Figure 12.64 Connection Examples in Gateway Mode
Table 12.48 Specification
Item Specification
Applicable options All options that support the MEMOBUS access function (for example, PROFIBUS-DP, PROFINET, EtherNet/IP, EtherCAT)
Compatible Products Drives that can set F6-16 [Gateway Mode]
*1
Number of connected drives Maximum: 5 units
Communication specifications MEMOBUS/Modbus (RTUmode) communications
Commands/responses The controller can send this data to each drive (Drive 0 to Drive 4):
• Control commands: Run commands and frequency references
• Control responses: Output frequency and drive status (during run, faults)
• Read and write parameters
• Read monitors
Synchronous control Not supported
*1 Gateway Mode is not available with Yaskawa 1000-series drives or previous series drives.
Note:
• The communication speed in gateway mode is slower than the speed in fieldbus communications. Make sure that the speed is
acceptable for your system.
• Response speed with the communication option is slower than with point-to-point communications.
• Set H5-03 [Communication Parity Selection] to the same value on the master drive and slave drives.
WARNING! Injury to Personnel. Separately prepare safety protection equipment and systems, for example fast stop switches. If
the motor does not stop correctly from the disconnection of communications cable or electrical interference, it can cause serious
injury.

*1 Re-energize 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.
