YASKAWA HV600 Manual page 289

Note:
• To use the N.C. switch to input the fast stop command, set 17 (Fast Stop (N.C.)).
• Refer to
C1-09: Fast Stop Time on page 224
• 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
Setting Value Function
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.
ON : Selects motor 2.
OFF : Selects motor 1.
When you select motor 2, the drive will switch to motor 2 parameters.
Parameter
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, E4-xx [Motor Parameters]
Note:
• When you use 2 motors, the drive applies the protective function set in L1-01 [Motor Overload (oL1) Protection] 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 [Motor Switch
during Run] alarm.
• You must wait 200 ms minimum to input a Run command.
• If you set H1-xx = 16 [Motor 2 Selection] and set different control methods in maximum output frequency to motors 1 and 2, the drive will
apply the lower of the two maximum to the two motors. The upper limit of d1-xx [Frequency Reference] will change. For example, the
upper limit of d1-xx will be 400 when you set these parameters to these values:
–A1-02 = 5 [Control Method Selection = OLV/PM]
–E1-04 = 590 [Maximum Output Frequency = 590 Hz]
–E3-01 = 0 [Motor 2 Control Mode Selection = V/f Control]
–E3-04 = 400 [Motor 2 Maximum Output Frequency = 400 Hz]
• For software version PRG: 01011, when Motor 2 Selection is ON, the drive sets acceleration and deceleration times to 10.0 s.

17: Fast Stop (N.C.)
Setting Value 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:
