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]
- - - - - Float 3
Displays resultant maximum frequency.
P1300 < 20:
P1800 <= 6 kHz --> r1084 = min(P1082, P1800 / 15, 599.00)
P1800 >= 8 kHz --> r1084 = min(P1082, 599.00)
P1091[0...2] Skip frequency [Hz] 0.00 -
599.00
0.00 U, T - DDS Float 3
Defines skip frequency 1 which avoids effects of mechanical resonance and suppresses frequencies within
+ / -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] 0.00 -
599.00
0.00 U, T - DDS Float 3
Defines skip frequency 2 which avoids effects of mechanical resonance and suppresses frequencies within
+ / -P1101 (skip frequency bandwidth).
Note: See P1091
P1093[0...2] Skip frequency 3 [Hz] 0.00 -
599.00
0.00 U, T - DDS Float 3
Defines skip frequency 3 which avoids effects of mechanical resonance and suppresses frequencies within
+ / -P1101 (skip frequency bandwidth).
Note: See P1091
P1094[0...2] Skip frequency 4 [Hz] 0.00 -
599.00
0.00 U, T - DDS Float 3
Defines skip frequency 4 which avoids effects of mechanical resonance and suppresses frequencies within
+ / -P1101 (skip frequency bandwidth).
Note: See P1091

2.00 U, T - DDS Float 3
Delivers frequency bandwidth to be applied to skip frequencies.

frequency setpoint
- 0 T - CDS U32 /
Bin
3
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.
