*Encoder phase angle (servo mode only)
With drive software version V01.08.00 onwards, the encoder
phase angles in Pr
3.25
and Pr
21.20
are copied to the
SMARTCARD when using any of the SMARTCARD transfer
methods.
With drive software version V01.05.00 to V01.07.01, the
encoder phase angles in Pr
3.25
and Pr
21.20
are only copied
to the SMARTCARD when using either Pr
0.30
set to Prog (2)
or Pr
xx.00
set to 3yyy.
This is useful when the SMARTCARD is used to back-up the
parameter set of a drive but caution should be used if the
SMARTCARD is used to transfer parameter sets between drives.
Unless the encoder phase angle of the servo motor connected
to the destination drive is known to be the same as the servo
motor connected to the source drive, an autotune should be
performed or the encoder phase angle should be entered
manually into Pr
3.25
(or Pr
21.20
). If the encoder phase angle
is incorrect the drive may lose control of the motor resulting in
an O.SPd or Enc10 trip when the drive is enabled.
With drive software version V01.04.00 and earlier, or when
using software version V01.05.00 to V01.07.01 and Pr
xx.00
set to 4yyy is used, then the encoder phase angles in Pr
3.25
and Pr
21.20
are not copied to the SMARTCARD. Therefore,
Pr
3.25
and Pr
21.20
in the destination would not be changed
during a transfer of this data block from the SMARTCARD.
