Abstract

A system including a drive portion, and an external computing device in communication with the drive portion, wherein the external computing device is configured to receive operational data from the drive portion, determine operational parameters based at least in part on the operational data, determine whether the operational parameters are valid, and automatically transmit commands to the drive portion if the operational parameters are valid.

First claim

What is claimed is:

1. A system comprising:
drive portion; and
an external computing device in communication with the drive portion;
wherein the external computing device is configured to:
receive first operational data from the drive portion executing a first pre-defined sequence and second operational data from the drive portion executing a second pre-defined sequence,
determine drive parameters based at least in part on the first operational data;
determine whether the determined drive parameters are valid by performing a simulation of the second pre-defined sequence using the determined drive parameters; and
automatically transmit commands to the drive portion if the determined drive parameters are valid.

2. The system of claim 1 , further comprising a motor and a load in communication with the drive portion.

3. The system of claim 2 , wherein the operational data comprises at least one of motor values and load values.

4. The system of claim 3 , wherein the motor values are chosen from a group consisting of motor voltage constant, motor torque constant, motor resistance, motor inductance, motor inertia, and total inertia.

5. The system of claim 3 , wherein the load values are chosen from a group consisting of control line, inductance, line impedance, frequency, voltage, current, and resistance.

6. The system of claim 3 , wherein the commands comprise at least one of motor control parameters and load parameters.

7. The system of claim 1 , wherein the operational data is received and the commands are transmitted continuously.

8. The system of claim 1 , wherein the data is received and the commands are transmitted at predetermined intervals.

9. The system of claim 1 , wherein the system comprises an elevator system.

10. A method of maintaining the operation of an system, the system comprising a drive portion in communication with an external computing device, a motor, and a load, the method comprising the steps of:
transmitting first operational data and second operational data from the drive portion to the external computing device following executing a respective first pre-defined sequence and second pre-defined sequence;
operating the external computing device to determine drive parameters based at least in part on the first operational data;
operating the external computing device to validate the determined drive parameters by performing a simulation of the second pre-defined sequence using the determined drive parameters; and
operating the external computing device to transmit commands to the drive portion if the determined drive parameters are valid.

11. The method of claim 10 , further comprising:
operating the external computing device to generate a fault status and transmit the fault status to the drive portion.

12. The method of claim 10 , wherein the operational data comprises at least one of motor values and load values.

13. The method of claim 12 , wherein the motor values are chosen from a group consisting of control line, inductance, line impedance, frequency, voltage, current, and resistance.

14. The method of claim 12 , wherein the load values are chosen from a group consisting of control line, inductance, line impedance, frequency, voltage, current, and resistance.

15. The method of claim 12 , wherein the commands comprise at least one of motor control parameters and load parameters.

16. The method of claim 10 , wherein the operational data and the commands are transmitted continuously.

17. The method of claim 10 , wherein the operational data and the commands are transmitted at predetermined intervals.
