●
Use twisted pair cables for the same encoder tracks, e.g. A + / A -.
●
Lay the cable shield on both sides at the encoder and inverter connector.
Connecting a TTL encoder to -X25
All encoder signals have a voltage level compliant with RS 422.
The encoder connection on the inverter side is a high density socket.
●
Only use this encoder for field-oriented control with a speed accuracy < 1 %.
●
Connect the encoder mechanically rigid to the motor.
●
Do not place any gearbox between encoder and motor.
