• Terminal 3 function p.30
• Switch sw1 is set to on the input terminal setting for said terminal is automatically changed to no no function assigned when slide switch sw1 is set to on to prevent any duplication of terminal functions even if slide switch sw1 is subsequently returned to off the original function setting for said terminal will not be restored if necessary the original function will have to be re assigned to said terminal p.30
• Switch sw1 is set to off to disable the function p.30
• Signal logic is improper the inverter trips due to emergency stop e37 if this occurs check and correct the wiring and signal logic and then input the reset rs signal only the reset rs signal input from intelligent input terminal 1 can release the inverter from tripping due to emergency stop e37 the inverter cannot be released from the e37 status by any operation from the digital operator p.30
• Of the main circuit elements therefore do not touch any terminals of the inverter or any power lines e g motor cables otherwise electric shock injury or ground fault may result p.30

• Note if intelligent input terminal 3 is left unconnected the cable connected to the terminal is disconnected or the p.30
• Note before operating slide switch sw1 make sure that the input power supply is off p.30
• Function and no other functions can be assigned to these terminals even if other functions have been assigned to these terminals these are automatically disabled and these terminals are used exclusively for the emergency stop function terminal 1 function p.30
• Example if slide switch sw1 is set to on when function 18 rs has been assigned to input terminal 2 by terminal setting c002 example if slide switch sw1 is set to on when function 18 rs has been assigned to input terminal 2 by terminal setting c002 terminal setting c002 is changed to no no function assigned and function 18 rs is assigned to input terminal 1 by terminal setting c001 p.30
• Even if slide switch sw1 is subsequently returned to off terminal 2 function c002 and terminal 1 function c001 will remain as even if slide switch sw1 is subsequently returned to off terminal 2 function c002 and terminal 1 function c001 will remain as no no function assigned and 18 rs respectively p.30
