DC Brake Current Level 

Unit: 1

 

Settings 

d0 to d30% 

Factory Setting: d0

 

This parameter determines the level of DC Brake Voltage Level output to the motor during 

start-up and stopping.  When setting DC Brake Voltage, the Maximum Output Voltage (Pr.1-

02) is regarded as 100%. It is recommended to start with a low DC Brake Voltage Level and 

then increase until proper holding torque has been attained. 

 

DC Brake Time during Start-up 

Unit: 0.1

 

Settings 

d0.0 to d60.0 sec 

Factory Setting: d0.0

 

This parameter determines the duration of time that the DC Brake Current will be applied to 

the motor during the AC drive start-up.  

 

 

DC Brake Time during Stopping 

Unit: 0.1

 

Settings 

d0.0 to d60.0 sec 

Factory Setting: d0.0

 

This parameter determines the duration of time that the DC brake voltage will be applied to 

the motor during stopping.  If stopping with DC Brake is desired, then Pr.2-02 must be set to 

RAMP stop (d0).

 

 

Start-Point for DC Brake 

Unit: 0.1

 

Settings 

d0.0 to d400Hz 

Factory Setting: d0.0

 

This parameter determines the frequency when DC Brake will begin during deceleration.
