Operation Monitoring - YASKAWA VS-616PS5 Series Quick Start Manual

Operation Monitoring

In the Quick Start program, most of the monitoring parameters are available to peek into what the inverter is doing
internally. These parameters, the "U" parameters may be used to monitor normal operation or to troubleshoot
abnormal operation. There are three groups:
1. U1 – Monitor
2. U2 – Fault Trace
3. U3 – Fault History
Monitor Parameters
Number
U1-01 Speed Reference
U1-02 Output Frequency
U1-03 Output Current
U1-05 Motor Speed
U1-06 Output Voltage
U1-07 DC Bus Voltage
U1-08 Output Power

Number
U1-10 Input Terminal Status
Parameter U1-10 represents the status of the input terminals with a letter "C" followed by a series of vertical bars.
The bars represent terminals 1 through 8 from right to left.
The first character in the digital operator display is a letter "C":
If terminals 1, 2, 5, and 8 are ON, the display will look like this:
Number
U1-11 Output Terminal Status
Parameter U1-11 represents the status of the output terminals with a letter "o" followed by a series of vertical bars
in a manner much like U1-10 displays the input terminals. The display is for the following outputs:
