Function
This parameter determines the operating mode of quick acquisition digital inputs.
If MDI8 is used as a frequency input, the option 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 CONTROL MENU or as a PID reference 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 98.
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 respectively (minimum and maximum value
for the frequency input).
