Dedicated monitor function
3.10.2 Terminal 1 input voltage monitor
Voltage applied to terminal 1 (dancer roll position) is displayed in a monitor by setting
Pr. 52
= "26 or 27".
It is only displayed in DU/PU main monitor and is not output to terminal FM/terminal AM.
The displayed percentages [%] are the analog input values calibrated with
Pr. 917
and
Pr. 918
.
3.10.3 Winding diameter monitor
Calculated winding diameter in inverter is displayed in PU/DU monitor and output to terminal FM/AM.
Displayed increments is as follows in PU/DU.
3.10.4 Line speed pulse monitor function
The pulse train input values, which are used to set the line speed, can be displayed.
Monitoring is available when the following conditions are satisfied: the PID control for dancer control / winding diameter
calculation is valid, and the pulse train setting (
Pr. 763
= "1, 2") is selected for the line speed input selection. If the above
conditions are not satisfied, "0" is displayed.
The number of input pulses is displayed as an absolute value. The upper limit is 200Kpps.
The number of pulses is affected by the
Pr. 707 Sampling time for winding diameter calculation
and
Pr. 768 Line speed input filter
time constant
settings.
3.10.5 Multiple monitor (Pr. 52)
To select two monitors for adjustment simultaneously, set 3939 or greater number in
Pr. 52.
Selected two monitors can be
displayed using 4 digits. The monitor corresponding with the first two digits is displayed instead of current monitor, and the
monitor of the last two digits is displayed instead of voltage monitor.
Example) When
Pr. 52
= "4042"
First 2 digits are 40 (Winding diameter monitor)
Winding diameter monitor is displayed instead of current monitor
Last 2 digits are 42 (Line speed monitor)
Line speed monitor is displayed instead of voltage monitor
For 3-step monitor of FR-PU07, the monitors selected in
Pr. 52
are also displayed.
