Controller can be used.
Note: 1. When more than one G3ZA Multi-channel
Power Controller is connected, version 1 and
version 2 can be mixed. (Up to 8 G3ZA Multi-
channel Power Controllers can be
connected.)
2. Software version 2 of G3ZA Multi-channel
Power Controller can also be used with EJ1
version1.0.
• Autotuning is provided for heating/cooling control.
• Self-tuning has been added.
• A switch can be used to display the output status on
the operation indicators during operation.
• Modbus communications can be used to read and
write all parameters, and to execute any of the
operation commands.
• A switch setting can be changed to use Modbus
communications on port B.
• A switch setting can be used to set the baud rate of
port B.
• A C0/80 status has been added to the variable types.
• Up to eight G3PW Power Controllers can be
connected to one Basic Unit.
Note: 1. The G3PW can be connected to EJ1 V1.1.
2. The G3PW and G3ZA cannot be used
together.
Advanced Unit
(EJ1N-HFU@-NFL@)
• Programless communications can be used with 1: N
connections.
• The maximum number of parameters that can be
specified for programless upload/download settings
has been increased from 300 to 600 each.
• Connection is now possible to MELSEC-QnA/An/
AnS/FX3uc-series PLCs.
• A new setting read operation has been added to
programless communications: Setting Read 2.
• The speed of programless communications has
been increased.
• Either "continue" or "stop" can be selected for when
errors occur in programless communications.
• Bit specification operation commands have been
added to the parameters that can be specified for
programless download settings. This simplifies the
program when operation commands are executed.
• The G3ZA or G3PW Monitor parameter has been
added to the parameters that can be specified for
programless upload settings. Up to four G3ZA Multi-
channel Power Controllers or up to four G3PW
Power Controllers can be connected to one Basic
Unit.
• The maximum number of parameters that can be
specified for programless upload/download setting
has been increased from 600 to 1200 each.
• The maximum number of Basic Units that an HFU
with Programless Communications can control has
been increased from 16 to 32 Units.
• Communications unit numbers 32 to 39 can be used
in the HFU via programless communications.
This allows the communications unit numbers of
Basic Units connected to an HFU to be numbered
sequentially, making it easy to copy HFU and Basic
Unit settings to other HFUs and Basic Units.
