Risk Assessment
Under fault conditions, power loss or unintended operating conditions, the drive may not operate as
intended. In particular:
•Stored energy might not discharge to safe levels as quickly as suggested and can still be present
even though the drive appears to be switched off.
•The motor's direction of rotation might not be controlled
•The motor speed might not be controlled
•The motor might be energised
A drive is a component within a drive system that may influence its operation or effects under a fault
condition. Consideration must be given to:
•Stored energy
•Supply disconnects
•Sequencing logic
•Unintended operation
1.5 Safety Information
Risk of Electric Shock
DANGER!
Ignoring the following may result in injury:
- This equipment can endanger life by exposure to rotating
machinery and high voltages.
- The equipment must be permanently earthed due to the high
earth leakage current, and the inverter motor must be connected
to an appropriate safety earth.
- Ensure all incoming supplies are isolated before working on the
equipment. Be aware that there may be more than one supply
connection to the inverter.
- There may still be dangerous voltages present at power terminals
(motor output, supply input phases, DC bus and the brake, where
fitted) when the motor is at standstill or is stopped.
- For measurements use only a meter to IEC 61010 (CAT III or
higher). Always begin using the highest range.
CAT I and CAT II meters must not be used on this product.
- Allow at least 5 minutes for the inverter's capacitors to discharge
to safe voltage levels (<50V). Use the specified meter capable of
measuring up to 1000V dc & ac rms to confirm that less than 50V
is present between all power terminals and between power
terminals and earth.
- Unless otherwise stated, this product must NOT be dismantled. In
the event of a fault the inverter must be returned. Refer to
"Routine Maintenance and Repair".

Safety & EMC Requirements
Where there is a conflict between safety and EMC requirements, personnel safety shall always take
precedence.
WARNING!
Ignoring the following may result in injury or
damage to equipment:
- Never perform high voltage resistance checks on the wiring
without first disconnecting the inverter from the circuit being
tested.
- Whilst ensuring ventilation is sufficient, provide guarding and /or
additional safety systems to prevent injury or damage to
equipment.
- When replacing an inverter in an application and before returning
to use, it is essential that all user defined parameters for the
product’s operation are correctly installed.
- When replacing an inverter in an application and before returning
to use, it is essential that all user defined parameters for the
product’s operation are correctly installed.
- All control and signal terminals are SELV, i.e. protected by double
insulation. Ensure all external wiring is rated for the highest
system voltage.
- Thermal sensors contained within the motor must have at least
basic insulation.
- All exposed metalwork in the Inverter is protected by basic
insulation and bonded to a safety earth.

6 Installation
DANGER!
RISK OF ELECTRIC SHOCK
Terminal covers, main covers, and cover fixings must remain in place
while the drive is energized.
These should only be removed once the supply to the unit and/or system
has been disconnected, and the residual energy in the DC link capacitors
has been discharged.
CAUTION!
ESD SENSITIVE EQUIPMENT
Take ESD precautions when handling the Communication Interface
Option Cards to avoid any risk of damaging the equipment.
•All activities covered in this chapter should be carried out when there is no power to the inverter.
•If the drive has been powered up, ensure enough time has elapsed that the inverter has discharged
its residual energy.
•Always check that the voltages on the user terminals are at a safe level (<50V) before carrying out
any of these activities.

8 Configuration
The option comms configuration is accessible through the keypad under the menu Option Comms,
through DSE Lite function block Option Comms Config or through the webserver following the path Home
> Engineer > Communications > Option Comms.
The AC20 Ethernet IP option requires configuration of both communication parameters and process data
mapping.
8.1 Communication parameters
Keypad Menu Path
DSE-Lite Function Block
Webserver
The network parameters of the slave must be set to establish communication with master.
•The parameter 0691 COMMS REQUIRED must be set to Ethernet IP.
•The parameter 0758 ADDRESS ASSIGNMENT slects the slave IP Addressing method.
•There are three methods to set the IP address, subnet mask and gateway address of the device: the
slave sets its own address, the address is set externally by an Ethernet IP master, or the address is
set by a DHCP server.
•If the IP address is set by the slave (Address Assignment = FIXED) then three further parameters
must be set:
0759 SET IP ADDRESS
0760 SET SUBNET MASK
0761 SET GATEWAY ADDRESS
•The parameter 0762 ACCESS may be set to enable web features of the AC20 option comms (IP
Config Enable, Web Enable, Web Parameters Enable, FTP Enable, FTP Admin Mode).

8.2 Process Data
AC20 parameters implementation
The AC20 Ethernet/IP option requires configuration of process data mapping.
Config Mapping
The AC20 Ethernet IP option requires configuration of process data mapping. Parameters mapped as
Process Data can be exchanged cyclically as Process Data Objects (PDOs) on the bus.
Set process data using AC20 input and output mapping tables
These tables are two parameter arrays in which AC20 parameter numbers may be added.
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.

Write Mapping:
The write process data represents cyclic data sent from the AC20 to the PLC, this is mapped into the table
Option Comms Output Mapping.
Keypad Menu Path
DSE Lite Function Block
Webserver
Note: String-type parameters cannot be mapped.
Default Mapping: The process data mapping will contain a factory default mapping. The default mapping
may be overwritten if required.
Assembly mapping object instance
The process data is represented as dedicated instances in the assembly object (CIP), the Assembly object
uses static assemblies and holds the Process Data sent/received by the master. It allows data to and from
each object to be sent or received over a single connection.
Process data “Input” will produce data on the network and process data output will consume data from the
network.

Cyclic Data Exchange
Cyclic data exchange will occur when a Class 1 connection is established (active or idle). However, the
read process data will only update the mapped parameters when in the PROCESS ACTIVE state.
On a 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 the webserver and
are valid if Parameter 0774 Comms State = PROCESS ACTIVE.
8.3 Acyclic Data Exchange
Acyclic access of the AC20 parameters may be achieved using explicit messaging via EtherNet/IP Get and
Set attribute requests to the CIP object A2h. The instance number of this object corresponds directly to the
AC20 parameter number. The supported services are Get Attribute Single and Set Attribute Single.
