4 - 6 Alpha Series servo Amplifier Module (SVM) with FSSB - April 1998 GFK-1546

The ATR for each slave must be set. A slave consists of a servo amplifier and pulse module
connected to the CNC by an optical cable. A 2-axis amplifier has two slaves, and a 3-axis
amplifier has three slaves. Each slave is assigned a number, from 1 to 10, according to its
distance from the CNC.
• For an amplifier, set the value which is one less than the value of parameter No. 1023.
• For a pulse module, set 16 for the first pulse module (closest to the CNC) and 48 for the
second pulse module (farthest from the CNC).
• If there is no slave, set 40.
• For the Electric Gear Box function, the EGB dummy axis, designated in parameter No. 7771,
does not require an amplifier. However, do not set 40. Instead, set the values which is one
smaller than the value of parameter No. 1023 for the EGB axis.
Note
When parameter No. 1902#0=0, these bits are set automatically. When
parameter No. 1902#0=1, these bits must be set manually.
