Note
:
Select the resistor and power of the braking unit according to the data provided by our company.
The braking 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 braking resistor can decrease properly and the power needs to be magnified.
When using the external braking units, please see the instructions of the energy braking units to set
the voltage degree of the braking unit. Incorrect voltage degree may affect the normal running of the
VFD.
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%).
D.8.2 Selecting the brake resistor cables
Braking resistor cables should be shielded cables.
D.8.3 Placing the brake resistor
Install all resistors in a place with enough ventilation.
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.
Installation of the braking resistor:
The VFDs of 220V (
≤15kW) and 460V (G-type≤30kW, P-type≤37kW) only
need external braking resistors.
PB and (+) are the wiring terminals of the braking resistors.
