‑118‑
Name Model Function Remarks
Resolver interface card MD38PG4 Applicable to the resolver. Excitation
frequency: 10 kHz; DB9 interface.
To meet the MD38PG4 requirements, the
excitation input DC resistance of the resolver
must be greater than 17 Ω. Failure to comply
may result in MD38PG4 exceptions. Select a
resolver with a maximum of four pole pairs.
Otherwise, MD38PG4 will be overloaded.
Applicable to all models
MD38PGMD multi‑
function encoder card
MD38PGMD Collector and differential encoder interface
card with an optional multiplied frequency‑
division output; adaptable to 5 V/15 V power
supply.
Supports differential input, collector input,
and push‑pull input; supports differential
output and collector output; supports a
variety of interfaces such as encoder
interfaces and host controller A/B phase input
interfaces.
Applicable to all models
23‑bit PG card ES510–PG‑CT1 Applicable to 23‑bit encoder of Inovance; with
a DB9 interface
Applicable to all models
6.2 Installing the Expansion Card
The AC drive has three I/O expansion cards, one PC programmable card, seven field
bus cards (Modbus‑RTU, PROFIBUS DP, CANlink, CANopen, PROFINET, EtherCAT, and
Ethernet/IP), and three PG cards. Their installation positions are shown in the figure
below. Before installing these cards, remove the front cover of the AC drive.
