Note:
When b2-01 ≤ E1-09, the drive will start Zero Speed Control from the frequency set in E1-09.
1 : Coast to Stop
When you enter the Stop command or turn OFF the Run command, the drive turns OFF the output and coasts the
motor to stop.
Load conditions will have an effect on the deceleration rate as the motor coasts to stop (for example, mechanical
loss and inertia).
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 or 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 = 3, 4, 5, 6, or 7, DC Injection Braking to Stop is not available.
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
