Override 8: Sequence input signal (Reference value 47)

The rotation speed of the servomotor can be changed during operation.
This signal is enabled only for LS type.
 Function
The rotation speed can be changed with the multiplication designated with override 1/2/4/8 while
the override enable signal remains turned on. The speed can be increased up to 150 [%] of the
current rotation speed (within the maximum rotation speed).
The weight of the multiplication corresponding to override 1/2/4/8 can be changed with the
standard parameter.
This parameter is enabled for all rotation commands except for command pulse input (command
pulse ratio 1/2). The function and corresponding number are shown below.
 Parameter setting
To assign the override enable to IQ area (sequence input terminal), specify the corresponding
value ("43") to the input terminal function setting parameter.
Similarly, specify the corresponding value ("44" to "47") for override 1/2/4/8.
This signal is handled to be always turned off if it is not assigned to the sequence input terminal.
 Relevant description
(1) Override multiplication
The multiplication applicable while the
override enable signal remains turned on is
shown in the table on the right. If override
enable is turned off, the original speed (100
[%] traveling speed) becomes effective.
Signals not assigned to sequence input
terminals are assumed to be turned off.
