Parameters
7.2 Parameter list
Description:
Control and feedback signals of the bypass switch.
Bit field:

10
11
Dependency:
The "Bypass" function is only available for induction motors.
Note
Control bits 0 and 1 should be interconnected to the signal outputs via which the switches in the motor feeder cables
should be controlled. These should be selected/dimensioned for switching under load.
p1262[0...n]
Bypass dead time / Bypass t_dead
Access level: 2
Can be changed: T, U
Unit group: -
Min:
0.000 [s]
Description:
Sets the dead time for non-synchronized bypass.
Dependency:
The "Bypass" function is only available for induction motors.
Note
This parameter is used to define the changeover time of the contactors. It should not be shorter than the de-magnetizing
time of the motor (p0347).
The total changeover time for the bypass is based on the total of p1262 plus the OFF time for the relevant switch
(p1274[x]).
p1263
Debypass delay time / Debypass t_del
Access level: 2
Can be changed: T, U
Unit group: -
Min:
0.000 [s]
Description:
Sets the delay time to switch back to converter operation for a non-synchronized bypass.
Dependency:
The "Bypass" function is only available for induction motors.
p1264
Bypass delay time / Bypass t_del
Access level: 2
Can be changed: T, U
Unit group: -
Min:
0.000 [s]
Description:
Sets the delay time for switching to line operation for a non-synchronized bypass.
Dependency:
The "Bypass" function is only available for induction motors.
