Wiring
Wire the motors encoder wires to the encoder card using the below reference table.
Terminal
Function
S
Shield connection
A+
Positive A channel pulse (A)
A-
Negative A channel pulse (/A)
B+
Positive B channel pulse (B)
B-
Negative B channel pulse (/B)
G
Ground connection, common for DC supplies below.
5V
5VDC supply to encoder
12V
12VDC supply to encoder
15V
15VDC supply to encoder
RTA/RTB
Return Pulse for channel A and B (open collector
output)
The encoder card supports line driver type and open collector type encoders. Be sure to set the switch pictured below to
the correct setting depending on the applied encoder.
Parameter Setup
It is imperative to setup the below parameters and conduct and autotune to ensure proper operation of the iS7 with
encoder feedback.
