2.5. Encoder Feedback Connections
One encoder feedback device must be used for all motor types, except for stepper motors.
Each of the two encoder channels in the Ndrive HL, accept a differential line driver
encoder, or with the -MXH option, the primary encoder channel, J207 accepts an analog
sine wave encoder. DC Brush and brushless motors may have a separate position and a
velocity feedback device. An analog sine wave encoder may be used with Aerotech’s
MXH multiplier box to multiply the encoder resolution and simultaneously convert it to a
differential line driver encoder signal, acceptable by the Ndrive HL.
Signal shielding is very important and the wiring should be
physically isolated from motor, AC power and all other
power wiring.
