∗1. Dynamic brakes are built into the following models:
• SERVOPACKs for one axis: CACR-JU028A, CACR-JU036A, CACR-JU014D, and CACR-JU018D
• SERVOPACKs for two axes: CACR-JUM23 , CACR-JUM24 , and CACR-JUM25
If you use any other model, provide your own dynamic brake circuit.
The dynamic brake on the CACR-JU036A or CACR-JU018D does not operate when the control power supply is
turned OFF.
∗2. Do not use an analog monitor signal for system control. Use an analog monitor signal only for adjusting the motor
or obtaining data for maintenance purpose.

Built into some models or
provided externally by the user.
It operates when an alarm
occurs, when the main circuit
power supply turns OFF, when
the servo turns OFF, or when
the control power turns OFF.
The servomotor coasts to a stop
after the dynamic brake.
