Specification of high-performance vector convertor
The function code is only valid when the the frequency source selection is main and auxiliary
calculation.
When the frequency source is the main and auxiliary calculation, P0-21, as an offset frequency, And
primary and secondary operation are used as the final result of the superposition frequency setpoint to
make the frequency setting more flexible.
Resolution of frequency command Factory default
P0-22
Setting
range
This parameter is used to identify all frequency-dependent function code resolution.
When the frequency resolution is 0.1Hz when, VFD maximum output frequency can reach 3200Hz.
When the frequency resolution is 0.01Hz, the maximum output frequency VFD is 600.00Hz.
Attention: When you modify the function parameters, all the parameters related decimal places of
frequency will change. The corresponding frequency values shall also change, pay special attention when
using.
Digital setting frequency stop memory selection
P0-23
Setting range
This function is only effective when the frequency source is set as numbers.
"No memory" means after inverter stops, digital set frequency value back to P0-08 (preset frequency)
values. Keyboard ▲, ▼ keys or terminals UP, DOWN frequency correction performed is cleared.
"Memory" means after inverter stops, digital set frequency reserved for the last stop time set frequency.
Frequency keyboard ▲, ▼ keys or terminals UP, DOWN conduct correction remains valid.
Motor selection
P0-24
Setting
range
VFD supports drag-sharing drive 2 motors application. 2 motors can respectively set the motor
nameplate, independent tuning parameters, choose a different control mode, independent setting
performance related parameters and others.
Corresponding function parameter group of motor 1 is P1 group and P2 group. Corresponding
function parameter group of motor 2 is A2 group.
The user to select current motor through P0-24 function code, you can also switch the motor through
the input terminal DI digital. When the function code selection and terminal selection have contradiction,
the terminal selection shall prevail.
Acceleration/Deceleration time reference frequencies
P0-25
Setting
range
Acceleration and deceleration time means the acceleration and deceeration time from zero frequency
to P0-25 setting frequency. Figure 6-1 is the Aceleration and Deceleration Time Schematic.
When P0-25 is selected as 1, deceleration time and frequency related to the set. If setting frequency
change frequently, the motor acceleration is changable, so we need to pay attention to the application.
