
1. The inputs are selectable as PNP/ NPN by software.
2. The inputs are compatible with PNP type outputs (input must receive a positive voltage value (5-36V) to change
its default state)
3. The length of the cables must be up to 30m, reducing the exposure to voltage surge in industrial environment.
3.4.3.2 NPN inputs
Figure 3.6. 24V Digital NPN Inputs connection
Remarks:
1. The inputs are selectable as PNP/ NPN by software.
2. The inputs are compatible with NPN type outputs (input must be pulled to GND to change its default state)
3. The length of the cables must be up to 30m, reducing the exposure to voltage surges in industrial environment.
