2.2 List of parameters
Description: Sets the OFF delay for the auxiliaries.
The switching off of the auxiliaries in relation to that of the line contactor is delayed by the time set here.
Description: Sets the wait time for a contactor in the DC circuit.
The time set in p50095 starts to elapse during a switch-on operation when operating state o5 is reached.
If this time is still running when operating state o4 is exited, then the system stays in state o3.2 until this time lapses.
Dependency: Refer to: p50691
Notice: If the motor is connected to the DC current output (terminal 1C1, 1D1) via a contactor, then generally, this contactor
is also controlled from the relay for the line contactor (terminals 109, 110). In this case, it must be ensured that the
firing pulses are only enabled after it is completely certain that the contactor has closed. To realize this, this additional
wait time is required when switching on.
Note: If the function "Feedback line contactor" is used, a change to 1 signal must be detected via p50691 within the time set
in p50095. Otherwise, state o3.3 is adopted until it elapses and afterwards fault F60104 is triggered with fault value 6.
Description: Sets the run-on time for the device fan(s).
After a pulse inhibit (reaching an operating state >= 0.9), the device fan(s) run-on until the power unit has cooled
down and until the run-time has expired.
The power unit is considered to have been cooled down if all of the following conditions apply:
- All temperature sensors of the power unit indicate values less than 35 °C.
- The thermal model for the thyristors supplies a value of less than 5 %.
- The field current is less than 10 A.
Dependency: Refer to: r53135
Refer to: F60167
Description: Sets the response of the field current to faults.
