696 YASKAWA SIEPC71061723A YASKAWA AC Drive CR700 Technical Manual
The user can switch between 2 induction motors using an external input, and operate them. The drive saves the
control methods, V/f patterns, motor parameters, and crane sequences for 2 motors and optimizes control of both
motors.
ON : Selects motor 2
OFF : Selects motor 1
Note:
Refer to
Motor Switch Function on page 216 for details.
■ 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 603 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.
Figure 11.54 shows an example of how fast stop operates.
