PSD Manager I/O Configuration

CODESYS Project

PSD Manager Settings

In PSD Servo Manager, configure the I/O Board

Encoder Mode = Encoder Input
Encoder Type = Step/Direction
Resolution = 10000 incr/rev
Setpoint Control Mode = Encoder position

These settings are stored in this config file and can be imported into PSD Manager

Complete the rest of the settings in PSD Manager including motor selection and download to the drive.

Note that the S/D encoder input resolution considers step rising and falling edge (2-fold) acquisition (=2 counts per S/D period). The GearIn Denominator is set =2. This allows the user to match the output resolution of the controller to match the input resolution set in PSD Manager in step 3 above.
