6.Inverter Parameter Setup - The inverter has several settings related to ModBus communications. The table below lists them together. The Required column indicates which parameters must be set properly to allow communications. You may need to refer to the host computer documentation in order to match some of its settings.

C076	Communication error select		00…Trip (Error code E60)
			01…Decelerate to a stop and trip (Error code
		−	E60)
			02…Disable
			03…Free run stop (coasting)
			04…Decelerate to a stop
C077	Communication error time-out	−	Comm. Watchdog timer period,
			range is 0.00 to 99.99 sec.
C078	Communication wait time	9	Time the inverter waits after receiving a
			message before it transmits.
			Range is 0. to 1000. ms

NOTE: When you edit and store any of the parameters above, the inverter causes it to take effect immediately. ModBus transmission occurs only after you set the OPE/485 DIP switch to the “485” position and turn on the inverter again. Note that parameters C070 to C078 cannot be changed via the network. To edit them, you must disconnect the inverter from the ModBus and wait for about 30sec until the inverter’s internal keypad begin functioning. Then use this keypad to edit the parameters. Please don’t connect other external programming devices to RJ45 connector, because the bus mode is in RS485 mode. It may cause the inverter or external programming devices to be damaged when DIP switch is in “485” position.
