NO.6 Detailed Function Description
In case that frequency option is set by keyboard, the frequency operates with set value of
P003. During operating, the current operating frequency can be changed with keys ▲ and ▼.
In multi-segment operation, main frequency is taken as frequency I. If P002 is set as 1, i.e.
the external analog quantity is set, the frequency I is set by analog quantity of external
terminals. Main frequency setting is limited by maximum operating frequency.
Relevant parameters: P002 and P080. These parameters are adjustable during operating.
This setting must be conducted as per the motor’s rated running voltage frequency on motor
nameplate. Generally, the frequency setting value shall not be changed at will. In case of
being equipped with special motor, please set properly as per the motor parameter
characteristics, otherwise, the equipment will be damaged.
Maximum operating
frequency
This parameter decides the maximum operating frequency of the inverter.
This parameter can set the intermediate frequency value in any V/F curve. Improper setting
will cause insufficient startup torque of inverter or motor overcurrent and even tripping of
inverter. The setting value of intermediate frequency is limited by that of reference frequency.
This parameter decides the minimum startup frequency value in V/F curve.
This value shall be set as per rated value on motor's nameplate. The ex-factory value of
380V grade is 380V while that of 220V grade is 220V. This parameter setting range is limited
by voltage grade of inverter. And at the sites where motor is relatively far away from inverter,
this value can be appropriately increased.
