If you are purchasing a braking unit from mitsubishi you can find your appropriate resistor by looking at the brake resistors for brake units table.
Mitsubishi inverter brake resistor.
Install the high duty brake resistor fr abr as follows.
Twist the leads of the high duty brake resistor when increas ing their length 2m or more.
When connected to a suitable inverter drive this will reduce the stop time by absorbing energy returning from the load.
Otherwise the brake resistor may excessively overheat due to damage of the brake transistor and such causing a fire.
Returns regeneration energy to the power supply enabling continuous.
240mm x 50mm x 21mm mounting.
Via 4 3mm diameter holes.
The surface temperature of braking resistors can far exceed 100 c for brief periods.
This instruction manual gives handling information and precautions for use of this equipment.
Refer to the instruction manual of the inverter.
The inverter without a built in brake transistor can be connected.
Do not connect a resistor directly to the dc terminals p and n.
The high duty brake resistor cannot be used with a brake unit high power factor converter power return converter built in brake etc.
For use with fr d720s and fr e720s series inverters rated at 1 5kw or 2 2kw.
Mount the brake resistor on an incombustible surface.
Otherwise a brake transistor failure or the like can overheat the brake resistor abnormally causing a fire.
The brake unit the resistor unit and the dischaging resistor must be installed on a nonflammable wall without holes.
Increases the braking capability more than the brake resistor.
The brake resistor may be mounted horizontally or vertically depending on a suitable surface location.
Some drive models come come with a large brake transistor built in you can find their minimum resistance and max braking power in the drives with internal braking transistors table.
Mitsubishi external dynamic braking resistor 60 0 ohms x 120 watts 0 12kw.
This could cause a fire and destroy the inverter.
When the brake resistor is mounted externally to the enclosure housing the inverter install a solid type 1 enclosure at least 8 times the volume size of the brake resistor that incorporates mesh or perforated steel type ventilation.
A high power factor converter whose.
Installing the inverter directly on or near a combustible surface could lead to a fire.
Mitsubishi inverter option catalog 5 6 a700 1 2 3 regeneration unit option is necessary for regeneration.
Use the alarm signal of the brake unit to switch power off.
Increases the braking capability of the inverter which has a built in brake transistor.
Thank you for choosing this mitsubishi inverter option unit.
The inverter without a built in brake transistor can be connected.
When the brake resistor is mounted externally to the enclosure housing the inverter install a solid type 1 enclosure at least 8 times the volume size of the brake resistor that.
