3. Wiring
1) Precaution when wiring the signal line
The dynamic brake and braking resistor may generate strong noise,
thus wire separately the signal lines, which are not tolerant to noise.
2) Wiring method and distance
Follow the wiring methods and distances of the dynamic brake,
Braking resistor and inverter as shown on the figure 3.

4. Braking voltage
1) Controlling the braking start voltage
The dynamic brake is related to the braking start voltage.
Refer to the Table 1. When setting the braking start voltage.
Table 1. Braking start voltage for each source voltage

208V
200V
Note: The variance of source voltage is ¡ ¾ 10V.
The voltage-selection switch, 4P DIP SW., is located on the front of the
dynamic brake. Turn on only one of the switch corresponding to desired
braking start voltage, and turn off the rest of them.

5. Operation
1) Check if the required braking characteristic can be obtained.
2) Dynamic brake is operated when the inverter is starting to decelerate
and the BRAKE LED (yellow) is ON at this time.
3) If the FAULT LED is ON, 1) braking resistance is higher than the
rated value, or 2) output wire short occurred, or 3) the error has
occurred in the braking unit.
Check the problem before restarting.
Note: High voltages in the dynamic brake may cause electric shock.
Be sure to keep the cover closed when operating.
