16i/18i/21i analog servo interface
unit connection material
A-77372EN
6. Setting connector number
Connector number of first interface unit
Connector number of second interface unit
Date type : Byte
Data range : 0 to 3 (in case of analog servo interface unit)
0 to 7 (in case of separate type detector interface unit)
In case of using interface unit, set the value, which subtracts 1 from the connector
number of each axis. Therefore, the number of connector 1 to 8 corresponds to 0 to 7.
Set 0 to the axis without interface unit
It is possible to use any connectors at any axis, but use the connector from the
small number. So, do not use the connector number 4 without using 3.
3) Turning off/on the power to 21i/18i/16i
The description of setting continues to 4) Servo initial setting.
FSSB Setting example in case of using analog servo interface unit
[Example1 : in case of two analog servo axis]
The analog servo interface unit is slave 1. Analog servo amplifiers are considered as
they are connected after the analog servo interface unit. So they are slaves 2 and 3.
