4 Inverter Control
4 - 2 EtherCAT Communication Unit USER’S MANUAL (3G3AX-MX2-ECT)
4-1 Outline
This section describes how to use the EtherCAT Communication Unit to control the inverter.
Inverter control is performed by allocating a function object to a PDO.
These functions are limited depending on the combination with the used Master Unit.
* 1 When using a Master Unit from another manufacturer, check yourself whether it supports the above functions.
* 2 If you are using your NJ501-1x00 as the master, refer to the explanation on allocation in PDO free format.
Allocate the object that you want to use to a PDO with the procedure below.
1
Allocate the object to a PDO.
2
Assign the PDO to Sync Manager.
Use the tool of the Master Unit for allocation.
This unit uses the PDOs below to allocate the objects.

RxPDO (master to slave)

TxPDO (slave to master)
4-1-1 Function Selection
Type Details
Allocation when using CJ1W-NCx82 The fixed allocation when connected with OMRON's CJ1W-NCx82.
Independent profile OMRON's independently-developed function object.
Enables easy control of the inverter.
CiA402 drive profile A function object that conforms to the CiA402 drive profile.
PDO free format Objects can be freely allocated, including the above objects.
4-1-2 Object Mapping
PDO Mapping
PDO Details
1600 hex to 1604 hex
(1st receive PDO Mapping to
5th receive PDO Mapping) Objects can be freely allocated. Up to 2 objects (maximum size of 4 bytes) can be
allocated to each PDO.
1700 hex
(257th receive PDO Mapping) The fixed allocation that conforms to the CiA402 drive profile.
1701 hex
(258th receive PDO Mapping) The fixed allocation of the independent profile.
PDO Details
1A00 to 1A04 hex
(1st transmit PDO Mapping to
5th transmit PDO Mapping) Objects can be freely allocated. Up to 2 objects (maximum size of 4 bytes) can be
allocated to each PDO.
1B00 hex
(257th transmit PDO Mapping) The fixed allocation that conforms to the CiA402 drive profile.
1B01 hex
(258th transmit PDO Mapping) The fixed allocation of the independent profile.
1BFF hex
(512th transmit PDO Mapping) By default, Sysmac Studio assigns 2002 hex: Sysmac error status.
