
Never use a brake resistor with a resistance below the minimum value specified
for the particular drive. The drive and the internal chopper are not able to handle
the overcurrent caused by the low resistance.

Increase the power of the braking resistor properly in the frequent braking
situation (the frequency usage ratio is more than 10%).
C.8.2 Select the brake resistor cables
Use a shielded cable to the resistor cable.
C.8.3 Place the brake resistor
Install all resistors in a place where they will cool.

The materials near the brake resistor must be non-flammable. The surface
temperature of the resistor is high. Air flowing from the resistor is of hundreds of
degrees Celsius. Protect the resistor against contact.
Installation of the braking resistor:

The 030G/037P and lower models only need external braking resistors.

PB and (+) are the wiring terminals of the braking resistors.
