Skip Frequency 4; Skip Frequency Bandwidth; Bi: Inhibit Neg. Freq. Setpoint - Siemens MICROMASTER 440 Parameter Manual

Parameter Description
P1094[3]

Skip frequency 4

CStat: CUT
P-Group: SETPOINT
Defines skip frequency 4 which avoids effects of mechanical resonance and suppresses frequencies within
+/- P1101 (skip frequency bandwidth).
Index:
P1094[0] : 1st. Drive data set (DDS)
P1094[1] : 2nd. Drive data set (DDS)
P1094[2] : 3rd. Drive data set (DDS)
Details:
See P1091 (skip frequency 1).
P1101[3]

Skip frequency bandwidth

CStat: CUT
P-Group: SETPOINT
Delivers frequency bandwidth to be applied to skip frequencies (in [Hz]).
Index:
P1101[0] : 1st. Drive data set (DDS)
P1101[1] : 2nd. Drive data set (DDS)
P1101[2] : 3rd. Drive data set (DDS)
Details:
See P1091 (skip frequency 1).
P1110[3]

BI: Inhibit neg. freq. setpoint

CStat: CT
P-Group: COMMANDS
This parameter suppresses negative setpoints. Therefore, modification of the motor direction is inhibited to
the setpoint channel.
Index:
P1110[0] : 1st. Command data set (CDS)
P1110[1] : 2nd. Command data set (CDS)
P1110[2] : 3rd. Command data set (CDS)
Common Settings:
0 = Disabled
1 = Enabled
Notice:
Where
- If a min. frequency (P1080) and a negative setpoint are given, the motor is accelerated by a positive
value in relationship to the min. frequency.
- This function does not disable the "reverse command functions" (e.g. Reverse, ON left); rather, a
reverse command causes motor to run in the positive direction only, as described above.
