Trace Function - Mitsubishi Electric 800 Series Instruction Manual

Trace function

• The operating status of the inverter can be traced and temporarily stored in the RAM in the inverter. The data stored in the
RAM is deleted when the power supply is turned OFF. (The data is retained at inverter reset.)
• Stored data can be monitored by FR Configurator2, and the status of the inverter can be analyzed.

Sampling starts when the value of the analog monitor exceeds
0
the value set at the trigger level (Pr.1037)
Sampling starts when the value of the analog monitor falls
1
below the value set at the trigger level (Pr.1037)
Set the level at which the analog trigger turns ON.
600 to 1400 The trigger level is the value obtained by subtracting 1000 from
the set value.
