CA306

Data preset unit with CANopen interface

Product Features:

 CA306 is a simple data preset unit with a BCD-coded thumbwheel switch. The unit

allows an easy remote setting of single parameters (e. g. speed setting of a drive) via
fieldbus. By pressing the ENTER button, the actual BCD setting will be transmitted to
the selected register of the target unit as SDO (Service Data Object).

* For data transmission as PDO (Process Data Object) according to CiA DS 301, our

* alternative version CA307 can be used.

1. Safety Instructions and Responsibility

1.1. General Safety Instructions

This operation manual is a significant component of the unit and includes important rules and
hints about the installation, function and usage. Non-observance can result in damage and/or
impairment of the functions to the unit or the machine or even in injury to persons using the
equipment!

Please read the following instructions carefully before operating the device and observe all
safety and warning instructions! Keep the manual for later use.

A pertinent qualification of the respective staff is a fundamental requirement in order to use
these manual. The unit must be installed, connected and put into operation by a qualified
electrician.

Liability exclusion: The manufacturer is not liable for personal injury and/or damage to property
and for consequential damage, due to incorrect handling, installation and operation. Further
claims, due to errors in the operation manual as well as misinterpretations are excluded from
liability.

In addition the manufacturer reserve the right to modify the hardware, software or operation
manual at any time and without prior notice. Therefore, there might be minor differences
between the unit and the descriptions in operation manual.

The raiser respectively positioner is exclusively responsible for the safety of the system and
equipment where the unit will be integrated.

During installation or maintenance all general and also all country- and application-specific
safety rules and standards must be observed.

If the device is used in processes, where a failure or faulty operation could damage the system
or injure persons, appropriate precautions to avoid such consequences must be taken.

1.2. Use according to the intended purpose

The unit is intended exclusively for use in industrial machines, constructions and systems. Non­conforming usage does not correspond to the provisions and lies within the sole responsibility
of the user. The manufacturer is not liable for damages which has arisen through unsuitable
and improper use.

Please note that device may only be installed in proper form and used in a technically perfect
condition (in accordance to the Technical Specifications, see chapter 10).

The device is not suitable for operation in explosion-proof areas or areas which are excluded by
the EN 61010-1 standard.

Ca306_01d_oi_e.doc / Apr-16 Page 4 / 10

1.3. Installation

The device is only allowed to be installed and operated within the permissible temperature
range. Please ensure an adequate ventilation and avoid all direct contact between the device
and hot or aggressive gases and liquids.

Before installation or maintenance, the unit must be disconnected from all voltage-sources.
Further it must be ensured that no danger can arise by touching the disconnected voltage­sources.

Devices which are supplied by AC-voltages, must be connected exclusively by switches,
respectively circuit-breakers with the low voltage network. The switch or circuit-breaker must
be placed as near as possible to the device and further indicated as separator.

Incoming as well as outgoing wires and wires for extra low voltages (ELV) must be separated
from dangerous electrical cables (SELV circuits) by using a double resp. increased isolation.

All selected wires and isolations must be conform to the provided voltage- and temperature­ranges. Further all country- and application-specific standards, which are relevant for structure,
form and quality of the wires, must be ensured. Indications about the permissible wire cross­sections for wiring are described in the Technical Specifications (see chapter 10).

Before first start-up it must be ensured that all connections and wires are firmly seated and
secured in the screw terminals. All (inclusively unused) terminals must be fastened by turning
the relevant screws clockwise up to the stop.

Overvoltages at the connections must be limited to values in accordance to the overvoltage
category II.

For placement, wiring, environmental conditions as well as shielding and earthing/grounding of
the supply lines the general standards of industrial automation industry and the specific
shielding instructions of the manufacturer are valid.

Please find all respective hints and rules on www.motrona.com/download.html

--> “[General EMC Rules for Wiring, Screening and Earthing]”.

1.4. Cleaning, Maintenance and Service Notes

To clean the front of the unit please use only a slightly damp (not wet!), soft cloth. For the rear
no cleaning is necessary. For an unscheduled, individual cleaning of the rear the maintenance
staff or assembler is self-responsible.

During normal operation no maintenance is necessary. In case of unexpected problems, failures
or malfunctions the device must be shipped for back to the manufacturer for checking,
adjustment and reparation (if necessary). Unauthorized opening and repairing can have
negative effects or failures to the protection-measures of the unit.

2. Introduction

The CA306 unit has been designed for remote control of single parameters (like position or
speed) in systems using a CANopen network for communication.

 CA306 is standardly supplied with 6 digits (preset range: 0 … 999 999) and built into a

DIN housing.

 With supplementary ordering information “Option VZ000“, the unit is supplied as

version with 5 digits + sign (preset range: -99 999 … +99 999).

 Both versions are suitable for communication on the CANopen parameter channel,

accessing adjustable register codes of a network participant.

For operation on the process data level, the special PDO version CA307 is available.

The version with a sign (option VZ000) requires slider 4 to be “ON“ at any time!

6. Setting of unit address, register code and store function

Sliders 1-5 of the 8-position DIL switch will select the unit address of the target device (00-31).

Slider 6 selects only temporary use of transmit data (with no storage to the EEProm), or stores
data to the EEProm for further use even after power down (by transmitting Store EEPROM to
Code C003).

Slider 7 and 8 determine the register codes to be accessed in the target unit. Codes shown in
subsequent list refer to LENZE series 9300 drives. Other code classifications are possible at any
time.

Important note: All DIL switch settings are only read upon initialization and
changes during normal operation will not be recognized! After change of DIL
switch settings, the unit must be powered up again!

7. The front LED

This multi-purpose LED informs about the actual state of data communication, using different
blinking sequences. With normal communication, this LED lights all the time. Where
communication problems appear, the meaning of different blinking sequences is explained by

Errors 2...7 can be reset by pressing the Enter button.
To reset Error 1 it is necessary to switch off the unit and power up again.

8. Transmission details

The unit transmits the data by SDO (Service Data Object) Write Request and awaits a
corresponding Write Response within the next 2.5sec (Timeout). It operates similar to a
CANopen master (But it is no CANopen master!). No other CANopen communication objects
are supported, except the SDOs.
