DANGER
Without the permission or authorization by A-TS Technology, no motor or
motor encoder shall be matched with RT20 servo drive. Otherwise, it may
cause damage to the motor or even danger to personal safety.
INSTRUCTIONS
When using an absolute motor, choose the encoder terminal CN4.
Terminal CN5 supports standard incremental and ABZ incremental encoder.
When the encoder cable is longer than 10 meters and the signal cable
diameter is not greater than 24AWG, two power signal cables must be
connected in parallel.
