Note: It is possible to make serial communications operate without adhering to the following
recommendations; however, the recommendations will promote greater reliability.
Cable
The cable for CANopen is shielded copper cable consisting of one twisted pair and two optional cables for
an extra power supply. The CANopen option does not use the external power supply. The use of
CAN_GND is recommended throughout the network. The user organization (CiA) has specified ISO/DIS
11898 as the standard bus cable.
The maximum allowable cable length depends on the baud rate selected:
Data Rate
Maximum Distance
125 kBit/s
500 metres
250 kBit/s
250 metres
500 kBit/s
100 metres
1 MBit/s
25 metres
Terminators
•If the drive is at the end of the chain, it must have a terminating resistor.
•All other drives in the system should not have a terminator.
•Required resistor is + 1%, minimum ¼ Watt)
•The CANopen specification recommends 124Ω, but it should be chosen to equal as closely as
possible the characteristic impedance of the cable.
Important: Failing to fit terminating resistors correctly may result in unreliable operation.

8.2 Process Data
AC20 parameters implementation
The AC20 CANopen data can be accessed from the network via dedicated object entries in the object
dictionary. The object dictionary contains Standard, Manufacturer and Profile Specific Objects.
The CANopen manufacturer specific range (index 2001h to FFFFh) of object entries corresponds directly to
the AC20 parameters numbers.
Each object entry corresponds to an AC20 parameter number, with parameter number 1 corresponding to
object index 2001h, parameter number 2 to object index 2002h, etc.
For standard parameters (of a single element), sub-index 00h of the object represents the value of the
parameter, its data type and access depend on the AC20 parameter.
For multiple element parameters (parameter arrays), sub-index 00h represents the number of parameter
elements and sub-indexes 01h-FEh represents the value of each of the parameter elements.
In the example below parameter number 1 is a single element parameter and parameter number 2 is a 4-
element parameter array:

Config Mapping
The AC20 CANopen option requires configuration of process data mapping. Parameters mapped as
Process Data can be exchanged cyclically as Process Data Objects (PDOs) on the bus.
The slave supports up to 4 TPDOs and up to 4 RPDOs, each capable of carrying up to 8 bytes of data.
(See Appendix – CANopen Object Dictionary)
There are two methods to define process data mapping: The process data can be mapped using the AC20
input and output mapping tables or from the PLC.
The parameter 2566 MASTERMAPPING defines the method: If FALSE the AC20 input and output mapping
tables will be used to configure process data mapping. If TRUE, the bus master set/configures the Process
data mapping and AC20 input and output mapping tables will be cleared.
Note: For parameter 2566 MASTERMAPPING = ‘FALSE’:If the AC20 mapping tables are both set to
zeros or AC20 mapping tables differs from PLC mapping then the option will be mapped from the PLC.

Set process data using AC20 input and output mapping tables
These tables are two parameter arrays in which AC20 parameter numbers may be added. The parameter
2566 MASTERMAPPING must be set to FALSE.
Read Mapping:
The read process data represents cyclic data sent from the PLC to the AC20, this is mapped into the table
Option Comms Input Mapping. Only writable AC20 parameters that are not configuration parameters may
be added to the read process data.

Set process data from CANopen master
The eds file defines the list of manufacturer specific objects. Each object corresponds to an AC20
parameter.
When configuring the PLC, the objects may be mapped to the process data objects (PDO) as required.
These objects map to the process data in the order in which they are added.
The parameter 2566 MASTERMAPPING must be set to TRUE and this will auto reset any AC20 input and
output mapping inside the drive.
Cyclic Data Exchange
Cyclic data exchange will occur when the option is in the OPERATIONAL (PROCESS ACTIVE) or STOP
(IDLE) state.
However, the read process data will only update the mapped parameters when in the PROCESS ACTIVE
state.
On transition into the PROCESS ACTIVE state all read process mapped parameters will be updated.
When in the PROCESS ACTIVE state, the read process mapped parameters will all update only when a
change in the read process data occurs.
Mapping status
The process data mapping status can be accessed from AC20 via the following parameters:
•Parameter 2586 InMappingStatus: shows the status of the currently active cyclic data input
mapping table (32 entries), value is the Tag ID of the parameter to be cyclic read In.
•Parameters 2619 OutMappingStatus: Shows the status of the currently active cyclic data output
mapping table (32 entries), value is the Tag ID of the parameter to be cyclic sent out.
The parameters 2586 InMappingStatus and 2619 OutMappingStatus are visible from webserver if
Parameter 2566 MasterMapping = TRUE and are valid if Parameter 0774 Comms State = PROCESS
ACTIVE.
