NOTE
After this parameter has been set, the power must be turned
off then back on for the setting to become effective.
[Data type] Bit axis
FSL The type of interface used between the servo amplifier and servo software is:
0 : Fast type.
1 : Slow type.
The user can choose between two interface types for servo data transfer:
fast type or slow type. Set this parameter so that the following conditions
are satisfied:
S When a one–axis amplifier is used, either the fast type or slow type
interface can be used.
S When a two–axis amplifier is used, the use of the fast type for both axes
is not allowed. The slow type can be used for both axes.
S When a three–axis amplifier is used, the requirement for a two–axes
amplifier described above applies to the first and second axes, and the
requirement for a one–axis amplifier, again described above, applies to
the third axis.
S When an odd number is specified for parameter No.1023, the fast type
interface must be used. However, the slow type may be used for high–
speed current loop axis and high–speed interface axis.
S When an even number is specified for parameter No.1023, only the
slow type interface can be used. (The FSL bit must always be set to 1.)
