FM 453 Servo Drive / Step Drive Positioning Module

This test is only necessary in the case of servo drives (MD61 = 0).
Use the following flow chart to check that the speed assignment of the drive
corresponds to the parameterization in the machine data.
If you have carried out the “Check encoder actuation” startup step correctly,
with each traverse, the actual traversing velocity of the machine axis will be
shown on the “Velocity” display.
This test has to be conducted in order to ensure that the parameterized
K
v
factor is implemented with the correct value in the position control circuit.
Fine calibration is then possible in the “Optimize position control” startup
step with the aid of the K
v
factor checkback signal in the service data.
