272 Parameters
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
90.04 ENC CABLE FAULT
Selects the action in case an encoder cable fault is
detected by the FEN-xx encoder interface.
Notes:
At the time of printing, this functionality is only
available with the absolute encoder input of the FEN-
11 based on sine/cosine incremental signals, and
with the HTL input of the FEN-31.
When the encoder input is used for speed feedback
(see 22.01 SPEED FB SEL), this parameter may be
overridden by parameter 22.03 SPEED FB FAULT.
Fault/
UINT32
No
Cable fault detection inactive.
0
Fault
The drive trips on an ENCODER CABLE fault.
1
Warning
The drive generates an ENCODER 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
90.05 INVERT ENC SIG
Defines the encoder signal inversion. No/ enum
No No encoder signal inversion. 0
Enc Encoder signal inverted, that is encoder rotation
direction is changed.
1
90.06 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: This parameter cannot be changed while the
drive is running.
Done/
UINT32
Done Refreshing done. 0
Configure Reconfigure. The value will automatically revert to
DONE.
