7.7.8 Analogue output programmable
In terminal block is available one analogue output programmable (pin: 4 V
out
e 5 0VA). The
parameter Pr188 defines the parameter to monitor. The analogue output scale has a range
from –512 to +512 counts corresponding ±10V. By parameter Pr189 is possible to modify the
scale: the value is the exponent of base 2.
There are three different cases:
Pr188=Pr0, (monitor speed) has in escape +10V when Pr0=+Pr32, while –10V when Pr0=-
Pr32 [with Pr189=0].
Pr188=Pr35, (monitor tourque) has in escape 10V when Pr35 is equal to pick current, if
Pr19=100% [with Pr189=0].
In other cases:
Pr188=Pr…, range in escape ±512 counts as ±10V. Therefore if the parameter to monitor
necessity more counts, is necessary to attribute, to Pr189, a such value to bring
back the scale of reading of the parameter within 512 counts: 2
Pr189
.
7.7.9 Master reference
There are three different type of master reference:
-
Encoder ref.
-
Reference on digital bus via CAN (see “encoder CAN”)
-
Frequency/direction ref.
The type of reference signal must be connected to the relative connector (see par. “
frequency
input/output connection
”).
Each reference has a input counter, that encoder signal is calculated on every edge of A and B
signal. The counter of the motor position increases 4096 imp/revolution. It’s possible to set
the relation between master and slave with multiplicative and divisor factors. The encoder ref.
from IN2/IN3 can be set as frequency/direction input type or as input in quadrature (b42.4 and
b42.5).
