AC890PX Feedback Connections
Incremental Pulse Encoders
The default settings for the drive are for 2048 line,
quadrature, incremental pulse encoders with differential
outputs operating from a 10VDC supply.
•
Z channel (Marker pulse) connections are not
necessary for running the drive, but inputs are
provided for positioning and servo applications. The
supply voltage to the encoder is set in the Quick
Setup menu. Range 10 VDC to 20 VDC
Use the Keypad to set the following options:
Supply Voltage - PULSE ENC VOLTS
Number of lines per revolution - ENCODER LINES parameter
* Encoder direction - ENCODER INVERT
* Used to match the encoder direction to the motor direction. When TRUE, changes the sign of the
measured speed and the direction of the position count. It is necessary to set up this parameter when in
CLOSED-LOOP VEC mode, as the encoder direction must be correct for this mode to operate.
Using other types of encoders requires the 890 DSE Configuration Tool and the setting of other
parameters. Refer to the AC890PX Engineering Reference Manual for details of these parameters.
This section is only for closed loop vector and induction servo applications.
Skip this page if there is no encoder or resolver mounted on the motor.
Use 3-pair or 4-pair,
individually shielded encoder
cable, Belden model 8777 or
equivalent.
