When the motor capacity is small compared to the Inverter
capacity, false open-phase detection mayoccur or open-
phase cannot be detected. In this case, disable the detection
function by setting L8-07
to 0.

OL2 characteristics selection at low speeds
When using OL2 to trip at low speeds (less than 6 Hz)
despite a light load, set L8-17 to 1 (with carrierfrequency
reduction) and L8-19 (OL2 characteristics selection at low
speeds) to 0 (disabled).However, do not set l8-19 to 0 for
400 V class, 185 to 300 kW Inverters.Do not L8-17 and
L8-19 to 0 at the same time when using V/f control and
open loop vector control.Reduce the carrier frequency
(C6-01) to 2 kHz when continuously operating at low
speeds with heavyloads when using flux vector control.

In operation mode, the frequency reference, output frequency,
output current, and output voltage canbe monitored immediately
if the factory settings are being used. One of these four
values, the outputvoltage, can be changed to a different
value.When you want to monitor a value other than the
output voltage, set that number in constant o1-01.Use
the last two digits from the “U1 Monitor” list (U1-jj) to
select a value.

When the 40 to 39,999 range is used, any unit can be set for
the reference frequency.For example, the frequency reference
can be displayed or set in units such as mm/s or m/min to
coincidewith the linear operating speed of the machine.
