„ Connections
Connect the Regenerative Resister Unit to the SERVOPACK as shown in the following dia-
gram.
7.5.14 Dynamic Brake (DB) Unit
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.
„ Specifications
The following Dynamic Brake Units are required according to the SERVOPACK model.
Use the Dynamic Brake Unit under the following conditions. Contact your Yaskawa repre-
sentative before using the Unit under conditions more severe than those specified below.
Allowable load moment of inertia: 5 times the load moment of inertia
Frequency of Dynamic Brake (DB) application: Less than one DB stop per hour at maxi-
mum rotation speed
