Analog Outputs Section 7-10
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.
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
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
adjustment
The output values can be offset as required for the connected device.
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
Item Specification
Condition 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-
ule (such as flash memory errors not listed
above, FALS, etc.)
The output status specified by
the hold function (clear, peak,
or hold) will be output.
