Precautions for Correct Use
• The brake built into a Servomotor with a brake is a non-excitation brake designed only to hold
the motor in the stop state when the operation is stopped. Accordingly, set an appropriate
time so that the brake is applied after the Servomotor stops.
• If the brake is applied while the Servomotor is rotating, the brake disc will wear abnormally or
sustain damage. This results in a bearing or encoder failure in the Servomotor.
• The workpiece may fall when the brake is released for a vertical axis. Carefully consider the
timing of releasing the brake.
• For STO or an error applicable to Operation B of a method to stop, in some cases, a Servo-
motor power supply becomes OFF before a brake is held. As a result, a workpiece may fall.
Take a caution of the timing when the brake is held. For a method to stop, refer to Shutdown
option code (605B hex), Disable operation option code (605C hex) and Fault reaction
option code (605E hex).
