YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING 161
Figure 2.5 Coast to Stop
Note:
When you enter the Stop command or turn OFF the Run command, the drive ignores the Run command for the time set in L2-03 [Minimum
Baseblock Time]. Do not enter the Run command until the motor comes to a complete stop. Use DC Injection or Speed Search to restart the
motor before it stops.
2 : DC Injection Braking to Stop
When you enter the Stop command or turn OFF the Run command, the drive turns OFF the output for the time set in
L2-03. The drive waits for the minimum baseblock time and then injects the amount of DC current into the motor set
in b2-02 [DC Injection Braking Current] to stop the motor with DC current.
DC Injection Braking stops the motor more quickly than coast to stop.
Note:
If A1-02 = 5, 6, DC Injection Braking to Stop is not available.
Figure 2.6 DC Injection Braking to Stop
The value set in b2-04 and the output frequency when the drive receives the Stop command determine the DC
Injection Braking time. The drive calculates the DC Injection Braking time as in Figure 2.7.
Figure 2.7 DC Injection Braking Time and Output Frequency
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.
