2.21 Set Motor Home Check
Description
This command controls checking of the stepper motor synchronization .
When MotorHomeChk 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.
If this error is shown repeatedly, either there is a problem internal in the
LT360 or the torque load is too great for the drive system.
