Absolute encoder configuration
Absolute encoder configuration can be used when parameter 90.01 ENCODER SEL
is set to FEN-11 ABS.
The optional FEN-11 Absolute Encoder interface Module supports the following
absolute encoders:
• Incremental sin/cos encoders with or without zero pulse and with or without
sin/cos commutation signals
• Endat 2.1/2.2 with incremental sin/cos signals (partially without sin/cos
incremental signals*)
• Hiperface encoders with incremental sin/cos signals
• SSI (Synchronous Serial Interface) with incremental sin/cos signals (partially
without sin/cos incremental signals*).
• Tamagawa 17/33-bit digital encoders (the resolution of position data within one
revolution is 17 bits; multiturn data includes a 16-bit revolution count).
See also parameter group 90 ENC MODULE SEL on page 268, and FEN-11 absolute
encoder interface user’s manual (3AFE68784841 [English]).
Note: Configuration data is written into the logic registers of the interface module
once after the power-up. If parameter values are changed, save values into the
permanent memory using parameter 16.05 PARAM SAVE. The new settings will take
effect when the drive is powered up again, or after re-configuration is forced using
parameter 90.06 ENC PAR REFRESH.
Settings
Resolver configuration
Resolver configuration can be used when parameter 90.01 ENCODER SEL is set to
FEN-21 RES.
The optional FEN-21 resolver interface module is compatible with resolvers which are
excited by sinusoidal voltage (to the rotor winding) and which generate sine and
cosine signals proportional to the rotor angle (to stator windings).
Note: Configuration data is written into the logic registers of the adapter once after
the power-up. If parameter values are changed, save values into the permanent
memory by parameter 16.05 PARAM SAVE. The new settings are effective only when
the drive is powered up again, or after re-configuration is forced by parameter 90.06
ENC PAR REFRESH.
