5.4.1 Voltage at low frequencies (U/f- curve)
Following parameters need to be set for U/f setting. For listed motors, values of these parameters are
stored into the inverter memory, but they can also be set manually or by Autotuning. The manual setting
procedure is as follows:
5.4.1.1 Starting values

# If several motors are connected in parallel, the correct value of R
S
is the resistance of one motor
divided by the number of motors. The correct value of I
N
and I
0
are the value of one motor multiplied
by the number of motors
5.4.1.2 Midpoint voltage adjustment
- Check that there is no load on the crane.
- Set minimum speed for both directions (P1.1.4) to value f
mid
.
- Drive at maximum speed and check the motor current from parameter V2.5.
- Drive at minimum speed. Motor current should be approximately average of measured maximum speed current
and the I
N
.
- Adjust value of parameter U
mid
(P1.2.5.2) until current at minimum speed (= f
mid
) is within desired range.
5.4.1.3 Zero frequency voltage adjustment
- Set minimum speed for both directions (P1.1.4) to value 0.5 * f
mid
.
- Drive at minimum speed. Motor current should be approximately average of measured maximum speed current
and the I
N
.
- Adjust value of parameter U
f0
(P1.2.5.1) till current at minimum speed (=0.5 * f
mid
)
is within desired range
5.4.1.4 Test run
- Set minimum speed for both directions (P1.1.4) to desired minimum speed.
- Drive at minimum speed with nominal load to both directions.
- If motor is not driving at minimum speed, increase values of parameters U
f0
and U
mid
, then continue from
Midpoint voltage adjustment.
# If the main girder is new, it might be necessary to drive trolley several times with no load from end
to end, before beginning of u/f-curve tuning.
