Hi everyone,

I receive a G120C 2,2kW today and i want to do the following:

Active motor forward with DI0
Change to reverse with DI1
Speed selection with AI0 (0 to 2300rpm)
Switch to fixed speed with DI2 (150rpm)

I used the default setting nº12 (standard I/O with analog setpont)

Everything is ok exept switching to the fixed speed.

Parameter are the following:
P1070: P755
P1016: 2
P1020: r722.2
P1001: 150

The r1024 parameter switch to 150 when DI2 on... But motor still run at the analog speed...

Any idea?

I'm afraid guys from Siemens didn't know all your fantasies when deciding default settings. Therefore r1024 has no influence on the speed setpoint with the default setting nº12 selected.

You can seek a default setting better suited to your needs or taylor it by yourself.

Here's the manual explaining controls internals of a G120C. Especially the Function diagrams part.
