Preventing Reduced Dynamic Control Performance
To prevent reduced dynamic control, you should take normal motion system precautions and
monitor the drive's motor capacity.
Normal motion system precautions include:
•
Interlocks for access.
•
Range of motion hardware and software limits.
•
Use Motion Analyzer to size your Motor/Drive combination with sufficient margin. We
recommend that you monitor motor capacity when commissioning the axis.
Additionally, you should monitor the drive's motor capacity in case of unexpected obstruction or
axis mechanical failures. Take the following steps to monitor the motor capacity:
•
Make sure the Position Error Tolerance is set appropriately for your axis.
•
Turn on Motor Capacity Real Time Attribute on the Axis Properties Drive/Motor tab.
•
Determine your worst case expected axis.MotorCapacity during normal axis operation.
•
In your application run-time code, monitor the axis.MotorCapacity real time attribute.
Drive Foldback occurs when axis.MotorCapacity reaches 108% of rated continuous
torque.
•
Implement a program that brings your axis to a controlled stop before
axis.MotorCapacity reaches 100%.
