5.7.9 Dynamic braking
This signal is output when the amplifier detects major fault.
This signal is turned on when such a major fault has occurred that the amplifier cannot drive the motor, and is retained until alarm reset
signal is input.
Dynamic braking is a braking type to short-circuit the coils between three phases of a synchronous motor to generate power.
Once the motor is stopped, braking force is not retained.
The output terminal of dynamic braking is +30V DC, 50mA. This cannot directly close a magnetic contactor. Use a general purpose relay or
FUJI SSC (solid state contactor).
