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.9.2 Select the brake resistor cables
Use a shielded cable to the resistor cable.
C.9.3 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 Celsius degrees.
Protect the resistor against contact.
