Adjusting settings in the inverter

Procedure

Make the following settings and releases so that the inverter can accept commands from

the panel:

– Set the two signal sources for OFF2 (p0844 and p0845) to 1:

p0844 = 1

p0845 = 1

– Set the two signal sources for OFF3 (p0848 and p0849) to 1:

p0848 = 1

p0849 = 1

– Set the releases for the ramp-up encoder

p1140 = 1

p1141 = 1

– Set the setpoint release

p1142 = 1

Adjust the parameters for the ON/OFF1 command from the SIMATIC panel

– Set p0840[0] = 2094.0

In doing so, you connect up the ON/OFF1 command using the Bit 0 of the BiCo

transformer 2094. The signal source for this parameter is p2099.

– Now set p2099[0] = p2900

In doing so, you give the ON/OFF1 command by setting P2900 = 1 (ON) or 0 (OFF1)

Set parameters for the setpoint default

– Set

P1070 = 1001 (fixed setpoint 1 as setpoint)

P1016 = 1 (direct selection of the speed setpoint)

P1020 = 1 (speed fixed setpoint selection, Bit 0)

Actual value and status word

No further settings are required by the inverter for displaying the speed list value (r0021)

and the status word (r0052).

You have now made the settings in the inverter.
