6. 5. Monitored parameters

It is possible to select up to 4 parameters to display their values in the [1.2 - MONITORING] menu ([COMMUNICATION MAP] submenu) on the graphic display terminal.

The selection is made via the [6 – MONITOR CONFIG.] menu ([6.3 - CONFIG. COMM. MAP] submenu).

Each parameter [Address 1 select] ... [Address 4 select] can be used to choose the logic address of the parameter. Select an address of zero to disable the function.

In the example given here, the monitored words are:

•Parameter 1 = Motor current (LCr): logic address 3204; signed decimal format

•Parameter 2 = Motor torque (Otr): logic address 3205; signed decimal format

•Parameter 3 = Last fault occurred (LFt): logic address 7121; hexadecimal format

•Disabled parameter: address 0; default format: hexadecimal format

One of the three display formats below can be assigned to each monitored word:

	RDY	NET		+0.00Hz		0A

	6.3 CONFIG. COMM. MAP.

Address 1 select			:			3204
FORMAT 1			:			Signed
Address 2 select			:			3205
FORMAT 2			:			Signed
Address 3 select			:			7121

	Code					Quick

FORMAT 3			:			Hex
Address 4 select			:			0
FORMAT 4			:			Hex

Format	Range	Terminal display
Hexadecimal	0000 ... FFFF	[Hex]

Signed decimal	-32,767 ... 32,767	[Signed]

Unsigned decimal	0 ... 65,535	[Unsigned]
