9.7.4.2 Digital inputs
Here, you can configure the 3 digital inputs DigIn 1, DigIn 2 und DigIn 3
of the converter. The menus are the same for all 3 digital inputs. For this
reason, the configuration options are explained for digital input 1 only:
Note: If the temperature monitor of the brake resistor is used (refer to Chapter 5.2.1.5) , the digital
input 2 can not be changed !
9.7.4.2.1 External fault acknowledgement
"
External fault acknowledgement input " function. A fault can be
acknowledged by an ex24V signal on this input.
9.7.4.2.2 Monitoring drive contactors
"
Monitoring drive contactors " function. This function is only required in
combination with our converter with integrated contactors. The drive
contactors are checked for a drop at a standstill (500 msec after opening
the ZS relay) via auxiliary contacts.
9.7.4.2.3 Monitoring of opening brake upon start
Function „ Monitoring of opening of brake upon start “. Via a +24 V
signal the VVVF controller is informed that the brake is open. The set
value will start only when the digital input switches to +24 V.
Note: If several digital inputs are programmed with this function, they all
must be at +24 V (AND link)
9.7.4.2.4 Brake monitoring as per EN81/A3
The VVVF controller is used for monitoring of the power brake according
