Communication Option Card to Master Drive (Drive
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 [Communication Error Selection].
• Slave drive
Detects CE [Modbus Communication Error] and operates as specified by H5-04 [Communication Error Stop Method].
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 [Comm 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 [CE Detection Time] is expired. Then it operates in as specified with H5-04 [Communication Error
Stop Method].
• 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.
Master Drive (Drive 0) to Slave Drives (Drives 1 to
0)
• Uses MEMOBUS communications .
• Drive 0 sends data from its special registers to Drives 1
to 4.
