BONFIGLIOLI ACTIVE Manual page 31

In the state word, the current actual value is reported via the bits 12 ... 14 = IW1 ...
IW3. Other settings than those above result in the actual frequency as the content of
PZD2 actual value (matching the setting Bit 12 ... 14 = 0, standard).
On the basis of the property of the data exchange between master and slave via the
DATA_EXCHANGE service, there must be an evaluation in the state word on the mas-
ter's side of the actual value available in PZD2. In DATA_EXCHANGE, the output data
of the master are written and the input data read in one cycle. The input data are
calculated in the previous cycle and temporarily stored in buffers. From these buffers,
they are then read in the DATA_EXCHANGE. This is why at least one cycle is neces-
sary in order to switch the actual values over on the device side.
Note:
Current scaling:
The possible range = ±200 % = +32768 to -32768 = 0x8000 to 0x7FFF
For the standardization the data set change-over capable parameter
371 is used as a reference value.

The displayed "active current" or "torque-forming current" is a function of
the control system in question. In field-orientation, the torque-forming
current is displayed, in applications with a v/f characteristic control, the
active current, which is also a measure for the torque.
The abs. current (r.m.s. current) is always positive. Active current or
torque-forming current have a sign in front.
Positive currents = motor
Negative currents = generator operation.
