  • Page 176 Appendix C  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%).
