P.053 Manual Reference Preset Enable
Parameter Range: OFF = Do not preset the manual reference
ON = Preset the manual reference with the auto reference at the transition from
AUTO to MANUAL.
Initial Setting: OFF
Type: Tunable (at rest or during operation)

Description: 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 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
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.
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.
Refer to chapter 3 for more information on the AUTO/MAN key and the AUTO LED.
