Terminal Interfaces And Switches - INVT Goodrive390L Series User Manual

Goodrive390L Series Lift-Dedicated VFD
When the asynchronous motor uses the FVC mode, a PG card is a must. The
asynchronization PG card functions include processing circuits for two quadrature
encoder signals, receiving signals of differential, open collector, and push-pull encoders,
and encoder power supply output (+12V). Frequency-divided output can be performed
for the input encoder signals. The output quantity includes two channels of quadrature
open collector signals. You can choose according to your actual use.
A.3.2 Terminal interfaces and switches
The incremental encoder PG card has two 2*4P user wiring terminals. See the following

The frequency division coefficient of the incremental encoder PG card is determined by
the dip switch on the card. The dip switch have 8 bits, and the frequency division
coefficient is determined by adding 1 to the binary number that the dip switch represents.
The place labeled with "1" is the low binary bit, and the one labeled with "8" is the high
binary bit. When the dip switch is turned to ON, the bit is valid, indicating "1"; otherwise,
the bit indicates "0". See the following table for frequency division coefficients.
