Dynamic Braking; Address Error (Control Output Signal) - Fuji Electric Faldic-a RYS-R Series User Manual

5.7.6 Dynamic braking

This signal is turned on when the amplifier detects major fault.
Dynamic braking (Control output signal)
■ Function
This signal is turned on when 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 generate power, by short-circuitting the three-phase winding of a synchronous motor.
Once the motor is stopped, braking force is not retained.
The output terminal of dynamic braking is +30 [V] DC, 50 [mA]. This cannot directly close a magnetic contactor. Use a general-purpose relay
or Fuji's SSC (solid state contactor).
■ Parameter setting
To allocate the dynamic braking signal to the control output terminal, set (15) to the system para.

5.7.7 Address error
Address error of station number can be checked.

Address error (Control output signal)

■ Function
This signal turns on, when a station number at auto start [START] and manual forward command [FWD] address error shown below is
detected.
1) Data other than specified code (BCD or binary) is input.
2) Data other than setting range is input.
This signal turns off, when an auto start is executed at a correct address.
Even if an address error turned on, motor shaft is not stop.
The address can be changed between binary code and BCD code by system para. 98 setting.
