 Connection diagram
• The following diagram shows a connection example for emergency drive operation (in the commercial mode).
Emergency drive execution
*1 Be careful of the capacity of the sequence output terminals.
The applied terminals differ by the settings of Pr.190 to Pr.192, and Pr.197 (Output terminal function selection).
Output terminal capacity
Open collector output of inverter
(RUN, FU)
Inverter relay output
(A-C, B-C)
Relay output option
(FR-A8AR)
*2 When connecting a DC power supply, insert a protective diode.
When connecting an AC power supply, use relay output terminals of the inverter or contact output terminals of the relay output option (FR-A8AR).
*3 The applied terminals differ by the settings of Pr.180 to Pr.184 (Input terminal function selection)
*4 The applied terminals differ by the settings of Pr.190 to Pr.192, and Pr.197 (Output terminal function selection).
NOTE
• Be sure to provide a mechanical interlock for MC2 and MC3.
• The emergency drive function is disabled when the Inverter run enable (X10) signal is assigned.
 Emergency drive execution sequence
• When the X84 signal is ON for 3 seconds, the emergency drive is activated.
• The Y65 signal is ON during emergency drive operation.
• "ED" is displayed on the operation panel during emergency drive operation.
• The ALM3 signal is ON when a fault occurs during emergency drive operation.
• For protective functions (faults) valid during emergency drive operation, refer to
