Parameter
C5-xx [Automatic Speed Regulator (ASR)]
E1-xx, E3-xx [V/f Patterns]
E2-xx, E4-xx [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 (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] 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.
• 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 = 2 [Control Method Selection = OLV]
–E1-04 = 590 [Maximum Output Frequency = 590 Hz]
–E3-01 = 3 [Motor 2 Control Mode Selection = CLV]
–E3-04 = 400 [Motor 2 Maximum Output Frequency = 400 Hz]

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:
• 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 772
• 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.
Figure 12.82 shows an example of how fast stop operates.
