LATCH POS 1 FAILURE
(0x7382)
Position latch 1 from encoder 1
or 2 has failed.
Check latch source parameter settings:
. Note that zero pulse is not always
supported. *
Check that appropriate encoder interface 1/2
is activated by parameter
.
Note:
The new setting will only take effect
after parameter
used or after the JCU control unit is powered
up the next time.
* - Zero pulse is supported when TTL input of
encoder interface module is selected (i.e. par.
=
,
,
or
- Zero pulse is supported when absolute
encoder input of encoder interface module is
selected and zero pulse is enabled (i.e.
=
and
and
- Zero pulse is not supported when resolver
input is selected (i.e.
=

LATCH POS 2 FAILURE
(0x7383)
Position latch 2 from encoder 1
or 2 has failed.
See alarm LATCH POS 1 FAILURE.

ENC EMULATION
FAILURE
(0x7384)
Encoder emulation error
If position value used in emulation is
measured by encoder:
- Check that FEN-xx encoder used in
emulation (
)
corresponds to FEN-xx encoder interface 1 or
(and) 2 activated by parameter
activates the position
calculation of the used FEN-xx input).
If position value used in emulation is
determined by drive software:
- Check that FEN-xx encoder used in
emulation (
)
corresponds to FEN-xx encoder interface 1 or
(and) 2 activated by parameter
(because position data used in emulation is
written to FEN-xx during encoder data
request). Encoder interface 2 is
recommended.
Note:
The new setting will only take effect
after parameter
used or after the JCU control unit is powered
up the next time.
