B2: Dc Injection Braking And Short Circuit Braking - YASKAWA HV600 Manual

Note:
Set this parameter to 0.0 s to disable this function.
When b1-40 > 0.0 s, the drive will coast-to-stop when you remove the Run command and decelerate for the time set
in b1-40. Refer to

b2: DC Injection Braking and Short Circuit Braking

b2 parameters set the DC Injection Braking and Short Circuit Braking functions.
• DC Injection Braking: A braking method that injects DC current into the motor windings. This function should not
be used too frequently, because it generates a fair amount of heat in the motor.
• Short Circuit Braking: A braking method for PM motors.
■
b2-01: DC Injection/Zero SpeedThreshold
No.
Name
(Hex.)
b2-01 DC Injection/Zero
SpeedThreshold
(0189)
Note:
This parameter is available when b1-03 = 0 [Stopping Method Selection = Ramp to Stop].
When the control method selected in A1-02 [Control Method Selection] changes, the b2-01 function changes.
