Chapter 5 Metering
Running Time
The Running Time meter parameter logs the amount of time the motor has been
operating. The timer resets to zero and begins counting as each start command is
received.
Table 32 - Metering Parameters Associated with Running Time
Motor Speed
The Motor Speed meter parameter is only valid when using the Linear Speed
Starting or Linear Speed Stopping modes. It provides the estimated motor speed
during either the starting or stopping maneuver. When the controller is not in
these modes, the Motor Speed meter parameter reads zero except when the unit is
at speed. In this case, the parameter displays 100%.
Table 33 - Metering Parameters Associated with Motor Speed
Actual Start Time
The SMC-50 control module logs the start time of the last five motor starts and
stores that information in Parameters 24 through 28. The start time data is stored
in a first-in, first-out method so the record of the last five starts is always
maintained.
Table 34 - Metering Parameters Associated with Actual Start Time
TIP
When the controller is stopped, the parameter displays the length of time
the motor was previously operating.
