Speed controller Adjusting the speed controller:
Deselect "Pass over reference point" by setting MP1340 = 0.
Ensure that the loaded PLC program fulfills the following conditions:
• Position control loop is opened (W1038/W1128/W1040/W1132), because
the NC opens the position control loop only during the step function. If the
position controller is not optimized, error messages appear if the position
controller is closed.
• Servo drive controller is enabled (Module 9161)
• NC stop is inactive, MP4560 = 1
• Axis direction buttons active
• Axes clamped
In the MANUAL mode, use the oscilloscope function to select a step
function (approx. 500 mm/min) that will not overdrive the speed controller,
i.e. that does not limit I NOMINAL.
Display the nominal velocity value V (NOM RPM), the actual speed value V
(ACT RPM) and the nominal current value (I NOMINAL).
Activate the step function with the axis direction buttons.
To change the machine parameters, press the MP EDIT soft key in the
setup menu.
Increase MP2500.x (P factor) until the oscillation limit is reached.
MP2500.x at the oscillation limit
