0: positive characteristic

1: negative characteristic

The positive characteristic is effective when the terminal is engaged and void when

the terminal is disconnected. The negative characteristic is effective when the term-

inal is disconnected and void when the terminal is engaged.

Output terminal OC function selection

Relay output TA/TC function selection

Setting range: 0 ~ 15

It is used to define the contents indicated by the collector open-circuit output termi-

nal OC and relay output contact. See Figure 6-8 for the internal wiring diagram of

the collector open-circuit output terminal. When the function is set to be effective,

the output is at low level, and when the function is void, the output is at the high-

resistance status.

Relay contact output: when the output function is set to be effective, the normally

open contact TA-TC is connected.

For connecting external inductive elements (e.g. relay coil),

freewheel diode D must to be connected in parallel.

0: Inverter is running

When the inverter is running, it outputs effective signals, and when the inverter is

at stop, it outputs void signals.
