Note:
Select the resistor and power of the braking unit according to the data SALICRU provided.
The braking resistor may increase the braking torque of the inverter. The resistor power in the above table is
designed on 100% braking torque and 10% braking usage ratio. If it’s need more braking torque, the braking
resistor can be decreased properly and the power needs to be magnified.
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 Place the brake resistor
Use shielded cables for braking resistor cables.
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.
Only external braking resistor is needed in CV30.
