• FREQUENCY : This message displays the frequency (in Hz). Frequency is calculated
from the phase A-N voltage (when setpoint

is “Delta”). A value of “0.00” is shown if there is insufficient voltage applied to
the PQMII’s terminals (less than 30 V on phase A).
• FREQ MIN : This message displays the minimum frequency measured as well as the
time and date at which the minimum frequency occurred.
• FREQ MAX : This message displays the maximum frequency measured as well as the
time and date at which the maximum frequency occurred.

• PULSE INPUT 1(4) : These messages display the accumulated value based on total
number of pulses counted since the last reset. One switch input pulse is equal to the

The units shown after the value are as defined in the
PULSE INPUT UNITS
setpoint in the
same menu. The displayed value rolls over to “0” once the value “4294967295”
(FFFFFFFFh) has been reached. To use this feature, the “C” (control) option must be
installed and one of the PQMII switch inputs must be assigned to “Pulse Input 1(4)”
function. The switch input will then count the number of closures or openings
depending upon how the switch is configured; see
Switch Inputs
on page 5–21 for
details. The minimum timing requirements are shown in FIGURE 6–2: Pulse Input
