Control I/O Remote I/O + Multi-Function Input Monitor - Omron 3G3MV-PDRT2 User Manual

Remote I/O Functions
● Input Data Details
Word Signal name
m+1 Output frequency monitor
(3G3MV/3G3RV/3G3PV/
3G3FV)
m+2 Torque reference monitor
(3G3MV/3G3RV/3G3PV/
3G3FV)
m+3 Output current monitor
(3G3MV/3G3RV/3G3PV/
3G3FV)
Note 1. The data setting units can be changed in parameter n35/o1-03 (frequency reference set-
ting/display unit).
Note 2. The torque reference monitor is valid only if open-loop vector control (sensor-less vector
control) or flux vector control is set.

5-6-2 Control I/O Remote I/O + Multi-function Input Monitor

This remote I/O setting attaches the 8-bit multi-function input monitor data to the control I/O remote
I/O function described in 5-6-1 Control I/O Remote I/O Operation.
The multi-function input monitor allows the ON/OFF status of the Inverter's control input terminals to
be monitored at the Master. For example, if a particular multi-function input terminal is set to "Not
used" in the parameters, a sensor or other input device can be connected to that terminal and the
signal can be used in the PLC's ladder program.
Note The bits in the multi-function input monitor will be turned ON not only when the terminal's sig-
nal is ON, but also when the corresponding bit is turned ON from remote I/O. (The terminal's
ON/OFF status is logically ORed with the status of the bit sent through remote I/O.)
Gives the frequency being output by the Inverter.
• Monitor unit: 0.01 Hz (See note 1.)
Example: Output frequency when the monitor value is 1388 hex:
1388 hex = 5000 decimal × (0.01 Hz) = 50.00 Hz
Gives the torque reference value inside the Inverter (See note 2.)
• Monitor unit: 0.1% (100% is motor rated torque)
Example: Torque reference for monitor value of 1F4 hex:
1F4 hex = 500 decimal × (0.1%) = 50% (relative to
motor rated torque)
Gives the value of the current being output by the Inverter
• 3G3MV Monitoring units:
0.01 A (when the content of n179 is 0027 or higher)
0.1 A (when the content of n179 is 0026 or lower)
• 3G3RV/3G3FV Monitoring units:
0.01 A (for Inverters with maximum motor capacity of 7.5 kW max.)
0.1 A (for Inverters with maximum motor capacity of 11 kW min.)
Example: Output current for 0.4-kW 3G3RV Inverter with monitor
value of C8 hex:
C8 hex = 200 decimal × (0.01 A) = 2.00 A
