- How to read the motor's current draw by an ESCON?
The motor current is NOT(!) identical with the current reported by the power supply of the motor controller. The current display of the power supply or measurements with a multimeter are therefore misleading with regard to the motor current.
The motor control is a so-called power converter, i.e. the current and voltage at the motor varies permanently and only the power output from the power supply (= current x voltage) and the power output to the motor correspond (if losses are neglected). More detailed information on this topic can be found in the following linked Support Center document:
ESCON Studio's "Data Recorder":
You can easily record the motor current by ESCON Studio's "Data Recorder".
Select "Actual Current Averaged" by one of the recorder's channels:
If you want to share any recordings with maxon's support team, please right-click in the stopped graphics and select "Export Recorded Data". Select the *.zip file format then which will hold a screenshot plus a data file. Attach this *.zip file to your support request then. Do not(!) just provide a screenshot. Screenshots are not sufficient for any in-depth analysis.
ESCON Studio's "Controller Monitor":
ESCON Studio's "Controller Monitor" also displays the motor current:
ESCON's analog output:
One of the ESCON's analog outputs can be configured to output a voltage corresponding to the motor current:
The scaling of the output voltage (corresponding to the motor current) can be configured:
Always read the "Actual Current Averaged" which is a filtered value. The "Actual Current" has a lot of noise due to current measurement principle.
