In the case that the internal dynamic resistor is used in 3.7kW model or less, then do not
use any external braking resistors. When using an external braking resistor instead of
the internal resistor, change the connection of the internal resistor from terminal PB1 to
terminal PR1. (For boosting braking force)
Do not connect an external resistor with a resistance (combined resistance) smaller
than the minimum admissible resistance.
For overload protection, be sure to set the parameters
and
properly.
