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 the 2 motors are used, a protective function set in L1-01 [Motor Overload Protection Select] is applied to both motors.
• Motors 1 and 2 cannot be switched while during run. Any attempt to switch the motors while they are running will produce a rUn error.
• The wait time for switchover is 500 ms when switching between encoder motors. It is 200 ms for other control methods. After the
motors are switched, input a Run command after waiting over these times.
■
17: Fast Stop (N.C.)
Setting Function
17 Fast Stop (N.C.)
The drive will not restart the motor after fast stop input has been canceled until the following conditions are met.
• The motor is completely stopped.
• The Run command is canceled.
• The fast stop command is canceled.
Note:
• Set 15 (Fast Stop (N.O.)) to input the emergency stop command using the N.O. switch.
• Refer to "C1-09: Fast Stop Time" for details.
NOTICE: Rapid deceleration can trigger an overvoltage fault. Set an appropriate Fast Stop time in C1-09 [Fast Stop Time] to
avoid this uncontrolled motor state and to ensure that the motor stops quickly and safely. The drive output shuts off when faulted
and the motor coasts.
The following time chart shows an example of how fast stop operates.

18: Timer Function Input
Setting Function

When Fast Stop (N.C.) is input while the drive is running, the drive performs ramp to stop in a
deceleration time configured with C1-09 [Fast Stop Time].
