Closing brake conditions:
There are 2 conditions for closing the brake again. It’s enough that one
is true for the brake to close.
1. If there is no run command active and output frequency goes be-
low Close frequency limit (P4.17) or Close frequency limit in reverse
(P4.18), depending on direction of rotation.
OR
2. Output current has gone below Current limit (P4.19)
10.5 Digital inputs
(Control panel: Menu PAR

P5)
These parameters are programmed using the Closing brake conditions:
FTT-method (Function To Terminal), where you have a fixed input or output
that you define a certain function for. You can also define more than one
function to a digital input, e.g. Start signal 1 and Preset Speed B1 to DI1.
The selections for these parameters are:
0 =
Not used
1 =
DI1

DI2

P5.1 and P5.2 : See P2.4 (I/O start stop logic) for function
Reverse
The digital input only active when P2.4 (I/O start stop logic)=1.
The motor will run in reverse when the rising edge of P5.3 is happened.
