9.6.8 Analogue output programmable
In terminal block is available one analogue output programmable. The parameter Pr188
defines the parameter to monitor. The analogue output scale has a range from –2047 to +2047
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 output +10V when Pr0=+Pr32, while –10V when Pr0=-
Pr32 [with Pr189=0].
Pr188=Pr35, (monitor torque) has in output 10V when Pr35 is equal to pick current, if
Pr19=100% [with Pr189=0].
In other cases:
Pr188=Pr…, range in output ±2047 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 2047 counts: 2
Pr189
.
It’s possible programmable the output to show parameter value coming from
other axis within the same module, as indicated in the following table:
9.6.9 Master reference
There is one type of master reference:
• Encoder 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.
9.6.10 Multiturn absolute encoder phasing on “zero” machine
With a multiturn absolute encoder, initialize the absolute position read at power up on the
motor position by following the procedure below:
- position the mechanical axis on the desired machine point
- disable drive hardware: b41.5=0
- set reference of the operating mode: b40.2=1;
- set desired position in Pr65:64;
- enter command b94.14 to perform the write procedure in the absolute encoder.
- After having entered a multiturn phasing command b94.14, bit b41.6, indicating “phasing
ok” is set to zero. Switch the electronics off and on again to be able to perform other axis
enabling procedures.
