Siemens SINAMICS G120X - Bypass Dead Time; Bypass T_Dead; Bypass Delay Time; Bypass T_Del; Debypass Delay Time; Debypass T_Del

Description: Control and feedback signals of the bypass switch.
Bit field: Bit Signal name 1 signal 0 signal FP
00 Command switch motor - power unit Close Open -
01 Command switch motor - line supply Close Open -
05 Feedback signal switch motor - power unit Closed Opened -
06 Feedback signal switch motor - line supply Closed Opened -
07 Bypass command (from p1266) Yes No -
10 Bypass in process sequence Yes No -
11 Bypass enabled Yes No -
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 Calculated: CALC_MOD_REG Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0.000 [s]
Max:
20.000 [s]
Factory setting:
1.000 [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 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
0.000 [s]
Max:
300.000 [s]
Factory setting:
1.000 [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 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
0.000 [s]
Max:
300.000 [s]
Factory setting:
1.000 [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.
