1.1 Overview
Features of the CANopen Modules
 Electrically isolated bus interface
 Data transfer rate from 10kbit/sec to 1 Mbit/sec
 Easy connection, optionally via M12 round plugs or screw terminals
 Integrated bus terminating resistor (switchable)
 CAN bus-specific status indication with 2 LEDs on the internal (Customer Unit) and external
(Technology Unit) technology option
 DEVICE or FI-specific status indication with 2 LEDs on the internal (Customer Unit) and external
(Technology Unit) technology option
 CAN interface as per specifications 2.0A and 2.0B
 Up to four 24V inputs and two 24V outputs are integrated into the bus module
 Direct connection of up to 4 sensors and 2 activators via M12 round plug connectors on the SK TU4-
CAO-M12(-C) version. Visualisation of signal status via LEDs
 Transmission and selection of process and parameter data
 CAN Bus gateway solution → up to 4 frequency inverters can be connected to a CANopen bus
module. Each FI is allocated its own SDO channel
 Up to 63 nodes (e.g. CANopen bus modules) on a single bus. With this, up to 252 frequency inverters
can be operated on a single bus by means of gateway.
 Support of 11 bit and 29 bit identifiers by the technology modules
 Supports DS-301 communications profile and DS-402 drive profile for “Velocity Mode” (with
Technology Units)
 Programming of all frequency inverter parameters using SDO
 Dynamic PDO mapping (5 TxPDOs and 5 RxPDOs) for great reduction in the number of parameters
 Heartbeat and node-guarding monitoring functionality
 Interface (RS232/RS485) for parameter access by means of the SK PAR-3H manual control unit or
NORDCON software via RJ12 connector (Except for SK CU4-CAO. Here parameter access via the
SK 200E frequency inverter is possible)
 Integrated EEPROM with extensive bus-specific parameter database with parameter editing facilities via:
- ParameterBox and Nordcon: direct access / direct saving
- CANopen Bus Saving via - Index 0x1010 sub0 Store Parameters,
- Index 0x1011 sub0 Restore default Parameters
 Available as versions for installation in the inverter (IP20) or in a separate housing (optionally IP55 / IP66)
1.2 Delivery
Check the equipment immediately after delivery/unpacking for transport damage such as deformation or
loose parts.
If there is any damage, contact the carrier immediately and implement a thorough assessment.
Important! This also applies even if the packaging is undamaged.
