Motor Tuning
Tuning the drive to specific motor values will optimize motor performance if parameter [Mot cont. mode
sel.] (Pt) (see page 67
) is set to:
z 2 (constant V/Hz with automatic boost),
z 3 (sensorless vector control), or
z 4 (energy savings)
At a minimum, manually set parameters uL
(vL), uLu (vLv), F415, F416, and F417.
Parameters [Slip Compensation] (F401), [Auto Torque Boost] (F402), [Frequency loop gain] (F418) and
[Freq. loop stability] (F419) can be set manually or they can be set automatically using the auto tuning
function, parameter [Auto-tuning drive] (F400).
More precise motor control adjustments can be made with parameters F307, F480, F485, F492, and
F494 – F496.

uLu [Motor Rated Voltage]
According to drive
rating (1)
According to
drive rating (1)
Set parameter uLu (vLv) to the motor’s rated voltage as indicated on the motor nameplate.
ATV212
pppM3X: 50 to 330 V.
ATV212
pppN4: 50 to 660 V
Note: Drive output voltage cannot be set to exceed the input line voltage level.
uL [Motor rated freq.]
25.0 to 200.0 Hz 50.0 Hz
Set parameter uL(vL) to the motor’s rated frequency as indicated on the motor nameplate.
Note: It is possible to set the drive’s various motor control frequencies to 50 Hz by setting [Parameter reset] (tYP) to 1, the
50 Hz reset. For more information, see page 62
.
tHr [Motor thermal prot.]
Motor rated current overload setting 10 to 100% of the
drive’s output cur-
rent rating
100%
Set parameter tHr to the motor’s rated current as indicated on the motor nameplate for the selected operating voltage.
If parameter [Unit value selection] (F701) is set to 1 (see page 120
), parameter tHr will be adjusted in amperes.
If parameter F701 is set to 0, parameter [Motor thermal prot.] (tHr) will be adjusted in percentage. In this case, divide the
motor rated current by the drive rated current (as listed on its nameplate) and set parameter tHr to the resulting percentage.
The setting of parameter [Switch. freq. level] (F300) does not change the drive’s rated current for the sake of this calcu-
lation (see page
85).
F607 [Mot overload time]
Motor overload time 10 to 2400 s 300 s
CAUTION
RISK OF DAMAGE TO THE MOTOR
Check that the motor will withstand this time without overheating
Failure to follow this instruction can result in equipment damage.
Parameter F607 determines how long the drive will support a 150% motor overload before a fault detection occurs.
F415 [Motor rated current]
0.1 to 200.0 A According to
drive rating (1)
Set parameter F415 to the motor rated current in amperes as indicated on the motor’s nameplate.
F416 [Mot no-load current]
Motor no-load current 10.0 to 100.0% According to
drive rating (1)
Set parameter F416 to the ratio of the motor’s no load current to its rated current.
F417 [Motor rated speed]
Motor rated speed 100.0 to 15000 rpm According to
drive rating (1)
Set parameter F417 to the motor rated speed in rpm as indicated on the motor’s nameplate.
