SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual
38
Note: pulse setting can only be set by multifunction input terminal HDI1 or HDI2. Moreover,
P5.00 setting of HDI1 or HDI2 should be set as high speed pulse input, and P5.35 should be
set as “Setting Input”.
4
Simple PLC program setting
If this frequency setting mode is chosen, the inverter is operated by simple PLC program.
It is needed to set up the parameters of PA Group “Simple PLC and multi-speed control group”
to determine given percentage and given frequency, the coincidence relation between plus
minus and rotating direction, and selection of acceleration and deceleration time as well. For
details, please refer to description of PA Group functions.
5
Multi-speed operation setting
The inverter is operated in the mode of multi-speed once this frequency setting mode is
chosen. It is needed to set up the parameters of P5 Group and PA Group “Simple PLC and
multistage speed control group” to determine the coincidence relation between given
percentage and given frequency.
6
PID control setting
Selection of this parameter means that the operation mode of inverter is process PID
control mode. In this case, it is required to set up P9 Group “PID control group”. The operation
frequency of inverter is the frequency value after the PID action. Please refer to the description
of P9 Group “PID functions” for the definition of PID giving source, assigned value, feedback
source and so on.
7
Remote communication setting
The frequency command is given in the communication mode by upper position machine.
For details, please refer to “CHV Series inverter ModBus Communication Agreement”.

When frequency command B serves as the independent frequency giving channel (i.e.
frequency source is selected as switching from A to B), its usage is the same as that of
frequency command A.
When Frequency Command B acts as overlap setting (i.e. frequency source is chosen as
A+B), it has particular features:
1. Input Setting (AI2, AI4): 100% set by Input Setting (AI2 and AI4) is corresponding to the
reference object chosen by P0.05. If it is required to adjust based on Frequency Command A,
the reference object should be set as Frequency Command A, and thus 100.0% that
Frequency Command B refers to is the setting value of Frequency Command A.
2. When frequency source is high speed pulse input (HDI2) setting, it is similar to analog
setting.
