 COMM / RS485
The communication protocol can be chosen between Slink4, Modbus or Jbus through the
Protocol type parameter. Each of these protocols allow a multipoint network.
See the specific protocol manual for further details.
The Drive address can be defined via the M00.00 - Slave address parameter.
The address change is performed by editing parameter M00.00 - Slave address, and
saving the new value.
The new address becomes active after the Drive has been switched off and then back on.
A temporary address change is also possible when using the Slink4 protocol with an
Slink4 command.
When using the Slink4 protocol, the RS485 serial line operates in half-duplex, where the
data can not be transmitted and received simultaneously.
It is sometimes possible during the transition from transmission to reception modes, the
Master (PC or PLC) reaches the reception condition after the drive has already started to
send its data package. As a consequence, the package received by the master is not
correct. In order to avoid such occurrences, the M00.01 - Slave res time parameter can be
adjusted to delay the drive response so the Master has ample mode switching time.
This situation does not occur with the Modbus and Jbus protocols as the synchronization
pause between messages is specified by the protocol and is guaranteed.
Modbus regs mode parameters allows to set the floating point variables transmission:
MSW:LSW - reg=ipa MSW first, LSW after - register index = ipa
LSW:MSW - reg=ipa LSW first, MSW after - register index = ipa
MSW:LSW - reg=2ipa MSW first, LSW after - register index = ipa * 2
LSW:MSW - reg=2ipa LSW first, MSW after - register index = ipa * 2
(MSW=More significant word, LSW=Less significant word, register index = ipa).
