Our company is engaged in offering a huge gamut of Multi Panels- MM44X.
For several drive applicatins, the motor can go into the regenerative mode (braking mode) for certain operating states.Application Areas:
- Traversing drives
- Conveyor belts, where the load on the belt moves the belt downwards
- Dynamic traversing drives
- Generally - drives with high moments of inertia, if the speed setpoint must be quickly reduced or the load braked.
When the motor is in the regenerative mode, the braking energy of the motor is fed back into the drive converter DC link via the inverter. This means that the DC link voltage increases. If a braking chopper and braking resistor are used, from a specific value of the DC link voltage, the braking energy is pulsed into the braking resistor.
This therefore limits the DC link voltage.
- For MM440, drive units, Sizes A to F have an integrated braking chopper.
- For braking operation, only an external braking resistor has to be connected to terminals B+/DC+ and B-.
- Drive units, Sizes FX and GX do not have an integrated braking chopper.
- Braking operation can only be implemented using an external braking module and an external braking resistor.
- Components from the MASTER-DRIVES range are used to implement this function.
- The engineering and dimensioning of braking modules and braking resistors for MM440 in the power range from 90 to 200kW (CT) will be discussed in the following. It is assumed that the braking module is only connected to a single drive inverter and there is no DC link coupling between several drive inverters.
