Solution
Make sure L1, L2 terminal voltage is
within recommended range
0A1"
Solution
Make sure U,V,W terminal wired
properly
terminal
Increase main power supply voltage
0A2" / "Er 0A4"
Solution
Make sure of analog input wiring
connection
0A3"
Solution
Measure resistance values
between U, V, W terminals, make
sure the values are almost equal. If
not, might be due to damaged motor
or motor winding open circuit.
