3 Functions
BI: Fct digital output 1
P0731=52.C
Defines the source for digital output 1.
NOTE
The brake relay can also be controlled
from another digital output (if this is
available) or using a distributed I/O
module. Analog to DOUT 1, it should
be guaranteed that the I/Os are
controlled by the status bit "MHB
active".
Inverting digital
P0748 = 0
outputs
This parameter allows the signals
to be output to be inverted.

Function
xxxx.y
Holding brake release delay (entered in s)
p1216 = ...
Defines the time interval during which the frequency inverter runs with the min. frequency
p1080 after magnetizing, before the ramp-up starts.
P1216 ≥ brake opening time + relay opening time
Holding time after ramp-down (entered in s)
p1217 = ...
Defines time for which inverter runs at minimum frequency (p1080) after ramping down.
P1217 ≥ brake closing time + relay closing time
