Danger
Please utilise extreme caution when performing work within the compressor. Wear
appropriate PPE
(Personal Protective Equipment)
, follow
lock out-tag out
procedures, and
ensure all safety procedures
.
Check parameter 5.07
High voltage drive : 5.07 = 34 Amps
Low voltage drive : 5.07 = 54 Amps
Yes
“Motor I²t” : motor current (4.01) exceeds value set in parameter 5.07
Should go through similar process if:
High voltage drive: current > 23 Amps
Low voltage drive: current > 45amps

Reset the fault
Start the compressor and check
parameter 4.01
4.01 > 5.07 ?
No
Is incoming voltage within the
tolerances ?
No
High current consumption likely to be due to
abnormal torque requirement –
eg:
-NDE bearing
-Tight airend
-Low coolant level
No
Yes
Bring power supply
within tolerances
Yes
