[‘COMM_CONN’ Sequence]
EXT_DCBR:
DC Injection Braking can be activated, while the
inverter is stopped, by configuring one of the multi-
function input terminals to ‘EXT_DCBR’. To
activate the DC Injection Braking, close the contact
on the assigned terminal while the inverter is
stopped.
Example:
If P4 is configured as EXT_DCBR, then DC injection braking is
achieved on stop by using P4 input terminal.
[External DC-braking in stop]
EXT_TRIP:
This is a normally closed contact input. When an
input terminal is set to ‘EXT_TRIP’ and the contact
input opens, the inverter displays the fault and cuts
off its output. This can be used as an external latch
trip. The inverter will decelerate as configured in
[FUN 15]. The inverter must be RESET and the
RUN command must be re-initiated to restart the
drive.
