Error output

(contact output)

(1) This connection diagram shows the example for the sink logic (factory-

set) control circuit. When using the source logic, refer to page 14 for the 
connections.

(2) Use of the 2W1k   is recommended when the frequency setting is 

changed frequently.

(3) Always connect the enclosed DCL at  P1, P. (375,450K)

DCL is prewired in the panel.  P1 terminal is not prepared as terminals. 
(530-900K)

(4) The output terminal can output the error alarm code, and 26 types of 

functions can be independently assigned with Pr. 190 to 195.

(5) The input signal can be changed over with Pr.73.

(6) This is not required when the scale is calibrated with the operation 

panel.

(7) Always ground the inverter unit, DCL and motor.

(8) JOG is assigned. (375-900K)
