Analog setpoint value matching
The external setpoint signal can be specifically matched with para-
meters PNU A11 to A16, which are described below. A configu-
rable voltage or current setpoint range can be assigned to a confi-
gurable frequency range.
Furthermore, analog setpoint signal filtering can be adjusted using
PNU A16.

A11 Frequency with
minimum
setpoint value
– 0 to 360 Hz Here, the frequency that corresponds to the minimum voltage setpoint
value under PNU A13 is set.

A12 Frequency with
maximum
setpoint value
0 to 360 Hz Here, the frequency that corresponds to the maximum voltage setpoint
value under PNU A14 is set.
0.0
A13 Minimum
setpoint value
0 to 100 % The minimum setpoint value entered here relates to the maximum
possible voltage or current setpoint (10 V or 20 mA).
0
A14 Maximum
setpoint value
0 to 100 % The maximum setpoint value entered here relates to the maximum
possible voltage or current setpoint (10 V or 20 mA).

A15 Conditions for
start frequency
Determines the behaviour at setpoint values below the minimum setpoint value. 01
00 The frequency defined under PNU A11 is applied to the motor.
01 A frequency of 0 Hz is applied to the motor.
A16 Analog input
filter time
constant
To reduce the inverter’s response time to setpoint changes at the O or OI terminal, and
thereby determine the degree to which analog signal harmonics are filtered, you can enter
a value between 1 and 8 here.

1 Minimal filtering effect/fast response to setpoint value changes
....
8 Maximum filtering effect/slow response to setpoint value changes
