Setup and Use
The encoder interface is most effective if used in conjunction with the vector mode of operation. Refer to the X5
User’s Manual (Chapter 6) for information about using the vector mode. Three additional parameters are provided
to calibrate the encoder:
Parameter 219, Encoder Pulses per Revolution, can either be extracted from the encoder nameplate or the data
sheet supplied with it. Parameter 220, Encoder Filter Time, is used to filter the encoder signal in the event of noise.
Parameter 221 is for limiting the response of the drive, in the event of the loss of encoder signal.
Two other parameters are provided to allow more flexibility in encoder selection, and to improve PID application
usage:
Parameter 223, Encoder Type, allows the use of either quadrature or single-channel types of encoders.
Parameter 224, Encoder Range, improves PID application flexibility. This parameter should be used in situations
where the encoder feedback signal is not always directly proportional to the motor speed, for example, a winder
using an encoder mounted on an idler pulley feeding a winding spool. The PID may be attempting to maintain a
constant linear speed on the wound media, but as the diameter of the media on the spool changes, the motor turning
the spool needs to vary its speed to maintain the linear speed at the idler pulley.
When parameter 224 is set to 0, it is ignored, and the PID calculates the feedback percentage based on parameter
301, Maximum Frequency. When this parameter is set to a non-zero value, the PID uses instead Parameter 224’s
setting to calculate the feedback percentage.
Encoder feedback works similarly to an analog input as configured in parameters 850 (PID Configure), 851 (PID
Feedback), 852 (PID Prop Gain), 853 (PID Int Gain), and 859 (PID Derivative Gain). The “feed forward” options are
suggested for setting parameter 850. More specific details on each of the listed parameters can be found in the X5
User’s Manual (DPD 00089).
