PO2: Setpoint speed
If the adjusted operating mode (P700/P701 Operating mode 1/2) allows a speed set-
point, the power section "PFA-..." interprets the transferred numerical value as a
speed setpoint.
If no speed setpoint is programmed although a communication interface (fieldbus) has
been set as setpoint source, the power section runs at speed setpoint = 0.

PO3: Ramp
The power section "PFA-..." interprets the transferred setpoint as a run-up or run-down
ramp. The transferred time value refers to a change in speed of 3000min
-1
. The stop
and emergency stop functions are not affected by this process ramp. When transmit-
ting the process ramp via fieldbus system, ramps t11, t12, t21 and t22 become inef-
fective.

PI1: Status word
The status word of the speed-controlled drive is used to display the device status and,
in case of a fault, the respective fault number.
The status word is defined as follows:
Speed-controlled drive status word (2 bytes)
Bit Meaning Coding and function
0 Output stage enabled
1 = Output stage enabled.
0 = Output stage not enabled.
1 Inverter ready
1 = Power section "PFA-..." is ready.
0 = Power section "PFA-..." is not ready.
2 PO data enabled
1 = Process data is enabled. The drive can be con-
trolled via fieldbus.
0 = Process data is inhibited. The drive cannot be con-
trolled via fieldbus.

0 = Integrator set 1
1 = Integrator set 2
4 Current parameter set
0 = Parameter set 1
1 = Parameter set 2
5 Fault/warning
1 = Failure/warning present.
0 = No failure/warning present.
