Parameters 193
Reference direction lock. Defines the direction of the drive
rather than the sign of the reference, except in some cases.
In the table the actual drive rotation is shown as a function of
parameter
and Direction command (from
parameter
Request
In external control the direction is selected by a direction
command (parameter
or
).
If the reference comes from Constant (constant
speeds/frequencies), Motor potentiometer, PID, Speed ref
safe, Last speed reference, Jogging speed or Panel
reference, the reference is used as is.
If the reference comes from a fieldbus:
• if the direction command is forward, the reference is used
as is
• if the direction command is reverse, the reference is
multiplied by -1.
0
Forward
Motor rotates forward regardless of the sign of the external
reference. (Negative reference values are replaced by zero.
Positive reference values are used as is.)
1
Reverse
Motor rotates reverse regardless of the sign of the external
reference. (Negative reference values are replaced by zero.
Positive reference values are multiplied by -1.)
2
Setting this parameter to 0 stops motor rotating but does not
affect any other conditions for rotating. Setting the parameter
back to 1 starts motor rotating again.
This parameter can be used for example with a signal from
some external equipment to prevent the motor rotating before
the equipment is ready.
When this parameter is 0 (rotating of the motor is disabled),
bit 13 of parameter
is set to 0.
Not selected
0 (always off).
0
Selected
1 (always on).
1
DI1
Digital input DI1 (
, bit 0).
2
No.
