Parameters
List of Parameters
p1260 Bypass configuration / Bypass config
Access level: 2
Can be changed: T
Units group: -
Min
0
Description: Sets the configuration for the bypass function.
Value: 0:
3:
Note: When the converter is switched on, the state of the bypass contactor is evaluated. If the automatic restart is active
(p1210 = 4) and both an ON command (r0054.0 = 1) and the bypass signal (p1266 = 1, configuration p1267.0 = 1)
are still present during power-up, the converter goes into "ready for operation and bypass" state (r0899.0 = 1 and
r0046.25 = 1) after power-up, and the motor continues to run directly on the line.
The "bypass" function can only be switched off again (p1260 = 0) if the bypass is not active or the bypass function
has a fault.
The flying restart function must be activated (p1200).
r1261.0...7 CO/BO: Bypass control/status word / Bypass STW / ZSW
Access level: 2
Can be changed: -
Units group: -
Min
-
Description: Control and feedback signals of the bypass switch.
Bit field: Bit Signal name
00 Command switch motor - drive
01 Command switch motor - line supply
05 Feedback signal switch motor - drive
06 Feedback signal switch motor - line supply
07 Bypass command (from p1266)
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: U, T
Units group: -
Min
0.000 [s]
Description: Sets the dead time for non-synchronized bypass.
Note: This parameter is used to define the changeover time of the contactors. It should not be shorter than the de-magne-
tizing 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: U, T
Units group: -
Min
0.000 [s]
Description: Sets the delay time to switch back to converter operation for a non-synchronized bypass.
