Upper limit
frequency source
Panel potentiometer setting
Setting upper limit frequency. The upper limit frequency can be set from either
digital setting (F0.21) or analog input channels. If the upper limit frequency is set from
analog input, the set 100% of analog input is relative to F0.21.
To avoid the "Runaway", the setting of upper limit frequency is required, when the
inverter reaches up to the set upper limit frequency value, the inverter will remain
operation at the upper limit frequency, no further increase.
F0.23 (lower limit frequency) to
F0.19(maximum frequency)
0.00Hz to F0.21 (upper limit
frequency)
When the frequency command is lower than the lower limit frequency set by F0.23,
the inverter can shut down, and then run at the lower limit frequency or the zero speed;
the running mode can be set by F7.18.
By changing the parameters, the motor steering can be achieved without changing
the motor wiring, which acts as the adjustment of any two lines(U, V, W) of the motor to
achieve the conversion of the motor rotation direction.
Note: after the parameter is initialized, the motor running direction will be restored to
its original status. When the system debugging is completed, please use with caution
where the change of motor steering is strictly prohibited.
