Motor Home Check
This feature allows checking of the stepper motor synchroniza-
tion . When
Motor Home Check
is set ON, the firmware
checks that the motor returns to its home position after each movement. If
disabled, no checking is performed. If checking is enabled and the motor
does not end its operation in the home position, an error message is shown
on the front panel display.
The stepper motor produces a specific number steps for a given amount of
platter rotation. The LT360 utilizes microstepping for additional precision
control. One particular phase of the motor is designated as the
Home
position. For any given platter rotation, the motor should always end in its
Home position.
In normal operation this error should never occur. If it does, the unit must
be powered off to clear the error, or this feature disabled. It is possible for
this error to be produced by noise in the stepper motor controller, or by the
load exceeding the torque capability thereby causing the motor to skip
steps.
