11.8 H: Terminal Functions
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.
ON : Selects motor 2
OFF : Selects motor 1
When you select motor 2, the drive will switch to motor 2 parameters.
Parameters
C1-xx [Accel & Decel Time]
C3-xx [Slip Compensation]
C4-xx [Torque Compensation]
C5-xx [Automatic Speed
Regulator (ASR)]
E1-xx, E3-xx [V/f Patterns]
E2-xx, E-4xx [Motor
Parameters]
F1-xx [Number of PG pulses per
Revolution]
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.
• After you switch between encoder motors, you must wait 500 ms minimum to input a Run command. You must wait 200 ms minimum
for other control methods.

17: Fast Stop (N.C.)
Setting Function
17 Fast Stop (N.C.)
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.O. switch to input the fast stop command, set 15 (Fast Stop (N.O.)).
• Refer to "C1-09: Fast Stop Time" for more information.
NOTICE: Fast deceleration can trigger an overvoltage fault. To prevent and uncontrolled motor and to make sure that the motor
stops quickly and safely, set an applicable Fast Stop time in C1-09 [Fast Stop Time]. When there is a fault, the drive output will
turn off and the motor will coast to stop.
Figure 11.84 shows an example of how fast stop operates.
