P6-21 Brake chopper operating cycle at undertemperature

Setting range: 0.0 – 20.0%

A value > 0 activates the heating function of the inverter.

The brake chopper is thereby active at temperatures below 0 °C (even with low temperature error U-Temp) and heats the connected braking resistor to the set value.

For this, the braking resistor must be installed directly on the heat sink to ensure optimum thermal conductivity.

Please use only the braking resistors provided for this.

Please contact SEW‑EURODRIVE Service, if necessary.

An excessive value can overload the braking resistor.

Use an external thermal protection device for the braking resistor.

When set to "0.0", this function is deactivated.
