Description: Sets the ramp time for the DC link voltage (Vdc) when powering-up and powering-down.
Powering-up (pulses enabled, r0898.3 = 1):
During this time, the DC link voltage is increased from the rectifier value after pre-charging to the voltage setpoint
(p3510, p3511). The voltage setpoint is increased, when necessary, so that the modulation depth reserve (p3481)
is maintained. The reactive current is set to the value 0 while ramping.
Powering-down (inhibit pulses, r0898.3 = 0):
During this time, the DC link voltage is reduced to the rectified value (sqrt(2) * line supply voltage). The reactive cur-
rent value is set to the value 0 when the ramp starts.
Description: Sets the signal source of the active current setpoint for the closed-loop current control of the slave.
The signal value is received from the master infeed (e.g. via the mulitplexer or direct).
Dependency: Refer to: p3513, p3571, p3572, r3573
Description: Sets the signal sources for the input values of the multiplexer.
The signal values are used as setpoint for the closed-loop current control of the slave infeed.
Index: [0] = Multiplexer input value 0
[1] = Multiplexer input value 1
[2] = Multiplexer input value 2
[3] = Multiplexer input value 3
Dependency: Refer to: p3570, p3572, r3573
Note: For a master infeed and a slave infeed, the active current setpoint can be entered without using a multiplexer. If the
multiplexer for the master/slave is not required, then it can also be used for another function.
