Table 2.41 Specification
Item
Specification
Applicable options
All the options that support the MEMOBUS access function (for example, PROFINET, EtherNet/IP, etc.)
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
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 the speed 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
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 [Serial Communications]
.
Gateway Mode Overview
In gateway mode, the drive operates as shown in
A - Controller
B - Communication Option
C - Master Drive (Drive 0)
D - Slave Drives (Drives 1 to 4)
