14.40 Power Consumption Computation
As the figure below illustrates the flow of the power consumption monitor process. The items (1) to (15) in this figure
correspond to the items given in the previous page.
<<Set by MTB>>
Ladder, APLC
(PLC)
R register (PLC -> NC)
(5) Drive system's fixed consumption
correction
(7) Consumption of devices other
than drive system
Y device (PLC -> NC)
- Clear consumption accumulation 1
to 4
- Enable consumption accumulation 1
to 4
X device (NC -> PLC)
- Clearing consumption
accumulation 1 to 4 complete
- Consumption accumulation ON 1 to
4
Parameter
(HMI)
Parameters
- Power consumption
accumulation interval
- Power consumption
accumulation start time
(4) Drive fixed power consumption
- Stall torque for power
consumption
- Short-time rated output for
power consumption (L/H coil)
- Coil switch function ON/OFF
- Speed detection set value
- Base speed
Note
(1) The use of custom API library function (melReadData) allows you to obtain the present power consumption data and
accumulated power consumption data.
