- the encoder assembly position is changed
- the phase sequence of the motor power supply connection is changed
- the encoder incremental signal connection is changed
- the encoder absolute signal connection is changed

- the value of the PAR 2100 Encoder pulses parameter is changed
- the drive is replaced (alternatively, download parameters taken from previous
drive)
There are two different procedures that can be launched by writing two different
parameters:
• PAR 2190 Autophase rotation -> rotation phasing:
this procedure must be performed with the motor free to turn and with no load
applied.
With regard to phasing with the motor stopped, with the Autophase still mode
parameter (PAR 2194) you can select two different methods based on the different
characteristics of synchronous motors on the market.
We recommend using Mode 1 as the rst option. If Mode 1 does not run correctly,
the motor (due to its constructive characteristics) requires a different mode (i.e.,
Mode 2).
• PAR 2192 Autophase still -> static phasing:
this procedure must be performed with the motor still and brake applied.
If an incremental digital encoder is used, you can select different methods for
phasing the motor with the Autophase still run parameter (PAR 2196): via
“Autophase rotation” dedicate command or by Wizard procedure, only at the rst
enabling of the drive ( “First enable” selection) or at each enabling of the drive
(“Each enable” selection).
• PAR 2198 Autophase run type, selection (2) Virtual:
Use this setting when the value in mechanical degrees of the distance of the rotor
pole from the “zero” of the encoder is known. This value must be entered manually
before starting the phasing (contact Gefran’s Customer Service for further informa-
tion).
Rotation phasing
This procedure is based on the possibility of moving the motor, by a maximum
angle of two pole pairs, to nd correct encoder phasing, cross-check the available
encoder and motor data and, if the encoder count direction does not match the
phase sequence of the motor power supply, correct it by automatically modifying
PAR 2130 Encoder direction.
Note! In the case described above, a positive speed reference could generate a rotation in reverse with
respect to that defined as positive for the encoder (usually clockwise), while still ensuring good motor
control.
The encoder direction dened as positive can be stored as the positive reference
direction by inverting two motor power phases and repeating the rotation phasing
procedure.
If the procedure is terminated without any errors, code 0 is shown on the keypad,
otherwise if any differences have been detected that cannot be corrected by the
