2.5.5 Dynamic Brake (DB) Units
Externally attach a dynamic brake resistor to the SERVOPACK to dissipate regenerative energy when using the
dynamic brake function. The dynamic brake resistor does not need to be installed if the dynamic brake function is
not required.
Use the dynamic brake unit under the following conditions. Contact your Yaskawa representative before using
the unit under conditions more severe than those specified below.
• Allowable load moment of inertia: 5 times the load moment of inertia
• Allowable duty: Less than one DB stop per hour at maximum rotation speed
