Group 15: Analog Outputs

This group defines the drive's analog (current signal) outputs. The drive's analog
outputs can be:
• Any parameter of the Operating Data group (Group 01).
• Limited to programmable minimum and maximum values of output current.
• Scaled (and/or inverted) by defining the minimum and maximum values of the
source parameter (or content). Defining an maximum value (parameter 1503 or
1509) that is less than the content minimum value (parameter 1502 or 1508)
results in an inverted output.
• Filtered.
Code Description
1501 AO1 CONTENT
Defines the content for analog output AO1.
99 = – Provides a current source for sensor type PTC. Output = 1.6 mA. See Group 35.
EXCITE PTC
100 = 100 – Provides a current source for sensor type Pt100. Output = 9.1 mA. See Group 35.
EXCITE PT
101...145 – Output corresponds to a parameter in the Operating Data group (Group 01).
• Parameter defined by value (value 102 = parameter 0102)
1502 AO1 CONTENT MIN
Sets the minimum content value.
• Content is the parameter selected by parameter 1501.
• Minimum value refers to the minimum content value that will be
converted to an analog output.
• These parameters (content and current min. and max. settings)
provide scale and offset adjustment for the output. See figure.
1503 AO1 CONTENT MAX
Sets the maximum content value
• Content is the parameter selected by parameter 1501.
• Maximum value refers to the maximum content value that will
be converted to an analog output.
1504 MINIMUM AO1
Sets the minimum output current.
1505 MAXIMUM AO1
Sets the maximum output current.
1506 FILTER AO1
Defines the filter time constant for
• The filtered signal reaches 63% of a step change within the time
specified.
• See figure in parameter 1303.
1507 AO2 CONTENT
Defines the content for analog output
1508 AO2 CONTENT MIN
Sets the minimum content value. See
1509 AO2 CONTENT MAX
Sets the maximum content value. See
1510 MINIMUM AO2
Sets the minimum output current. See
1511 MAXIMUM AO2
Sets the maximum output current. See
1512 FILTER AO2
Defines the filter time constant for AO1. See
