Functions

 

Slope

The ACC(888) instruction can be used to change the analog output value at the follow-

 

 

 

ing rates:

 

 

 

 

 

–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)

 

 

 

 

 

 

 

 

Output hold

The output stop function will clear the output, hold it at the peak value, or hold it at the

 

 

 

current value in the following cases.

 

 

 

 

• One of the Analog Output SV Error Flags is ON. (A562.08 is the flag for output 1 and

 

 

 

A563.08 is the flag for output 2.) (Only when end refresh is selected.)

 

 

 

• A fatal error (other than a Motion Control Module WDT error or flash memory adjust-

 

 

 

ment data error) occurred in the Motion Control Module. (See note 2.)

 

 

 

• The other analog output is being adjusted in adjustment mode.

 

 

 

 

 

 

 

 

Offset/gain

The output values can be offset as required for the connected device.

 

 

adjustment

In adjustment mode, the offset or gain can be changed by turning ON the Adjustment

 

 

 

 

 

 

Enable Bit (A570.00 for the analog input, A570.01 for analog output 1, or A570.02 for

 

 

 

analog output 2), specifying the offset or gain value, and turning ON the Increment or

 

 

 

Decrement Bit from the CX-Programmer.

 

 

 

 

• Offsets:

–10 to 10 V: FE0C to 01F4 hex

 

 

 

 

 

 

0 to 10 V, 0 to 5 V, or 1 to 5 V: FF38 to 00C8 hex

 

 

 

• Gain values: –10 to 10 V: 1194 to 157C hex

 

 

 

 

 

 

0 to 10 V, 0 to 5 V, or 1 to 5 V: 0ED8 to 1068 hex

 

 

 

 

 

 

 

 

Note

(1) The overall accuracy is the ratio of accuracy to the full scale.

 

 

 

(2) The following table shows the status of the analog outputs if there is a fa-

 

 

 

 

tal error in the Motion Control Module or the Coordinator Module is in

 

 

 

 

CPU standby status.

Analog output

 

 

 

 

 

 

 

 

 

 

WDT error in Motion Control Module

Output near 0 V (0 V output

 

 

 

 

 

 

without offset adjustment).

 

 

 

 

• Flash memory adjustment data error in

 

 

 

 

 

 

 

 

 

 

Motion Control Module (flash memory error or

 

 

 

 

 

 

adjustment data error indicated in Auxiliary

 

 

 

 

 

 

Area)

 

 

 

 

 

• CPU standby error in Coordinator Module

 

 

 

 

 

 

 

 

 

 

 

Another fatal error in the Motion Control Mod-

The output status specified by

 

 

 

 

ule (such as flash memory errors not listed

the hold function (clear, peak,

 

 

 

 

above, FALS, etc.)

or hold) will be output.

If there is an error in the System Setup settings for the analog output func- tion (Analog Input/Output), the following settings will be used.

Output range:

– 10 to 10 V

Output stop function:

Clear

Refreshing method:

END refresh
