6.2.2 Model and specifications
6.2.2.1 Model
• There are two models for the PG interface expansion card, reflecting differences in the external
equipment output interface:
OPC-VG1-PG: Line driver signals
OPC-VG1-PGo: Open collector/voltage output
Take care not to specify the wrong model when placing an order for cards.
The available models of FRENIC-VG's PG options differ according to the external equipment output
interface (line driver output, open collector output/voltage output).
After purchase, the target application can be selected with SW1 on the option.
Model format:
OPC-VG1-PG
()
PD (pulse detection): For pulse detection
LD (line speed detection): For line speed detection
PR (pulse reference): For input of pulse train commands (pulse
train synchronous operation)
SD (speed detection): For motor speed detection
None: Line driver output model (provides PG broken wire detection
function when SD is selected)
o: Open collector output and voltage output model (no PG broken
wire detection function)
PG: Pulse generator interface expansion card
VG1 → FRENIC-VG inverter
Accessories
Spacers: 3
Screws (M3): 3
SW1 setting
For example, to perform speed control for a motor that includes a line driver output type encoder, you
would order the OPC-VG1-PG and select SD with the switches as the speed control application. To
perform synchronized operation based on received pulse trains, set the switches to PR.
