Omron FQM1-CM001, FQM1-MMA21, FQM1-MMP21 operation manual Procedure

Analog Outputs Section 7-10

F: Analog output value

Specifies the target analog output value as a 4-digit hexadecimal value.

– 10 to		10 V	EA84 to 157C hex (–5,500 to 5,500 decimal, resolution:
			11,000)
0 to	10	V, 0 to 5 V,	FF38 to 1068 hex (–200 to 4,200 decimal, resolution: 4,400)
1 to	5 V

Note The specified analog output value must be within the allowed range listed above. If an out-of-range output value is specified, an error will occur and it will be necessary to switch to PROGRAM mode in order to output the analog output again.

ACC(888) can be used to generate a rising or falling analog output value

(@) ACC

P

#0000

T

P:Port specifier

(#0001 for analog output 1 or #0002 for analog output 2)

M:Always #0000

T = Rate of change, T+1 = Analog output target value

T = Rate of Change (4-digit hexadecimal)

T contains the rate of change (slope) per 2 ms.

–10 to 10 V	0000 to 2AF8 hex (0 to 11,000 decimal)
0 to 10 V, 0 to 5 V or 1 to 5 V	0000 to 1130 hex (0 to 4,400 decimal)

T+1 = Analog Output Target Value

T+1 is set to the target analog output value as a 4-digit hexadecimal value.

–10 to 10 V	EA84 to 157C hex
	(–5,500 to 5,500 decimal, resolution: 11,000)
0 to 10 V, 0 to 5 V or 1 to 5 V	FF38 to 1068 hex
	(–200 to 4,200 decimal, resolution: 4,400)

Note ACC(888) and SPED(885) cannot be used to change the analog output value while ACC(888) is generating a sloped output. Change the output value only after the target value has been reached.

7-10-5 Procedure

1,2,3... 1. Determine the analog output range, number of outputs, refreshing method, and instructions that will be used.

2.Wire the analog output.

3.Make the necessary System Setup settings (output method).

•Set the analog output range (−10 to +10 V, 0 to 10 V, 0 to 5 V, or 1 to 5 V).

•Set the output stop function (clear, peak value, or hold).

•Set the analog output refreshing method (END refresh or immediate refresh).

4.Create the necessary ladder programming.

•Set the output value in A560 or A561 with an instruction such as MOV.

•Execute SPED(885) or ACC(888).
