Note:
Select the resistor and power of the brake unit according to the data our company provided.
The brake resistor may increase the braking torque of the VFD. The resistor power in the
above table is designed on 100% braking torque and 10% braking usage ratio. If the users
need more braking torque, the brake resistor can decrease 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 brake resistor properly in the frequent braking
situation (the frequency usage ratio is more than 10%).
C.7.2 Placing the brake resistor
Use shielded cables for brake 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 degrees Celsius. Protect the resistor against contact.
