*1 Restart the drive to apply the new settings.
*2 Specify the number of slave drives you will connect.
*3 Setting 0 will not let the drive respond to MEMOBUS/Modbus communications.
*4 Set a slave address that is different from other slave devices.
*5 Enter the same value that you use for the master drive.
*6 To correctly detect the response timeout, do not change the value of H5-06 from the default value.
*7 Set H5-09 ≥ 0.9. When H5-09 < 0.9, the drive will detect CE [Modbus Communication Error] before it detects a response timeout.
*8 On each slave drive, set b1-01 [Frequency Reference Selection 1] and b1-02 [Run Command Selection 1] to 2 [Memobus/Modbus
Communications].
An Overview of Gateway Mode
When in gateway mode, the drive operates as shown in
A - Controller
B - Communication Option
Controller to Communication Option Card
• 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.
