Process data (PDO)
The real time data transfer is performed by means of using the “Process Data Objects.” The transfer of PDOs is performed
with no protocol overhead. The Process Data is time-critical data used for control of the drive and monitor status.

Some drive actual values can be monitored by using a Process Data Object 2 (rx).
ote:N PDO1 and PDO2 should be used when in “Drive Mode” and PDO3 and PDO4 used in “Bypass Mode”.
vl_actual percentage Motor Speed. Scaled with percentage function
_torque_percentage Calculated torque. Scaled in 0.0%–100% (0–1000)
_current_percentage Measured motor current. (1 = 0.01 A)
fault_code Shows the drive fault code (= 0, if no fault active)
