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.
