Description
INVERTER_READ
reads the parameter, speed reference, torque reference
or alarm from the Inverter connected to the system via the MECHATROLINK-
II bus.
There are five
INVERTER_READ
functions:
•
0: Reads an Inverter parameter.
•
1: Reads the Inverter alarm.
•
2: Reads the speed reference.
•
3: Reads the torque reference.
•
4: Reads the Inverter inputs.
To use an Inverter via MECHATROLINK-II you must put the command and
the reference via communication option:
•
Inverter MV/V7: N3=3; N4=9
•
Inverter F7/G7: B1-01=3; B1-02=3.
Make you sure that the Inverter firmware supports the MECHATROLINK-II
board.
The command returns 1 if successfully executed and 0 if failed. The result (if
any) is returned in the selected VR.
