702 YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual
Note:
Set L2-03 to a high value that will not trigger oC [Overcurrent] when the drive uses DC Injection Braking to stop the motor.
3 : Coast to Stop with Timer
Enter the Stop command or turn OFF the Run command and turn OFF drive output and coast the motor to stop.
The drive ignores the Run command until the “Run wait time” t is expired.
To start the drive again, enter the Run command after the “Run wait time” t is expired.
Figure 11.16 Coast to Stop with Timer
The active deceleration time and the output frequency when drive receives the Stop command determine the
length of “Run wait time” t.
Figure 11.17 Run Wait Time and Output Frequency
9 : Stop with Constant Distance
Enter the Stop command or turn OFF the Run command for the drive to always decelerate for the same distance.
The drive uses the active deceleration time and the value set in E1-04 [Maximum Output Frequency] to calculate
stopping distance S1. The drive holds its current speed when stopping from a frequency less than the maximum
speed. When the distance covered is equal to S1 minus S2, the drive ramps to stop in the current deceleration
time. Adjust the stopping precision with d4-12 [Stop Position Gain].
