12.3 b: Application
Note:
If the drive detects oC [Overcurrent] when it uses DC Injection Braking to stop the motor, set L2-03 to a high value that will not trigger
oC.
3 : Coast to Stop with Timer
When you enter the Stop command or turn OFF the Run command, the drive turns OFF the output and coasts the
motor to stop. The drive ignores the Run command until the "Run wait time t" is expired.
To start the drive again, wait until the the "Run wait time t" is expired then enter the Run command.
The active deceleration time and the output frequency when drive receives the Stop command determine the
length of "Run wait time t".
9 : Stop with Constant Distance
When you enter the Stop command or turn OFF the Run command, the drive always decelerates 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].
