Description
Allows every stepper motor to be moved separately. This function
is useful to check out a specific motor or to perform an endurance
test after a repair.
You can select the Start and Stop positions of the test path, as well
as the motor Current, Speed, and Acceleration. You can specify a
Pause time. A Cycle Limit and Actual Cycle Counter are useful
tools for endurance tests.
Phase A: Verifies the functionality of the stepper motor. Manually
increase the current for tests. Use this item for troubleshooting
only.
Phase B: Verifies the functionality of the stepper motor. Manually
increase the current for tests. Use for troubleshooting only.
MicroStep Inx: Moves the motor within a range of up to four full
steps by applying the assigned current.
Warning: These items are typically used for service. If applied, do
not leave the test settings for longer than a few minutes. Leaving
the current setting in a critical range can damage the motor.
