OUT1
Multifunction programmable open collector output.
The terminal has been set by default so as to detect
and output low-speed signal output frequencies.
OUT2
Output
Multifunction programmable open collector output.
The terminal has been set by default so as to detect
and outputs signals indicating the completion of
acceleration/ deceleration.

Output
Relay contact output. Contact rating: 250 Vac = -2
A (cos = 1), 30 Vdc-1 A and 250 Vac-1A (cos =
0.4). Used to detect the activation of the inverter's
protective function. If the protective function is
activated, FLA-FLC circuit is closed, while FLB-FLC
circuit is opened .
