20.21 Direction 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 20.21 Direction and Direction command (from DI
configured in 20.01 Ext1 commands or 20.06 Ext2 commands
and its related parameters).
Request
Request Refer the table above for rotation direction of motor. 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
20.22 Enable to rotate 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 06.16 Drive status word 1 is set to 0.
