2-3-9 Wiring for Emergency Shutoff Function
Precautions for Correct UsePrecautions for Correct Use
• Although this function stops switching of the main element, the circuit is not electrically shut
off. While the power supply is ON, do not touch the inverter terminals and power cable (e.g.
motor cable). Doing so may result in electric shock, injury, or ground fault.
• Before operating slide switch SW1, make sure that the input power supply is OFF.
• If multi-function input terminal S3 is not connected or disconnected, or if the signal logic does
not match, the inverter activates an emergency shutoff trip (E37.*). After checking the cable
connection and the signal logic, input the reset signal (RS).
Note that emergency shutoff trip (E37.*) can be reset only by the reset signal (RS) via
multi-function input terminal S1 and cannot be reset with the Digital Operator.
The slide switch SW1 setting and the status of the multi-function input terminals S1 and S3 are shown
below.
*1 When the Multi-function Input S1 Selection (C001) is set to 18 (RS), C011 is fixed to 00 (NO).
*2 When the Multi-function Input S3 Selection (C003) is set to 64 (EMR), C013 is fixed to 01 (NC).
*3 If the switch SW1 is turned ON with a Multi-function Input terminal other than S1 and S3 set to 18 (RS), the
function to prevent duplicated allocation is activated and automatically changes this Input Selection setting to
no (No allocation). If this occurs, just turning the switch SW1 back to OFF does not restore the previous setting.
Re-allocate the terminal function.
Example: When the Multi-function Input S2 Selection (C002) is allocated to 18 (RS), if the switch SW1 is
turned ON, the C002 setting is changed to no (No allocation), and the Multi-function Input S1
Selection (C001) is allocated to 18 (RS).
Then, even if the switch SW1 is turned back to OFF, the Multi-function Input S2 Selection (C002)
setting is no (No allocation) and the Multi-function Input S1 Selection (C001) is 18 (RS).
*4 Multi-function Input Selection parameters cannot be set to 64 (EMR) via the Digital Operator. This function is
allocated automatically when the slide switch SW1 is turned ON.
*5 Once the slide switch SW1 is turned ON, turning OFF SW1 does not restore the previous allocations for the
multi-function input terminal S1/S3. Allocate the terminal function again.
