BONFIGLIOLI Active Cube Applications Manual

5.1.2.1 Start
Upon first startup after return of mains power, the orientation of the machine is unknown, when a
speed sensor is used. The orientation will only be clear once the reference pulse has been detected.
In order to enable field-oriented operation of a PMSM with speed sensor, the flux direction must either
be known upon first startup after return of mains power or determined by means of the search run
(
Operation Mode Search Run 645). When the reference pulse has been detected, the field orientation
is performed with the detected mechanical position considering of the resolver O
ffset 382.
Before the pulse detection the operation is carried out without encoder.
5.1.2.2 Speed sensor configuration
This software only supports operation with Speed Sensor 2 because Speed Sensor 1 has a lower input
bandwidth. In addition it`s possible to use the PMSM with a simple reference pulse sensor operate.
This pulse can be evaluated via digital input S6IND of the basic unit.
• Set
Operation Mode Speed Sensor 2 493 to “1004 - Quadruple Evaluation w. Ref.-Pulse” or “1104
- Quad. Evaluation inv. w. Ref.-Pulse”.

Quadruple Evaluation
Two-channel speed sensor with recognition of direc-
tion of rotation via track signals A and B; four signal
edges are evaluated per division mark.

-
Quadruple Evaluation inverted
Like Operation Mode 4. The actual speed value is in-
verted (alternatively to the exchange of the track sig-
nals).

Quadruple Evaluation w. Ref.-
Pulse
Two-channel speed sensor with recognition of direc-
tion of rotation via track signals A and B; four signal
edges are evaluated per division mark. The reference
impulse is used for speed sensor monitoring.
1104
-
Quad. Evaluation inv. w. Ref.-
Pulse
Like Operation Mode 1004. The actual speed value is
inverted (alternatively to the exchange of the track
signals).
For speed sensor configuration, also refer to the documentation of the extension module
used.
5.1.2.3 Determination of the flux direction at startup
The flux direction of the machine is determined automatically in the following cases:
− when machine is restarted
− if machine was distorted.
− if power supply of the frequency inverter was interrupted.
