Controller to Communication Option
• The controller and card communicate in the format of
each field bus communications protocol.
• Drive 0 sends commands and monitors through normal
field bus communications.
• The special registers of Drive 0 use read and write to
send commands to and monitor Drives 1 to 4.

Table 12.34 Operation in Gateway Mode
Communication Option to Master Drive (Drive 0)
Field bus communication data is written to and read from
the special registers of Drive 0.
• Master drive
Detects bUS [Option Communication Error] and operates as specified by F6-01 [Comm.Error Selection].
• Slave drive
Detects CE [Modbus Communication Error] and operates as specified by H5-04 [Mbus Error Stop].
Note:
• After error detection, each drive can continue the operation specified by the last received command if the F6-01 and H5-04 settings
agree. Because the controller cannot stop the operation, you must supply a stopping method, for example an emergency stop
switch.
• If you set H5-05 = 0 [Mbus Fault Detection Selection = Disabled], the drive will not detect CE. The H5-04 setting does not have
an effect.
• Master drive
Detects oFAxx and coasts to stop.
• Slave drive
Detects hLCE [High Level Communication Errors] and coasts to stop.
The master drive stops communicating with the slave drive in these conditions: Reset the fault to restart communication.
The slave drive detects CE after H5-09 [Mbus CE Detect Time] is expired. Then it operates in as specified with H5-04 [Mbus Error
Stop].
• A message error occurred in the send data from the slave drive 10 consecutive times.
• Response from the slave drive timed out 10 consecutive times.

• Uses Modbus communications.
• Drive 0 sends data from its special registers to Drives
1 to 4.
Operation
Description
This flag enables command updates.
To input the Run command and frequency reference at the same time, write all
commands, then change the bit value from 0 to 1.
The unit of measure changes when o1-03 changes.
