SETTING CURRENT POSITION ON 2090
The total travel between the mechanical limits is between 370 and
400 degrees. This is fixed by the engagement mechanism inside
the drive unit and is non-adjustable. Set the 0 degree position on
the 2090 so that the 2090 moves the table between the mechanical
limits without engaging them in normal operation.
EXAMPLE (CW - clockwise, CCW - counterclockwise)
The table is rotated CCW until it stops at the mechanical limit. The
table current position is then set at 0. Then it is rotated CW till it
stops at the CW mechanical limit switch. The controller now reads
385 degrees which is the full travel between mechanical limits.
The current position on the 2090 is then reset to 360 about 10-15
degrees from the CW mechanical limit. This will keep it from
hitting both mechanical limits when rotating from 0 to 360 during
operation by the 2090.
CAUTION: ON RESETTING CURRENT
POSITION ON 2090
The stopped position of the TT platform at 0 degrees may drift
overtime depending on usage. The 0 degree position of the 2090
controller is fixed with respect to the mechanical limits described
in the “SETTING CURRENT POSITION ON 2090” section if
they are not disabled per the instructions in the “CONTINUOUS
ROTATION / DISENGAGING MECHANICAL LIMIT
SWITCHES” section.
The platform can be rotated periodically back to a desired position
and the 2090 current position can be reset to 0 only if the
mechanical limits are disabled. The CW and CCW limits on the
2090 will continue to function with the mechanical limits disabled.
If the mechanical limits remain in operation, the 360 travel on the
2090 will no longer be between mechanical limits and normal
operation will be interrupted if they are not disabled per the
instructions in the “CONTINUOUS ROTATION /
DISENGAGING MECHANICAL LIMIT SWITCHES” section.
