Speed set point settings in ACP LINK
The speed set point is send to the variable speed drive as an analog 0-10 V signal, coming from the electrical
panel IO-module. The speed set point in the ACP LINK PLC (output from M251 PLC to M172) is calculated in
the range 0 – 1000, which corresponds to 0 – 10V output from the M172 electrical panel IO-module. The
calibration of output is done on the ACP LINK HMI and must correspond to the calibration of the analog input
on the variable speed drive (see also section 9.2).
The formula used to calculate the output signal, based on the set point for the frequency is:
Output [0..1000] = frequency_setpoint [Hz] * A + B. Output “1000” equals 10V.
Standard recommended parameters are shown in table below:
