5.3.4 FSSB connection
(1) Case of one FSSB path
All axes connected with one FSSB path require setting to the same HRV control. Therefore, if Learning
HRV3 control is applied in one axis at least, other all axes require Servo HRV3 control.
(2) Case of two FSSB paths
Even if two FSSB path is used, all axes connected with each FSSB path require setting to the same HRV
control. Therefore, if Learning HRV3 control is applied in one axis at least, other all axes that include
another FSSB path require Servo HRV3 control.
If Learning axis is full-closed system, outer detection I/F unit must be connected with the same path as
Learning axis.
There is the following restriction with regard to the possible number of unit connecting with the same FSSB
path.

HRV2 16 / 2
HRV3 10 / 2
HRV4 4 / 1
