When the inverter is used for the loads of kinds of fan and pump CD122 can
be set to 120. When the current of the inverter is greater than 120% the output
frequency will decrease and the current will also decrease accordingly. After
the current returns to normal the frequency will return to normal slowly, so as
to achieve the stall prevention f unction. The decreasing speed of the frequency
is determined by CD127. For the Related parameters refer to CD 122.
CD127 Decel. Time for Stall Prevention at Constant Speed
Factory Setting: 5.0
When the inverter is set for fault restart and if it has a fault trip with the time
exceeding the set value of CD128 the inverter will restart. When using this
f unction pay more attention to the safety.
CD128 Fault Restart Time Factory Setting: 1.0
When the starting mode of the inverter is set to f requency track there is a
process of voltage rise during the frequency track. When the voltage is rising
rapidly the current will be higher and the tracking process will be faster.
When the voltage is rising slowly the current will be lower and the tracking
process will be slower. In general practice this value of CD129 is set lower for
the inverter of smaller power and set higher for the inverter of larger power.
CD129 Voltage Rise Time during frequency track Factory Setting: 5
It is set according to the rated voltage value of the nameplate of the motor. For
the inverters of 230V class the factory setting is 220, while for the inverters of
400 V class the factory setting is 380.
CD130 Rated Motor Voltage Unit: 0.1V Factory Setting: *
It is set according to the rated value of the nameplate of the motor. This
parameter can be used to restrict the output current of the inverter to prevent
over-current and protect the motor. If the current of the motor has exceeded
this value the inverter of AC motor will turn to self-protection.
CD131 Rated Motor Current Unit: 0.1A Factory Setting: *
This parameter is set for the number of the motor’s pole according to the
nameplate of the motor.
