Pr188=Pr35, (monitor torque) has in escape 4,096V when Pr35 is equal to pick current,
if Pr19=100% [with Pr189=0].
In other cases:
Pr188=Pr…, range in escape ±512 counts as ±4,096V. 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:

10.8.9. 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).
