Appendix
A.1.3 Comparison of Control Circuit Terminal Block
 Spring clamp type terminal block is used for control circuit terminal block of both WJ200 and
A
WJ-C1, and the recommended wire diameter and terminal are the same. For details, refer to
"5.4.2 Recommended Wire Diameter and Wiring Method for Control Circuit Terminals".
■ Comparison of control circuit terminal block arrangement
WJ200
WJ-C1
* Terminals that have been added/changed electrical characteristics/changed functions compared to
WJ200 are outlined in white.
For those whose terminal symbols only have been changed, refer to the following comparison table.
* The following terminals have the same function/electrical specifications, but the terminal symbols have
been changed. Be careful when switching wiring.

By turning ON the safety function
selector switch on the control
board, input terminals 3 and 4 are
switched to the safety function STO
input terminals [GS1] and [GS2].
By turning ON the EDM function
selector switch on the control
board, output terminal 11 is
switched to the EDM output
terminal.

In addition, [P24S] and [CMS] have been added
P24S as dedicated power supply for functional safety.
Refer to "14.1 Using the Safety Function STO
CMS
(Safe Torque Off)" for more information.
In addition to the content shown on the left, in
case EDM function selector switch is ON, the

switch to the status monitor of [ST1] and [ST2].
(Terminal functions assigned to input terminals
3 and 4 are not changed.)

In addition to the content shown on the left, by
inputting an external 24 VDC power supply to

this terminal and the [L] terminal, only the
control board can be started.
