5-6-4 Brake Mode
Brake function for servo motor and the external mechanical brake if it is used can be set according to
the table below. Set the brake mode as required for Servo off, Emergency Stop and CCW/CW rotation
inhibit functions.

Note!
When the CCW/CW Drive Inhibit occur, the Cn009 has the higher priority than Cn008.
Example:
If Cn008 is set to 0 or 1 which means (no Dynamic Brake).
BUT Cn009= 1 (with Dynamic Brake), then the dynamic brake will be effective( enabled).
5-6-5 Timing Diagram of Mechanical Brake
In applications with vertical loading, if the power is turned off, to prevent the load from falling due to
gravity, a servo motor with electro-mechanical brake can be used.
This servo drive provides a brake output (BI) which can be used for controlling the external brake.
Timing of brake output signal can be set by parameter Cn003 (Output Time for electro-mechanical
Brake).
