■
L8-19 Overheat Frequency Reference Reduction Level
Setting Range: 0.0 ~ 100.0 % of maximum frequency
Factory Default: 20.0 % of maximum frequency
When the heatsink temperature reaches the OH Pre-alarm level (L8-02) and the Overheat Pre-Alarm Operation Selection parameter is set
for Alarm and Reduce (L8-03 = “4: OH Alarm and Reduce”), the L8-19 parameter sets the amount of speed decrease that will be applied
to the Speed Command in order to lower the heatsink temperature. The decrease in speed will lower the current being switched and
conducted by the heat producing output transistors of the iQpump drive.
Parameter L8-19 is set in percentage of maximum frequency (E1-04).
◆ o1 Monitor Configuration
■
o1-01 User Monitor Selection
Setting Range: 6 ~ 94
Factory Default: 6
■ o1-02 Power-On Monitor
When the iQpump drive is powered up, three monitors are displayed on the digital operator. The first and largest monitor is the “Power-
On” monitor. The factory default “Power-On monitor” is Speed Command (U1-01). Below the Speed Command monitor are the next two
sequential monitors, Output Frequency (U1-02) and Output Current (U1-03). Pressing the INCREASE key once scrolls the monitors to
show the User Monitor as selected by o1-01. The factory default for o1-01 is the Output Voltage monitor (U1-06).
