If the drive detects a fault for which you can set the stopping method, apply the appropriate Stopping Method.
Then push (RESET) on the keypad to turn the Run command OFF, or activate the fault reset terminal to reset
the fault.
Note:
The drive ignores the fault reset command when the Run command is active. Remove the Run command before trying to reset a fault.

15: Fast Stop (N.O.)
Setting Value Function
15 Fast Stop (N.O.)
If you cancel the fast stop input, the drive will not restart the motor until you meet these conditions:
• Fully stop the motor
• Cancel the Run command
• Cancel the fast stop command
Note:
• To use the N.C. switch to input the fast stop command, set 17 (Fast Stop (N.C.)).
• For details, refer to C1-09 [Fast Stop Time].
• Set C1-09 [Fast Stop Time] to a correct deceleration time. If the deceleration time is too short, it can cause an overvoltage fault and
failure to stop the motor from coasting.

16 Motor 2 Selection
You can use an external input to switch operation between two induction motors. The drive will save the control
methods, V/f patterns, and motor parameters for the two motors.

OFF : Operate motor 1
When you select motor 2, the drive will switch to motor 2 parameters.

Note:
• When you use 2 motors, the drive applies the protective function set in L1-01 [Motor Overload Protection Select] to motor 1 and motor
2.
• You cannot switch between motors 1 and 2 during run. If you try to switch motors when they are running, it will cause a rUn error.
• You must wait 200 ms minimum to input a Run command.
