Figure 2.6 DC Injection Braking at Stop Function
Note:
• If the mechanical operation of the holding brake is slow, use DC Injection Braking until the brake is fully closed to prevent rollback.
• If you cannot hold the load with DC Injection Braking when it is stopped in V/f Control and Open Loop Vector Control modes, use Dwell
Function at Stop.
–b6-03 [Dwell Reference at Stop]: Minimum output frequency to 3.0 Hz
When Frequency Detection 2 is OFF, it is less than L4-01 [Speed Agree Detection Level] - L4-02 [Speed Agree Detection Width].
–b6-04 [Dwell Time at Stop] recommended setting: 0.3 s to 0.5 s
–b2-04 [DC Inject Braking Time at Stop] recommended setting: 0.0 s
Torque Compensation (Torque Bias)
You must detect the load and motoring/regeneration on the machine side before you use the function. If there is a
polarity error, shock can increase.
