Terminal Block Wiring Procedure
■
Connector-type Terminal Blocks are used for Servo Drivers of 1.5 W or less (except for the R88D-
WN20H-ML2 to R88D-WN30H-ML2). The procedure for wiring these Terminal Blocks is explained
below.
Connector-type Terminal Block
1.Remove the Terminal Block from the Servo Driver.
!Caution
