IX. Descriptions of Functions
CD000 Main Frequency
**
Set Range: 0.00-400.00 Hz Unit: 0.01 Hz Factory Setting: 0.00
In the digital operator mode, the inverter will run at the set value of CD000.
During running, the operating frequency can be changed by pressing ▲ or ▼.
During multi-speed running, the main frequency is taken as the frequency of
Speed 1.
In the external control multi-speed mode, if CD034 is set to 1, i.e. given by an
external terminal, Speed 1 will be given by the analog of the external terminal.
The setting of main f requency is limited by the maximum operating
frequency.
The related parameters of CD034, CD076 are adjustable during operation.
CD001 Max Voltage
Set Range: 0.1V-* Unit: 0.1V
Factory Setting: 220/380
This parameter should be set according to the rated value of the motor’
s nameplate. The factory setting is 380V for 380V class motor and 220V for
220V class motor. The setting range of this parameter is restricted by the
voltage rating of the inverter. In case of the motor relatively far away from the
inverter this set value can be increased properly.
CD002 Base Frequency
Set Range: 0.01—400.00 Hz Unit: 0.01Hz Factory Setting: 50.00
This parameter must be set according to the rated f requency of operating
voltage on the motor’s nameplate. Under normal conditions do not change the
set value of base frequency at will. If it is equipped with a special motor this
value should be set properly according to the characteristics of the motor’s
parameters. Otherwise it may cause the damage to the equipment.
CD003 Intermediate voltage
Set Range: 0.1V—*
Unit: 0.1V Factory Setting: *
This parameter is set for an intermediate voltage value of arbitrary V/F curve.
If it is set improperly, it will cause over-current or under-torque of the motor,
or even tripping of the inverter. When the intermediate frequency is increased
the voltage will increase the output torque and at the same time also the output
current. When changing this parameter please pay attention to monitoring the
output current to avoid the inverter’s tripping due to over-current.
This set value of intermediate voltage is limited by the set value of max
voltage. When the voltage is increasing to a certain value at intermediate
