7.1.4 DXC-EXT-LOCSIM simulator
Figure 96:
DXC-EXT-LOCSIM
DXC-EXT-LOCSIM is a simple commissioning and test simulator for DC1
variable frequency drives.
Three microswitches and a PCB mount potentiometer make it possible to
easily put the variable frequency drive into operation “out of the box” based
on the corresponding help cards when using the drive’s default settings
Section 4.6 “Help cards”, page 133.

Block diagram DXC-EXT-LOCSIM simulator
The three microswitches can be used to directly drive (from left to right) the
three digital inputs DI1, DI2, and DI3 with the internal control voltage (24
VDC). Meanwhile, the POTI PCB mount potentiometer can be turned
clockwise to sets the frequency reference value (0 - 50 Hz).
The analog output signal from AO (0 - 10 VDC) will be available at control
signal terminals 8 and 9 as per the output frequency (0 - 50 Hz).
