Description
"Analogue input function". Assignment of analogue functions to internal analogue
inputs or the analogue inputs of optional modules.
Note
The analogue inputs of the frequency inverter (analogue inputs 1 and 2) can
alternatively be parameterised to digital functions (see P420 [-13] or [-14]). To avoid
misinterpretation of the signals, the analogue functions can then be connected to the
relevant inputs (P400 [-01] or [-02])
Setting values
Value Function Description
00 Off
The analogue input has no function. After the FI has been enabled
via the control terminals, it supplies the set minimum frequency
P104.
01 Setpoint frequency
The specified analogue range (matching of analogue input) varies
the output frequency between the set minimum and maximum
frequencies P104/P105.
02 Torque current limit
Based on the set torque current limit P112, this can be changed by
means of an analogue value. 100 % setpoint here corresponds to
the set torque current limit P112.
03
Actual PID frequency
1)
Needed to set up a control loop. The analogue input (actual value)
is compared with the setpoint (e.g. fixed frequency). The output
frequency is adjusted as far as possible until the actual value
equals the setpoint (see control values P413...
P415).
04 Frequency addition
2)
The supplied frequency value is added to the setpoint.
05 Frequency subtraction
2)
The frequency value provided is subtracted from the setpoint.
