Type System command
Syntax INVERTER_READ(0, station, 0, param_number, param_size, VR)
INVERTER_READ(0, station, 1, alarm_number, VR)

Description INVERTER_READ reads the parameter, speed reference, torque refer-
ence 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/V1000: B1-01=3; B1-02=3.
Make you sure that the Inverter firmware supports the MECHATRO-
LINK-II board.
The command returns -1 if successfully executed and 0 if failed. The
result (if any) is returned in the selected VR.
Arguments • station
The MECHATROLINK-II station number of the Inverter.
• param_number
The number of the parameter to read. See the Inverter manual.
• param_size
The size of the parameter to read, 2 or 4 bytes. Most of the Inverter
parameters are 2 bytes long. See the Inverter manual.
• VR
The address in the VR memory of the CJ1W-MCH72 where the read
information is put. When the function is 4, the result is returned as a
bitwise value. See the table below.
