The materials near the braking resistor must be non flammable.

Braking resistor wiring. More wiring terminal information can be seen. The dynamic braking resistor is connected across the dc bus and will see voltages as high as 800 volts. Case resistors feature a nickel chromium wire helically wound placed inside a ceramic fixture and inserted into a.

The powerohm team is committed to providing the highest value highest quality products at attractive prices. Braking resistor gs2 braking resistor connection. Wiring gage and distance must comply with the connections.

If your braking resistor contains an optional factory wired terminal block then you may connect to the unit with standard 90oc rated wire. Resistor installation and wiring. For todays demanding industries.

The lower the ohmic value of a resistor the faster it can stop the motor and the more heat it generates. Connect the resistor terminals r1 and r2 and the thermal overload switch terminals t1 and. It is important to correctly size a braking resistor.

All resistors must be installed outside the drive module in a place where they can be cooled sufficiently do not block the airflow to other equipment or dissipate hot air into the air inlets of other equipment. The chopper is the dynamic braking circuitry that senses rising dc bus voltage and shunts the excess energy to the dynamic brake resistor. Powerohms type cr resistors are manufactured with quality components for superior performance and increased life expectancy.

Dynamic braking will not provide a holding brake function and is only effective when the motor is rotating. The drive manufacturer normally determines the power rating watts needed to prevent overheating during braking duty. The resistor dissipates regenerated power to keep the bus voltage from exceeding the rated limit of the drive.

1370 dynamic braking resistors catalog numbers 1370 dynamic braking is an optional control function which facilitates motor stopping under fault conditions or in response to a coastdb stop. To compensate this the resistor must be bigger or use a heat sink. Refer to user dynamic braking user manual gs dbump for durapulse resistor connection information.

Connect the grounding lug terminal of both the drive and dynamic braking resistor to ground. Make connections with twisted pair wire.
