6.3 CAUTIONS
CAUTION
Pay attention to the following points when motors with built-in brakes
are used.
1 A built-in brake is used as a holding brake to prevent falling
along an axis at servo off. This brake functions as a brake at an
emergency stop or power failure, but cannot be used to decrease
the stop distance during ordinary deceleration.
2 The brake cannot be used as assistance to stop the motor in the
stopped state with energization of the motor. This causes an
abnormal heat of the motor.
3 Match the timing of brake release (axis release) to the timing of
servo on (motor energization) as much as possible.
Similarly, match the timing of brake start (axis fix) to the timing
of servo off as much as possible.
4 The total length of a model such as the α40i with a built-in brake
is much longer than that of the model with no built-in brake.
Be careful not to apply excessive force to the opposite side of the
mounting flange or to apply excessive acceleration to the entire
motor.
