Motor History - TeSys Tera Motor Management System

Maximum Start Counter

The LTMT main unit counts the number of motor starts within a given period of time. The number of motor starts is used by the function Maximum Number of Starts.

Maximum Start Inhibit Time

The LTMT main unit tracks the maximum start inhibit time. The maximum start inhibit time is defined by the function Maximum Number of Starts.

Motor Starting Peak Current

The LTMT main unit tracks the maximum current drawn by the motor during the start time. When the motor goes to Start state, the controller starts recording the starting peak current. When the motor goes to Run or Stop state, the controller stops recording the starting peak current.

Motor Starting Time

The LTMT main unit records the time when the motor goes to Start state. The controller stops recording the time when the motor goes to Run or Stop state.

Total Run Hour

The LTMT main unit records the total run hour from the factory reset or Reset total run hour command.

Last Run Hour

The LTMT main unit measures the number of hours the motor has run from the time it has last been started.

Number of Starts

The LTMT main unit counts the total number of times the motor has started.

The number of starts is reset to 0 by:

Return to default values command.
Reset number of starts command.

Number of Stops

The LTMT main unit counts the total number of times the motor has stopped.

The number of stops is reset to 0 by:

Return to default values command.
Reset number of stops command.

Motor Stop Cause

The LTMT main unit counts the total number of times the motor has stopped.

The number of stops is reset to 0 by:

Return to default values command.
Reset number of stops command.
