CHV180 series frequency inverter special for elevator Extension card
.85.
7.3.2.2 Terminals and DIP
There are 9 wiring terminals in asynchronous PG card:
+12V COM1
COM1
Figure 7.8 Wiring terminals in asynchronous PG card.
Among them, +12V and COM1 are the power supply output for the encoder; TERA+,
TERA-, TERB+ and TERB- are the input terminal for the encoder; TER-OA, TER-OB
and COM1 are the output terminal for frequency division signal and there is no PE in
the internal of the card, so the user can ground by themselves during use.
The frequency coefficient of asynchronous PG card is determined by the DIP switch on
the card. There are 8 switches and the frequency coefficient is decided by the shown
binary figures that are added by 1. ” 1” on the switch s the low bit and “8” is the high bit.
When the DIP is switched to ON, the bit is valid, reverse it is “0”.
