Product Overview
Metering
Power monitoring parameters include:
•
Three-phase current
•
Three-phase voltage
•
Power in MW
•
Power usage in MWh
•
Power factor
•
Motor thermal capacity usage
•
Elapsed time
•
Motor speed (full speed %, with use of optional tachometer input)
Notes:
1.
Voltage measurement is not available during the braking operation of the
SMB Smart Motor Braking, Accu-Stop, and Slow Speed with Braking
control options.
2.
The elapsed time and MWh values are automatically saved to memory
every 12 hours.
3.
Motor thermal capacity usage is determined by the built-in electronic
thermal overload. An overload fault occurs when this value reaches 100%.
I/O
The SMC Flex has the ability to accept up to two (2) inputs and four (4) outputs
controlled over a network. The two inputs are controlled at terminal 16 (Option
Input #1), and terminal 15 (Option Input #2). For these two inputs, refer
to
for the parameter settings and refer to
for the bit
identification. By using these two terminals as inputs, the Stop Input will need to
be programmed to meet the desired stop functionality.
The four (4) outputs are Aux #1, Aux #2, Aux #3 and Aux #4. All auxiliary
contacts are programmable to the function found on
. If programmed to
Network or Network NC, they can be controlled over a Network. Please see
which defines the Logic Command Word (Control).
TIP
For MV applications, some of the I/O are assigned to specific functions. Please
refer to
for additional details.
