SINAMICS DCP
296 List Manual (LH21), 05/2016
Description: Sets the operating mode for resistor precharging.
Value: 1: Resistor precharging side 1, up pulsing on side 2
2: Resistor precharging side 2, up pulsing on side 1
3: Resistor precharging both sides (side 1, side 2)
4: Resistor precharging both sides (side 2, side 1)
Dependency: Refer to: p55110
Refer to: F60058
Note: It is not permissible to set p55350 < 3 - and at the same time set p55110 > 0
Description: Sets the signal source for the target value for precharging using the "pulsing up" technique.
When precharging, the voltage is pulsed up to this target value.
Description: Sets the wait time for closing the precharging contactor.
Index: [0] = Side 1
[1] = Side 2
Description: Sets the wait time for closing the DC contactors.
Index: [0] = Side 1
[1] = Side 2
Description: Sets the tolerance for reaching the setpoint voltage for resistor or pulsing up precharging.
Index: [0] = Side 1
[1] = Side 2
