 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 inverters below30kW (including 30kW) only needs external braking
resistors.
 PB and（+）are the wiring terminals of the braking resistors.
