Parameters
Group 15: ANALOG OUTPUTS
This group defines the drive’s analog (current signal) outputs. The drive’s analog
outputs can be:
• any parameter in Group 01: OPERATING DATA
• 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 a maximum value (parameter 1503 or
1509) that is less than the content minimum value (parameter 1502 or 1508)
results in an inverted output.
•filtered.
Group 15: Analog Outputs
Code Description Range Resolution Default S
1501 AO1 CONTENT SEL 99…178 1 103 (
OUTPUT FREQ)
Defines the content for analog output AO1.
99 = EXCITE PTC – Provides a current source for sensor type PTC. Output = 1.6 mA. See Group 35: MOTOR TEMP
MEAS.
100 =
EXCITE PT100 – Provides a current source for sensor type PT100. Output = 9.1 mA. See Group 35: MOTOR
TEMP MEAS.
101…178 – Output corresponds to a parameter in Group 01: OPERATING DATA.
• Parameter defined by value (value 102 = parameter 0102)
1502 AO1 CONTENT MIN Depends on selection - 0.0 Hz
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 the figure.
1503 AO1 CONTENT MAX Depends on selection - 60.0 Hz
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 0.0…20.0 mA 0.1 mA 4.0 mA
Sets the minimum output current.
