Response interval (y09)
y09 or y19 specifies the latency time after the end of receiving a query sent from the host
equipment (such as a PC or PLC) until the start of sending the response. This enables the
inverter to control the response timing to match the host equipment that is slow in processing.
- Data setting range: 0.00 to 1.00 (s)
T1 = Response interval + α
where α is the processing time inside the inverter. α may vary depending on the
processing status and the command processed in the inverter.
For details, refer to the RS-485 Communication User's Manual (MEH448).
When configuring the inverter with FRENIC Loader via the RS-485
communications link, pay sufficient attention to the performance and configuration
of the PC and protocol converter such as USB−RS-485 converter. Some protocol
converters monitor the communications status and switch between sending and
receiving of transmission data with a timer.
Protocol selection (y10)
Data for y10 Protocol
0 Modbus RTU protocol
1 FRENIC Loader protocol
y10 specifies the communications protocol
for the standard RS-485 port.
For FRENIC Loader (via the RS-485
communications link), only y10 can be used
for protocol selection. Set the y10 data to "1."
