Unit Description / Notes
When a current signal is used at the Analog Input AI4, set the switch
S2.1 on the EBA board to "ON".
Options 2 and 3 provide an inverse reference with which is possible to
have maximum speed with minimum reference.
Refer to P234.
[ 0.0 ]

0.0 to 16.0 It sets the time constant of the RC Filter of the Input AI2 (refer to figure
6.29).
[ 0.0 ]

Check possible options on table 6.40.
0 to 14
[ 2 ]
With factory default values (P251 = 2 and P252 = 1.000) AO1 = 10 V
-
when the motor speed is equal to the maximum speed defined at P134.
The AO1 output can be physically located on the control board CC9 (as a
0 V to 10 V output) or on the option board EBB (AO1', as a (0 to 20) mA/
(4 to 20) mA output). Refer to chapter 8.
0.000 to 9.999
Adjusts the gain of the AO1 analog output. For P252 = 1.000 the AO1
[ 1.000 ]
output value is set according to the description after figure 6.31.
0.001
Check possible options on table 6.40.
0 to 14
[ 5 ]
With factory default values (P253 = 5 and P254 = 1.000) AO2 = 10 V
-
when the output current is equal to 1.5 x P295.
The AO2 output can be physically located on the control board CC9 (as a
0 V to 10 V output) or on the option board EBB [(AO2', as a (0 to 20) mA/
(4 to 20) mA output)]. Refer to chapter 8.
Adjusts the gain of the AO2 analog output. For P254 = 1.000 the AO2
0.000 to 9.999
output value is set according to the description after figure 6.31.
[ 1.000 ]

0 to 63
Check possible options on table 6.40.
[ 2 ]
With factory default values (P255 = 2 and P256 = 1.000) AO3 = 10 V
-
when the motor speed is equal to maximum speed defined at P134.
For more information about the Analog Output AO3, refer to chapter 8.
