Function
This parameter determines the operating mode of the fast acquisition digital inputs
or the encoders connected to the optional boards
. If MDI8 is used as a frequency
input, the optional
board for encoder B is not required. MDI6 digital input may be
used as a frequency input; if used along with MDI7, it can be used for encoder A
reading.
Reading both encoders A and B can be programmed; parameter C189
defines the
encoder to be used as a reference source (if set as a speed/torque reference
source in the MOTOR CONFIGURATION MENU or as a PID refer
ence source in
the PID CONFIGURATION MENU
) and the encoder to be used as a speed
feedback.
Configuration allowed for quick acquisition digital inputs is shown in Table 111.
If the encoder is used as a reference source, the detected speed value will
be saturated and scaled based on values set in P073 and P074 respectively
(minimum and maximum value for the encoder).
Example:
C189 [A Reference; B Unused], P073 [–1500rpm], P074
[1500rpm] if the encoder
is used as a PID reference, the reference measure is expressed as a percentage
of the max. value [|P073|; |P074|].
If a frequency input is selected, its readout is saturated and scaled based on
parameters P071 and P072 respecti
vely (minimum and maximum value for
the frequency input).
