– When high–speed HRV current control is to be used, amplifiers for
high–speed HRV current control are required. As the separate
detector interface unit, a separate detector interface unit supporting
servo HRV3 must be used.

For the axes set for high–speed
HRV current control, amplifiers for
high–speed HRV current control
are required.
A unit for servo HRV3 is required.
– When an FSSB line uses high–speed HRV current control,
servo amplifiers for up to four axes can be connected to the
FSSB line, and up to five slaves including a separate detector
interface unit are allowed. When high–speed HRV current
control is used in a system with five or more axes, two FSSB
lines are required, so a TYPE B axis control card is required.
With two FSSB lines, up to eight axes can be controlled.
When an axis control card supporting servo HRV3 is used,
a separate detector interface unit supporting servo HRV3 is
required as the separate detector interface unit even if it is
attached to an FSSB line that does not use high–speed HRV
current control.

When an FSSB line uses high–speed
HRV current control, up to four axes (five
slaves) can be connected to the line.
When an FSSB line does not use high–speed
HRV current control, up to eight axes (10 slaves)
can be connected. The limit on the axis control
card, however, is not exceeded.
