Pitagora 4.0 – Motor Data self-learning procedure

---

1) Switch the lift into INSPECTION mode

2) Motor Parameter check

From the main menu, access the Emulation menu.

Main Menu > Emulation > VVVF Advanced

GEARED motors

Parameters normally pre-set if specified when ordering.

VVVF Fuji parameter	Description	Note
P01 – Motor poles	Enter the number of motor poles
F03 – Maximum speed	Enter the maximum motor speed (RPM)
F04 – Rated Speed	Enter the rated motor speed (Hz)
F05 – Rated Voltage	Enter the rated motor Voltage
P03 – Motor Rated Cur	Enter the rated current intensity of the machine
P02 – Motor Rated Cap	Enter the rated power of the machine
C11 – High speed	Set high speed C11 (value specified on the motor nameplate)	Only with magnetic sensors counting system (FAI / FAS)
C10 – Middle speed	Set inspection/intermediate speed C10	as above
C07 – Creep speed	Set low speed C07 (typically 10% of C11)	as above
L01 – PG select	Set the motor encoder type	Closed loop systems only
L02 – PG resolution	Set the motor encoder resolution (typically 1024)	as above
P04 – Motor Autotuning 3 = Open loop 2 = Closed loop 1= Motors with unknown data	Select 3 Open Loopoptions from the list and press OK on the playpad to confirm.

GEARLESS motors

Parameters normally pre-set if specified when ordering.

Pole tuning is not required if the encoder offset angle is already known.

VVVF Fuji parameter	Description	Note
P01 – Motor poles	Enter the number of motor poles
F03 – Maximum speed	Enter the maximum motor speed (RPM)
F04 – Rated Speed	Enter the rated motor speed (Hz)
F05 – Rated Voltage	Enter the rated motor Voltage
P08 – M-%X	Set the value “10%”	Confirm the proposed value
P07 – M-%R1	Set the value “5%”	as above
P06 – M-No-load Curr.	Set the value “0 Ampere”	as above
P03 – Motor Rated Cur	Enter the rated current intensity of the machine
P02 – Motor Rated Cap	Enter the rated power of the machine
C11 – High speed	Set high speed C11 (value specified on the motor nameplate)	Only with magnetic sensors counting system (FAI / FAS)
C10 – Middle speed	Set inspection/intermediate speed C10	as above
C07 – Creep speed	Set low speed C07 (typically 10% of C11)	as above
L01 – PG select	Set the motor encoder type	Closed loop systems only
L02 – PG resolution	Set the motor encoder resolution (typically 1024)	as above
L03 – P.P. Tuning 4 = Static tuning (depending on the motor type 5 = Dynamic tuning (free from ropes)	Select 4 Static tuningoptions from the list and press OK on the playpad to confirm.

3) Closing of Self-learning phase

Pole tuning troubleshooting

Check that the lift is in temporary operations.

Main Menu > Emulation > Configuration > Temporary operations > YES

Try moving the cabin UP/DOWN manually.
