nected
to the EC Controller (terminals "L" and "N"
for 230 V models and terminals "L1", "L2" and
"L3" for 3 x 400 V and 3 x 230 V models).
Lacking operating signal

EC Controller makes
more noise than is ac-
ceptable
Switching frequency too
low
Raise switching frequency.
Holding Registers; address 10: SwitchMode; 0,
1, 2;
0 = Auto, 1 = 4 kHz, 2 = 8 kHz;
Raising the switching frequency increases ener-
gy
loss within the motor. The motor therefore be-
comes
less efficient and less economic to run.
EC Controller cuts out
