Motor Start Logs
Description
The LTMT main unit records 250 current values measured during the last motor start.
One log can be saved to serve as motor start reference log.
The last motor start log can be saved as reference log by using:
-
The TeSys Tera DTM.
-
A command from a PLC or DCS through the communication network.
The last motor start log and the reference log:
-
Can be displayed with the TeSys Tera DTM.
-
Are available for PLC or DCS through the communication network.
Two read requests of 128 registers are necessary to read the last motor start log, and two read requests of 128 registers are necessary to read the reference log.
