NOTE
Requirements for performing HIGH SPEED HRV control
If HIGH SPEED HRV control is to be used, the system must satisfy the following
requirements, such as the required number of slaves, type, and connection
method:
1 If five slaves (amplifiers for four axes, and one Separate Detector I/F Unit) are
connected to a single FSSB and used with HIGH SPEED HRV control, all five
of these slaves must support HIGH SPEED HRV control. In addition, the
Separate Detector I/F Unit must be the fifth slave. If these requirements are
not satisfied, and an attempt is made to set up HIGH SPEED HRV control for
use, alarm SV0456, "ILLEGAL CURRENT LOOP," is issued.
2 The connection of the slaves must satisfy the requirements shown in the
examples below. If these requirements are not satisfied, and an attempt is
made to set up HIGH SPEED HRV control for use, alarm SV0456, "ILLEGAL
CURRENT LOOP," is issued.
<Valid example 1 with FSSB and FSSB2>
SSB1 - AMP - AMP - AMP - PM - PM
SSB2 - AMP - AMP - AMP - AMP
<Valid example 2 with FSSB and FSSB2>
SSB1 - PM - AMP - AMP
SSB2 - AMP - AMP - AMP - AMP - PM
<Valid example 3 with FSSB and FSSB2>
SSB1 - AMP - AMP - AMP - AMP - PM
SSB2 - AMP - AMP - AMP - AMP - PM
<Invalid example 1 with FSSB and FSSB2>
SSB1 - AMP - AMP - AMP - PM - PM
SSB2 - AMP - AMP - AMP - AMP - AMP
<Invalid example 2 with FSSB and FSSB2>
SSB1 - PM - AMP - AMP - AMP - AMP
FSSB2 - PM - AMP - AMP - AMP – AMP
<Valid example with FSSB and Invalid example FSSB2>
SSB1 - AMP - AMP - AMP - AMP - PM
FSSB2 - amp - amp
where
AMP : Servo amplifier adapted to high-speed HRV.
PM : Separate detector interface unit adapted to high-speed HRV.
AMP : Servo amplifier which is not adapted to high-speed HRV.
