V/F pattern
(3) Base frequency voltage setting
(Pr. 19)
Use
Pr. 19 Base frequency voltage
to set the base voltage (e.g. rated motor voltage).
If the setting is less than the power supply voltage (Twice the amount of the power supply voltage for single-phase 100V
power input model), the maximum output voltage of the inverter is as set in
Pr. 19
.
Pr. 19
can be utilized in the following cases.
(a) When regeneration is high (e.g. continuous regeneration)
During regeneration, the output voltage becomes higher than the reference and may cause an overcurrent trip
(E.OC ) due to an increased motor current.
(b) When power supply voltage variation is large
When the power supply voltage exceeds the rated voltage of the motor, speed variation or motor overheat may be
caused by excessive torque or increased motor current.
NOTE
When Advanced magnetic flux vector control or General-purpose magnetic flux vector control is selected,
Pr. 3, Pr. 47
and
Pr. 19
are invalid and
Pr. 83
and
Pr. 84
are valid.
Note that
Pr. 3
or
Pr. 47
value is made valid as inflection points of S-pattern when
Pr. 29 Acceleration/deceleration pattern
selection
= "1" (S-pattern acceleration/deceleration A).
Changing the terminal assignment using
Pr. 178 to Pr. 184 (input terminal function selection)
may affect the other
functions. Set parameters after confirming the function of each terminal.
Parameters referred to
Pr. 14 Load pattern selection
Pr. 29 Acceleration/deceleration pattern selection
Pr. 83 Rated motor voltage, Pr. 84 Rated motor frequency
Pr. 178 to Pr. 184 (input terminal function selection)
General-purpose magnetic flux vector control
Advanced magnetic flux vector control
