The drive generates a warning, 7381 Encoder. The FEN-xx
module will continue to update speed and position data.

The drive trips on fault A7E1 Encoder.
Fault
Initial position / uint16
(Visible when 92.1 Encoder 1 type = Absolute encoder)
Selects the serial link mode with an EnDat or SSI encoder.
Serial link mode92.30
0Single position transfer mode (initial position).Initial position
1Continuous position data transfer mode.Continuous
2Continuous speed and position data transfer mode. This
setting is intended for EnDat 2.2 encoders without sin/cos
signals.
Note: This setting requires an FEN-11 interface revision
H or later.
Continuous speed
and position
50 ms / uint16
(Visible when 92.1 Encoder 1 type = Absolute encoder)
Selects the maximum encoder calculation time for an EnDat
encoder.
Note: This parameter needs to be set only when an EnDat
encoder is used in continuous mode, ie. without incremental
sin/cos signals (supported only as encoder 1). See also
parameter 92.30 Serial link mode.

(Visible when 92.1 Encoder 1 type = Absolute encoder)
Selects the transmission cycle for an SSI encoder.
Note: This parameter needs to be set only when an SSI
encoder is used in continuous mode, ie. without incremental
sin/cos signals (supported only as encoder 1). See also
parameter 92.30 Serial link mode.

2 / uint16
(Visible when 92.1 Encoder 1 type = Absolute encoder)
Defines the length of an SSI message. The length is
defined as the number of clock cycles. The number of
cycles can be calculated by adding 1 to the number of bits
in an SSI message frame.

1 / uint16
(Visible when 92.1 Encoder 1 type = Absolute encoder)
With an SSI encoder, defines the location of the MSB (most
significant bit) of the position data within an SSI message.
