Fieldbus data input mapping
Fieldbus Data inputs from 1 to 5 can be configured, with parameters P11.9 - P11.12, as:
Table 14.
Process Data IN Description Note
Aux Control Word
b0: enable
b1: acc/dec ramp 2 selection
b2: freq reference 2 selection
b3: digital output 1 control
b4: digital output 2 control
• b0 Enable is considered only when
control place is the Fieldbus. It is
computed in AND with a possible
enable from digital input. Fall of
enable will cause coasting stop.
• b2 FreqRef2 Sel is considered only
when control place is the Fieldbus.
• functions related to bit1, b3 and b4
are available also when control
place is not the Fieldbus. Aux CW
must anyway be mapped onto a
PDI, by means of parameter P11.9.
PID Setpoint
active if P12.1 = 3, range 0 -
10000 as 0 - 100.00% of regula-
tion.
PID Actual value
active if P12.4 = 2, range 0 -
10000 as 0 - 100.00% of regula-
tion.
Analogue Out Cntrl
active if P5.1 = 8, range 0 -
10000 as 0 - 100.00% of output.
