Meaning
Maximum subindex
Peak current
Unit: mA
The adjustable motor current values can be interpreted
as peak values or rms values. The feature bit (8010:54
[} 190]) enables the conversion.
Peak value → Bit 0 = 0 (default with EL7201-001x)
Rms value → Bit 0 = 1 (default with EL7211-001x)
This value is affected by automatic scanning.

The adjustable motor current values can be interpreted
as peak values or rms values. The feature bit (8010:54
[} 190]) enables the conversion.
Peak value → Bit 0 = 0 (default with EL7201-001x)
Rms value → Bit 0 = 1 (default with EL7211-001x)
This value is affected by automatic scanning.
