Analog Outputs
Rockwell Automation Publication PFLEX-RM001H-EN-P - June 2013 31
Here, the deadband is “shifted” due to the 50 Hz limitation. The command
frequency from 0 to 3 volts on the analog input will be 15 Hz. After 3 volts, the
frequency will increase at a rate of 0.2 volts per hertz up to 9 volts. After 9 volts
on the analog input the frequency command will remain at 45 Hz.
Analog Outputs Explanation
Each drive has one or more analog outputs that can be used to annunciate a wide
variety of drive operating conditions and values.
The user selects the analog output source by setting [Analog Out Sel].
Configuration
The PowerFlex 70 standard I/O analog output is permanently configured as a
0-10 volt output. The output has 10 bits of resolution yielding 1024 steps. The
analog output circuit has a maximum 1.3% gain error and a maximum 7 mV
offset error. For a step from minimum to maximum value, the output will be
within 0.2% of its final value after 12ms.
