Parameters and firmware blocks
259
90.05 ENC CABLE FAULT FW block: ENCODER (see above)
Selects the action in case an encoder cable fault is detected by the FEN-xx encoder interface.
Notes:
• 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 22.09 SPEED FB FAULT .
(0) No Cable fault detection inactive.
(1) Fault The drive trips on an ENCODER 1/2 CABLE fault.
(2) 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:
90.06 INVERT ENC SIG FW block: None
Rotation direction of encoder signals can be inverted separately without cabling changes.
(0) No Encoder rotation directions are not inverted.
(1) Enc1 Encoder 1 rotation direction is inverted.
(2) Enc2 Encoder 2 rotation direction is inverted.
(3) Both Both encoder 1 and 2 rotation directions are inverted.
90.10 ENC PAR REFRESH FW block: ENCODER (see above)
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.
(0) Done Refreshing done.
(1) Configure Reconfigure. The value will automatically revert to DONE.
