Analog Output (AO) Setup
Analog outputs can be 0 to 10 V voltage outputs, or
they can be 0 to 100% duty cycle PWM outputs. They
usually come preprogrammed from the factory. An
analog output is wired to a physical pin, either PWM or 10
bit D/A. The source for an analog output can be mapped
from several places including mapping an analog input to
an output.
Analog Voltage Channels
• Channel ID 1 maps to connector pin BS3-9
• Channel ID 2 maps to connector pin BS3-10
Analog PWM Channels
• Channel ID 3 maps to connector pin BS2-15
• Channel ID 4 maps to connector pin BS2-16
• Channel ID 5 maps to connector pin BS2-17
• Channel ID 6 maps to connector pin BS2-18
• Channel ID 7 maps to connector pin BS2-19
• Channel ID 8 maps to connector pin BS2-20
• Channel ID 9 maps to connector pin BS2-21
The analog output screens display differently depending
on the type of output selected (Analog vs PWM). Figure
3-63 shows an example of analog output sourced from
an analog input.
1. Select channel ID by clicking on the channel ID
name in the Analog/PWM Output Diagnostics
screen (see Figure 3-63). The channel ID selects
the analog output pin where channel IDs 1-2 are
analog voltage and 3-9 are PWM pins.
2. Select the source type (A) as analog or control. A
different pick list will be displayed for each.
3. Select the function code (B) from the pick list.
4. Scale the output (C). Numbers are entered in the
units the source is measured in. Enter the value at
which the output should be 10 V . Enter the
value at which the output should be 0 V . This
scales the output voltage to the source (in source
units).
5. Check the “Enable” checkbox (D) to enable the
output.
6. Click “Apply Changes” (E).
Figure 3-63. Analog Output (AO) Mapping
1. Figure 3-64 shows an example of PWM output
sourced from an internal control source. Channel
ID 5 (A) is chosen by the user because it is a PWM
analog output type.
2. Select the source type (B) as analog or control. A
different pick list will be displayed for each.
3. Select the function code (C) from the pick list.
4. The module frequency (D) is fixed, and it depends
on the chosen channel. It is displayed as reference
only. The module frequency dictates the final PWM
frequency.
5. Select the Frequency prescaler (E) and PWM
counts (F) to set the final PWM frequency by the
indicated formula. The PWM counts value
