CHV180 series frequency inverter special for elevator Extension card
.89.
TER-OA, TER-OB and COM1 are the signal terminals of frequency division output.
Note: PE terminal in PG card are not grounded to the earth, so users can
grounding it by themselves.
DB15 is the port of the encoder input signal. The sequence of the ports signal is as
below:

When using the synchronous PG card, it is necessary to insert the connecting wire of
SIN/COS or UVW whose signal array is corresponding with PG card into DB15 of PG
card.
The frequency division coefficient is determined by the dial switch on the card. The dial
switch consists of 8 bits. The frequency division is decided by the value of the binary
digits (at dial switch) plus 1. The bit marked as “1” on the DIP switch is the lower binary
bit, while “8” is the higher binary bit. When the dial switch is switched to ON, the bit is
valid, indicating “1”; otherwise, it is invalid, and it is indicating “0”.
Frequency division coefficients are shown in the table below:
