NOTICE
OVERHEATING AND DAMAGE TO THE MOTOR
Verify that the motor is properly rated for the maximum current to be applied to the motor.
Consider the duty cycle of the motor and all factors of your application including derating requirements in
determining the current limit.
Failure to follow these instructions can result in equipment damage.
Synchronous motor parameters
Thes e param eters can be acces sed if

is set to
[Sync.

(
SYn
).
In this cas e, the as ynchronous m otor param eters cannot be acces sed.
Once the drive is chos en:
1- Enter the motor nameplate.
2 - Perform the tune.
•
Do an [Auto tuning]
(tUn)
•
Check the state of the synchronous m otor s aliency (See page 113.)
If [Saliency m ot. s tate] (SMOt) dis plays [Med s alient] (MLS) or [High s alient] (HLS)
-
follow the procedure below "
3 - Improve the tune result
"
and
-
follow the the procedure below "
4 - Adjust PHS
"
Or if [Saliency m ot. s tate] (SMOt) dis plays [Low salient] (LLS)
-
follow the the procedure below "
4 - Adjust PHS
"
3 - Improve the tune results.
•
Set [PSI align curr. m ax] (MCr) conform ing to the m axim um m otor current. The m axim um value of [PSI
align curr. m ax] (MC
r
) ) is lim ited by [Current Lim itation] (
CLI
). Without inform ation set [PSI align curr.
m ax] (MC
r
) to [Auto] (
AU
tO
) (s ee page 116)
•
Do a s econd (
tU
n
) after the (MC
r
) m odification.
4 - Adjust PHS.
Adjust [Syn. EMF cons tant] (PHS) to have optim al behavior (See page 116.)
•
Start the m otor at m inim al s table frequency available on the m achine (without load).
•
Check and note the [% error EMF s ync] (
r
dAE
) value. (See page 117)
- If the [% error EMF s ync]
(rdAE)
value is lower than 0%, then [Syn. EMF cons tant] (PHS) m ay be
increased.
- If the [% error EMF s ync] (
r
dAE
) value is upper than 0%, then [Syn. EMF cons tant] (
PHS
) m ay
be reduced.
[% error EMF sync]
(rdAE)
value should be clos ed to 0%.
•
Stop the m otor for m odify PHS in accordance with the value of the
rdAE
(previously noted).
Advices:
The drive m us t be chos en to have enough current according to the need of behavior, but not too m uch, to have
enough accuracy in the current meas urement, es pecially with the high frequency s ignal injection (s ee
