p1265 Bypass speed threshold / Bypass n_thresh
Access level: 2 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: p2000 Dynamic index: -
Unit group: 3_1 Unit selection: p0505 Function diagram: -
Min:
0.00 [rpm] Max:
210000.00 [rpm] Factory setting:
1480.00 [rpm]
Description: Sets the speed threshold to activate the bypass.
Dependency: The "Bypass" function is only available for induction motors.
If the drive setpoint speed is entered via a motorized potentiometer, then the configuration bit p1030.4 should be set
in order to ensure the bypass via speed threshold function.
Note
When selecting p1260 = 3 and p1267.1 = 1, the bypass is automatically activated when this speed is reached.
The bypass speed threshold is only effective for positive directions of rotation. If the drive connected to the line supply
requires negative speeds, then this can be achieved using p1820 (direction of rotation reversal).
p1266 BI: Bypass control command / Bypass command
Access level: 2 Calculated: - Data type: Unsigned32 / Binary

Description: Sets the signal source for the control command to the bypass.
Dependency: The "Bypass" function is only available for induction motors.
p1267 Bypass changeover source configuration / Chngov_src config
Access level: 2 Calculated: - Data type: Unsigned8

Description: Sets the cause that should initiate the bypass.
Bit field: Bit Signal name 1 signal 0 signal FP
00 Bypass via signal (BI: p1266) Yes No -
01 Bypass via reaching the speed threshold Yes No -
Dependency: The "Bypass" function is only available for induction motors.
Note
The parameter only has an effect for a non-synchronized bypass.
p1267.0 = 1:
The bypass is initiated by setting a binary signal. When the command is reset, after the debypass delay time (p1263)
has expired, operation at the power unit is re-selected.
p1267.1 = 1:
When the speed threshold entered in p1265 is reached, the bypass is switched in. The system only switches back when
the speed setpoint again falls below the threshold value.
