Minimum load current
The minimum load current is 20% of the set motor current, but at least the absolute minimum
current specified in the tables below.
The minimum load current differs between the ET 200SP motor starters and the
fail-safe ET 200SP motor starters:
Load current
0.1 … 0.4 A
0.3 … 1 A
0.9 … 3 A
2.8 … 9 A
4 ... 12 A
Motor/ohmic load of motor starter 0.05
0.15
0.18
0.56
0.8
Motor load of fail-safe motor starter 0.05
0.15
0.45
1.4
2
As soon as the minimum current limit is undershot during operation, the fault detection
(residual current detection) picks up.
Disconnection or a warning is triggered depending on the setting of the
"Response to residual current detection" parameter.
Residual current detection cannot be parameterized to "Warn" in the case of
fail-safe motor starters.
