b2-04: DC Inject Braking Time at Stop
No.
Name
(Hex.)
b2-04 DC Inject Braking Time at
Stop
(018C)
This function fully stops a motor with a large inertia during deceleration and will not let the inertia continue to rotate
the motor.
Set this parameter to 0.00 to disable the function.
When a longer time is necessary to stop the motor, increase the value.

b2-09: Pre-heat Current 2
No.

■
b2-12: Short Circuit Brake Time @ Start
No.
Name
(Hex.)
b2-12 Short Circuit Brake Time @
Start
(01BA)
This function stops and restarts a coasting PM motor. The drive short circuits all the three motor phases to make
braking torque in the motor.
Set this parameter to 0.00 to disable the function.
Note:
Short circuit Braking will let external forces rotate the PM motor. Use DC Injection Braking to prevent motor rotation from external forces.
■
b2-13: Short Circuit Brake Time @ Stop
No.
Name
(Hex.)
b2-13 Short Circuit Brake Time @
Stop
(01BB)
This function fully stops a PM motor with a large inertia during deceleration and will not let the inertia continue to
rotate the motor.
Short Circuit Braking operates for the time set in b2-13 when output frequency is less than the value set in b2-01 [DC
Injection/Zero SpeedThreshold] or E1-09 [Minimum Output Frequency].
Set this parameter to 0.00 to disable the function.
■
b2-18: Short Circuit Braking Current
No.
Name
(Hex.)
b2-18 Short Circuit Braking
Current
(0177)
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor rated current.
• A1-02 = 5 [OLV/PM]: E5-03 [PM Motor Rated Current (FLA)]
• A1-02 = 8 [EZOLV]: E9-06 [Motor Rated Current (FLA)]
The Short Circuit Braking current cannot be higher than the drive rated current, although you can use b2-18 to set a
higher current level. The maximum rated current is 120%.
