2.8 H: Terminal Function Selection
298 YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING
Note:
• To use the N.C. switch to input the fast stop command, set H1-xx = 17 [Fast Stop (N.C.)].
• Refer to C1-09: Fast Stop Time on page 206 for more information.
• Set C1-09 [Fast Stop Time] to a correct deceleration time. If the deceleration time is too short, it can cause an overvoltage fault, which will
not stop the motor from coasting.
■ 16: Motor 2 Selection
Setting Value Function Description
16 Motor 2 Selection
Sets the command for the drive to operate motor 1 or motor 2. Stop the motors before switching.
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 : Operate motor 2
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.
■ 17: Fast Stop (N.C.)
Setting Value Function Description
17 Fast Stop (N.C.)
Sets the command to ramp to stop in the deceleration time set in C1-09 [Fast Stop Time] when the input terminal is ON while the
drive is operating.
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 on page 206 for more information.
• 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.
