Parameter b2-01 sets the frequency to start DC Injection Braking at stop. When the output frequency is less than or equal to the value set in b2-01, the drive will inject the quantity of DC current set in b2-02 [DC Injection Braking Current] into the motor for the time set in b2-04 [DC Inject Braking Time at Stop].
Figure 1. DC Injection Braking at Stop
Note:
When b2-01 ≤ E1-09 [Minimum Output Frequency], the drive will start DC Injection Braking from the frequency set in E1-09.

A1-02 = 4 [AOLV] and n4-72 = 0 [Speed Feedback Mode = With Encoder]

A1-02 = 5, 6, 8 [OLV/PM, AOLV/PM, EZOLV]
|
Parameter b2-01 sets the frequency to start Short Circuit Braking at stop. When the output frequency is less than or equal to the value set in b2-01, the drive will do Short Circuit Braking for the time set in b2-13 [Short Circuit Brake Time @ Stop]. When b2-04 > 0.00 s, the drive will complete Short Circuit Braking, then do DC Injection Braking for the time set in b2-04.
Figure 2. Short Circuit Braking at Stop
Note:
When b2-01 ≤ E1-09, the drive will start Short Circuit Braking from the frequency set in E1-09. If b2-01 and E1-09 = 0 Hz, the drive will not do Short Circuit Braking.

Parameter b2-01 sets the frequency to start Zero Speed Control at stop. When the output frequency is less than or equal to the value set in b2-01, the drive will do Zero Speed Control for the time set in b2-04.
Figure 3. Zero Speed Control at Stop
Note:
When b2-01 ≤ E1-09 [Minimum Output Frequency], the drive will start Zero Speed Control from the frequency set in E1-09.
