Inputs
2.15 Free analog input, signal selection
Selection of input signal of free analog input (an input not used for reference signal):
0 = Not in use
1 = Voltage signal V
in
2 = Current signal I
in
3 = Voltage signal A
in1
from terminals 202-203 of I/O Expander
4 = Analog signal A
in2
from terminal 204-205 of I/O Expander
- current signal SV9IOC100CN
- voltage signal SV9IOC102CN
2.16 Free analog input, function
This parameter sets the function of the free analog input:
0 = Function is not used
1 = Reducing motor current limit (par. 1.7). This signal will adjust the maximum motor
current between 0 and parameter max. limit set with parameter 1.7. See figure 6.2-4.
