Hello everybody
I am trying to read the values from a direct drive linear motor's (SDLM-025-095-01-05) inbuilt encoder using a NUCLEO-F446RE board. It is a straight forward task, but I am slightly confused with the cables. (
datasheet )
Overall, the motor itself has 10 cables (as seen in the datasheet + transcription below). Since I just want to read the encoder values, and the negative channels, aka wires Blue & Yellow should not be touched (mentioned by the manufacturer), how should I connect the wires to my Nucleo board?
I understand I need 4 wires:
Orange for
Power,
Green and
White for the
2 Channels and finally the
ground. But which wire is that? Is it Brown? I understand that the Black wire is the minus for the motor.
1.
Orange - +5 VDC Power for optical encoder
2.
Green - Channel A+ Output of optical encoder, TTL
3.
Blue - Channel A- Output of optical encoder, TTL
4.
White - Channel B+ Output of optical encoder, TTL
5.
Yellow - Channel B- Output of optical encoder, TTL
6.
Brown - Return for optical encoder and thermistor
7.
Black - Motor minus
8.
Red - Motor plus
9.
Gray - Home indicator, TTL, Active high
10.
Purple - Thermistor relative to Earth.
