Parameters 225
FEN-11 TTL Module type: FEN-11 Absolute Encoder Interface. Echo: TTL
encoder input (X41) pulses are echoed to the TTL output.
3
FEN-21 TTL Module type: FEN-21 Resolver Interface. Echo: TTL encoder
input (X51) pulses are echoed to the TTL output.
4
FEN-31 HTL Module type: FEN-31 HTL Encoder Interface. Echo: HTL
encoder input (X82) pulses are echoed to the TTL output.
5
90.05 Enc cable fault Selects the action in case an encoder cable fault is detected
by the FEN-xx encoder interface.
No Cable fault detection inactive. 0
Fault The drive trips on an ENCODER 1/2 CABLE fault. 1
Warning 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:
2
90.10 Enc par refresh 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.
Done Reconfiguration done. 0
Configure Reconfigure. The value will automatically revert to Done.1
91
91 Absol enc conf
Absolute encoder configuration. See also section Encoder
support on page 62.
91.01 Sine cosine nr 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 mode.
0…65535 Number of sine/cosine wave cycles. 1 = 1
91.02 Abs enc interf Selects the source for the encoder position (zero position).
None Not selected. 0
Commut sig Commutation signals. 1
EnDat Serial interface: EnDat encoder. 2
Hiperface Serial interface: HIPERFACE encoder. 3
SSI Serial interface: SSI encoder. 4
Tamag. 17/33b Serial interface: Tamagawa 17/33-bit encoder. 5
91.03 Rev count bits 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 setting is EnDat, Hiperface,
SSI or Tamag. 17/33b.
0…32 Number of bits. For example, 4096 revolutions corresponds
to 12 bits.
