Description
The drive generates an ENCODER 1/2 CABLE warning. This
is the recommended setting if the maximum pulse frequency
of sine/cosine incremental signals exceeds 100 kHz; at high
frequencies, the signals may attenuate enough to invoke the
function. The maximum pulse frequency can be calculated as
follows:
Max. pulse frequency =
Setting this parameter to 1 forces a reconfiguration of the
FEN-xx interfaces, which is needed for any parameter
changes in groups 90...93 to take effect.
Note: The parameter cannot be changed while the drive is
running.
Reconfiguration done.
Reconfigure. The value will automatically revert to Done.
Absolute encoder configuration. See also section
support on page 31.
Defines the number of sine/cosine wave cycles within one
revolution.
Note: This parameter does not need to be set when EnDat or
SSI encoders are used in continuous mode. See parameter
91.25 SSI mode / 91.30 Endat
Number of sine/cosine wave cycles.
Selects the source for the encoder position (zero position).
Not selected.
Commutation signals.
Serial interface: EnDat encoder.
Serial interface: HIPERFACE encoder.
Serial interface: SSI encoder.
Serial interface: Tamagawa 17/33-bit encoder.
Defines the number of bits used in revolution count (for
multiturn encoders). Used with serial interfaces, i.e. when
parameter 91.02 Abs enc interf
SSI or Tamag. 17/33b.
Number of bits. For example, 4096 revolutions corresponds
to 12 bits.
Defines the number of bits used within one revolution. Used
with serial interfaces, i.e. when parameter
interf setting is EnDat, Hiperface,
Number of bits. For example, 32768 positions per revolution
corresponds to 15 bits.
Enables the encoder zero pulse (if used). Zero pulse can be
used for position latching.
Note: With serial interfaces (i.e. when parameter
enc interf setting is EnDat, Hiperface,
zero pulse must be disabled.
Zero pulse disabled.
Zero pulse enabled.
