Overview
Three quick acquisition digital inputs are available in the Sinus Penta control board:
MDI6/ECHA/FINA;
MDI7/ECHB;
MDI8/FINB.
These inputs can be used as encoder reading (encoder A) or as frequency inputs. In addition, if
ES836
or
ES913
option
board is used (see the Sinus Penta’s
Installation Instructions
manual), an additional encoder reading (encoder B) is
allowed.
NOTE
If
MDI6
and
MDI7
are used for encoder reading, only Push–Pull encoders can be used.
NOTE
For the reversal of the encoder speed measure, properly set up parameter
C199
.

Encoder reading
:
Digital inputs
MDI6
and
MDI7
are used for reading the two channels of a 24V push–pull encoder powered directly by
the Sinus Penta control board (see the Sinus Penta’s
Installation Instructions Manual
).
No function can be programmed for
MDI6
and
MDI7
; if you attempt to program
MDI6
and
MDI7,
alarm
A082
Illegal
Encoder Configuration will trip when
ENABLE
closes.
Reading a Frequency Input
:
Digital inputs
MDI6
or
MDI8
can be used.
If
MDI6
is programmed as a frequency input (
FINA
) with
C189
, no other function can be programmed; otherwise,
alarm
A100
MDI6 Illegal Configuration trips when
ENABLE
closes.
If
MDI8
is programmed as a frequency input (
FINB
) with
C189
, no other function can be allocated to MDI8, and
ES836
or
ES913
option board must not be applied to the power drive, otherwise, alarm
A101
MDI8 Illegal Configuration trips
when
ENABLE
closes.
Reading a Frequency Input and an Encoder
:
MDI6
and
MDI7
are used to read the push–pull encoder, and
MDI8
is used to read the frequency input. The following
alarms may trip:
A082
Illegal Encoder Configuration, if additional functions are allocated to
MDI6
or
MDI7
;
A101 MDI8
Illegal Configuration, if additional functions are allocated to
MDI8
or if the power drive detects the
presence of
ES836
or or
ES913
option board.
