Abstract

According to one aspect, there is provided a motor drive controller for use in a network of motor drive controllers, the motor drive controller comprising: a sensor configured to detect a status of a network controller controlling operation of the network of motor drive controllers; and a processor configured to enter into a slave operation mode, in which the processor receives operating instructions from the network controller, or a master operation mode, in which the processor provides operating instructions to the network of motor drive controllers, wherein the processor is further configured to receive the status of the network controller from the sensor and select the master operation mode when the network controller is inactive.

Claims

1. A motor drive controller for use in a network of motor drive controllers, the motor drive controller comprising:

a sensor configured to detect a status of a network controller controlling operation of the network of motor drive controllers; and

a processor configured to enter into a slave operation mode, in which the processor receives operating instructions from the network controller, or a master operation mode, in which the processor provides operating instructions to the network of motor drive controllers, wherein the processor is further configured to receive the status of the network controller from the sensor and select the master operation mode when the network controller is inactive.

2. The motor drive controller of claim 1, wherein the operating instructions received from the network controller comprises an indication that the network controller retains control of the operation of the network of motor drive controllers when the network controller is active.

3. The motor drive controller of claim 1, wherein the operating instructions provided to the network of motor drive controllers comprises an indication that the motor drive controller controls the operation of the network of motor drive controllers when the network controller is inactive.

4. The motor drive controller of claim 1, wherein the processor is further configured to communicate with one or more connected motor drives for control of the one or more connected motor drives independent from the network controller.

5. The motor drive controller of claim 4, wherein the communication between the processor and the one or more connected motor drives includes the status of the one or more connected motor drives;

and motor control commands comprising any one or more of the following;

start, stop, forward run and reverse run, cascade start/stop, die-back, power-save, bag gap control, merge and divert.

6. The motor drive controller of claim 1, further comprising

a housing having an upper portion and a lower portion, both having one or more network controller ports to which the sensor is coupled, wherein the sensor and the processor are disposed in the upper portion and wherein the upper portion is detachable from the lower portion.

7. The motor drive controller of claim 6, wherein the housing is designed to allow at least one of the one or more network controller ports to be detachable and wherein the one or more network controller ports comprises a bypass circuit configured to activate to maintain connectivity of the network of motor drive controllers when the one or more network controller ports are detached.

8. The motor drive controller of claim 6, wherein the processor is configurable to select any one or more of the protocols Ethernet/IP, EtherCAT, ProfiBus and ProfiNet to process signals received from the one or more network controller ports.

9. The motor drive controller of claim 6, further comprising

one or more electrical connectors disposed within the upper portion;

and

one or more matching electrical connectors disposed within the lower portion, wherein each of the one or more matching electrical connectors is aligned to receive a respective electrical connector of the one or more electrical connectors;

wherein one or more electrical components disposed within the upper portion, including the sensor and the processor, are connected to one or more of the electrical connectors; and

wherein one or more electrical components disposed within the lower portion are connected to one or more of the matching electrical connectors.

10. The motor drive controller of claim 6, wherein the upper portion further comprises an infrared port, from which the processor is configured to receive operation parameters;

and a wireless transceiver to which the processor is configured to provide operation parameters.

11. The motor drive controller of claim 6, further comprising a plurality of switching devices that are disposed in the upper portion.

12. The motor drive controller of claim 11, wherein the switching devices are distributed within the upper portion.

13. The motor drive controller of claim 11, further comprising a thermal conductive reservoir disposed within the upper portion, within which the switching devices are immersed.

14. The motor drive controller of claim 6, further comprising an internal fan that is disposed within the upper portion.

15. The motor drive controller of claim 14, wherein the internal fan is configured to activate when the temperature within the housing exceeds a predefined temperature.

16. The motor drive controller of claim 6, wherein an exterior of the upper portion is provided with a heat sink.

17. The motor drive controller of claim 16, wherein the heat sink is provided with an exterior fan.

18. The motor drive controller of claim 17, wherein the exterior fan is detachable from the heat sink.

19. The motor drive controller of claim 1, wherein the processor is configured to process the received operating instructions and provide an operation status, wherein both are compliant with any one or more of the protocols Ethernet/IP, EtherCAT, ProfiBus and ProfiNet.

20. The motor drive controller of claim 1, further comprising one or more memory modules, wherein each of the memory modules is configured to store unique parameters associated with an assigned function.

21. The motor drive controller of claim 20, wherein the one or more memory modules comprises
