4-42 GV3000/SE 230 VAC Drive, Software Reference Version 6.04
ATTENTION: The absolute value of the auto reference is used to
preset the manual reference. When this feature is enabled (P.053 =
ON), and the auto reference is a negative value, a direction change will
occur when the transition is made from AUTO to MANUAL. Verify that
the auto reference is a positive value and the FORWARD/REVERSE
command is appropriate to the application before making the transition
from AUTO to MANUAL. Failure to observe this precaution may result
in damage to, or destruction of, the equipment.
The absolute value of the auto reference is limited between Minimum Speed (P.003)
and Maximum Speed (P.004) before it is used to preset the manual reference.
Therefore, when this feature is enabled (P.053 = ON), and the auto reference is
negative value, a direction change will occur when the transition is made from
AUTO to MANUAL. Verify that the auto reference is a positive value and the
FORWARD/REVERSE command is appropriate to the application before making
the transition from AUTO to MANUAL.
Important: If the manual reference is being modified using the front-panel keypad/
display when the transition from AUTO to MANUAL is made, the
manual reference may not be preset with the auto reference.
Refer to chapter 3 for more information on the AUTO/MAN key and the AUTO LED.
