Up to 5 outputs (2 of which are relays), which can be freely programmed with digital functions are
available in the SK 54xE. These can be seen in the following table.
[-01] = Output 1 / MFR1, relay output 1: external brake, (default), Terminals 1/2
[-02] = Output 2 / MFR2, relay output 2: Fault, (default), Terminals 3/4
[-03] = Output 3 / DOUT1, digital output 1: No function, (default), Terminal 5
[-04] = Output 4 / DOUT2, digital output 2: No function, (default), Terminal 7

Following a stop signal and the braking ramp, a direct current is briefly applied to the motor to
fully bring the drive to a stop. Depending on the inertia, the time for which the current is applied
can be set in this parameter.
The current level depends on the previous braking procedure (current vector control) or the static
boost (linear characteristic).

Digital input 7 (DIN7) can also be used as digital output 3 (DOUT3 / Binary output 5). It is recommended that either an input function (P420 [-07] or an out-
put function (P434 [-05]) is parameterised. However, if and input function and an output function are parameterised, a High signal from the output function will
result in the activation of the input function. This IO-exclusion is hence used as a kind of "flag". This also applies for digital input 8 (DIN8) and digital output 2
(DOUT2 / binary output 4).
