Parameter Function
Note: When using the setpoint source
Analog Input
•
USS
•
the setpoint frequency (in Hz) is cyclically calculated using
a percentage value(e.g. for the analog input r0754)
•
a hexadecimal value (e.g. for the USS r2018[1])
•
and the reference frequency P2000.
•
If for example P1082 = 80 Hz, P2000 = 50 Hz and the analog input is parameterized with P0757 = 0 V,
P0758 = 0 %, P0759 = 10 V, P0760 = 100 %, a setpoint frequency of 50 Hz will be applied at 10 V of the
analog input. When Quick Commissioning is carried out P2000 is changed as follows: P2000 = P1082.
r1084 Resultant maximum
frequency [Hz]
Displays resultant maximum frequency.
P1091[0...2] Skip frequency [Hz]
Defines skip frequency 1 which avoids effects of mechanical resonance and suppresses frequencies with-
in + / -P1101 (skip frequency bandwidth).
Notice: Stationary operation is not possible within the suppressed frequency range; the range is merely passed
through (on the ramp). For example, if P1091 = 10 Hz and P1101 = 2 Hz, it is not possible to operate
continuously between 10 Hz + / - 2 Hz (i.e. between 8 and 12 Hz).
Note: The function is disabled if P1091 = 0.
P1092[0...2] Skip frequency 2 [Hz]
Defines skip frequency 2 which avoids effects of mechanical resonance and suppresses frequencies with-
in + / -P1101 (skip frequency bandwidth).
Note: See P1091
P1093[0...2] Skip frequency 3 [Hz]
Defines skip frequency 3 which avoids effects of mechanical resonance and suppresses frequencies with-
in + / -P1101 (skip frequency bandwidth).
Note: See P1091
P1094[0...2] Skip frequency 4 [Hz]
Defines skip frequency 4 which avoids effects of mechanical resonance and suppresses frequencies with-
in + / -P1101 (skip frequency bandwidth).
Note: See P1091
P1101[0...2] Skip frequency band-
width [Hz]
Delivers frequency bandwidth to be applied to skip frequencies.
Note: See P1091
P1110[0...2] BI: Inhibit negative fre-
quency setpoint
This parameter suppresses negative setpoints. Therefore, modification of the motor direction is inhibited
to the set-point channel. If a minimum frequency (P1080) and a negative setpoint are given, the motor is
accelerated by a positive value in relationship to the minimum frequency.
