The analog input of the FC can be used for different functions. Please note that only one of
the functions described below can be used at a time.
If, for example, actual frequency PID has been selected, the frequency setpoint cannot be
an analog signal. The setpoint value can be specified for example by means of a fixed
frequency.
Analog functions:
0 = Off , the analog input is without function. After release of the FC via the control
terminals it will supply the minimum frequency if set (P104)
1 = Setpoint frequency; the specified analog range (P402/P403) varies the output
frequency between the set minimum and maximum frequency (P104/P105).
2 = Torque current limit ; based on the set torque current limit (P112) it can be
modified via an analog value. Here, 100% setpoint value correspond to the set
torque current limit P112. The value cannot fall below 20%
3 = Actual frequency PID* ; is needed to establish a control loop. The analog input
(actual value) is compared to the setpoint value (e.g. fixed frequency). The output
frequency is adjusted as far as possible until the actual value has approached the
setpoint. (see controlled variables P413 - P415).
4 = Frequency addition ** ; the supplied frequency value is added to the setpoint
value.
5 = Frequency subtraction ** ; the supplied frequency value is subtracted from the
setpoint value.
6 = Current limit ; based on the set current limit (P536) it can be modified via the
analog input.
7 = Maximum frequency; the maximum frequency of the FC is varied. 100%
corresponds to the setting in parameter P411. 0% corresponds to the setting in
parameter P410. The value cannot fall below the values for the min./max. output
frequency (P104/P105) or exceed them.
8 = Actual frequency PID limited * ; same as function 3, but the output frequency
cannot fall below the programmed value for minimum frequency in parameter P104.
(no rotation direction reversal)
9 = Actual frequency PID monitored * ; same as function 3, but the FC switches off
the output frequency when the minimum frequency P104 has been reached.
10 = reserved
11 = Rate-action torque; this function allows for teaching the controller in advance a
value for the torque requirement (feedforward control). In lifting gears with
separate load sensing function, this function can be used to ensure better load
transfer.
12 = reserved
13 = Multiplication; the setpoint value is multiplied with the specified analog value. The
analog value adjusted to 100% corresponds to a multiplication factor of 1.
