SIMATIC – ET 200pro motor starter
GWA 4NEB 950 5661-02 DS 04
Fault type Meaning / cause
• Thermal motor model
overload
• I - Upper current limit
e
exceeded
• I lower current limit
e
undershot
• Internal error / device
error
• Switching element
defective
• Asymmetry
• Motor blocking
• Residual current
detected
• or in conjunction with
another error type
from this table
• Input tripping
• Input tripping – end
position
• Thermal motor model
has a load > 178%.
Tripping takes place
as device protection
with parameter "Ther-
mal motor model"
= warning.
• Supply voltage for
switching element
missing
Remedy
• Let motor cool down
• Check current consumption of
the motor
• Check set current limits
Switch the supply voltage 1L+ off /
on; if error still present, replace
motor starter.
Check phases L1 to L3.
Remove blocking.
Check main power lines L1 to L3
for interruption.
Remove external error (e.g. move
out of end position)
Check system configuration
Check 2L+
