High Message Rates

Some HMIs can send Modbus messages to drives at a very high rate. To allow the AKD2G drive to continue working it must regulate how fast it processes Modbus messages. If some Modbus messages are received too quickly the AKD2G slows down its response to some Modbus messages. The first few messages are replied to promptly, subsequent messages take longer to be responded to.

MODBUS.INFO reports the current message rate for each open connection and if the message rate is too high or if the message rate is throttled.
