8:PID control setting
Select process PID control output as the operating frequency. Generally it is used for
closed-loop control, such as constant pressure closed-loop control, constant tension closed-loop
control and other occasions. Select PID as the frequency source, you need to set E2 group "PID
function"parameters.
9:Remote communications setting
PI160 supports Modbus communication.

The instruction for use refers to F0.03.
When the frequency source auxiliary setting is used as overlays reference (Select
frequency source as master+auxiliary , master to master+auxiliary or auxiliary to
master+auxiliary ), you need to pay attention to:
1) When the frequency source auxiliary setting is set to digital reference, the preset
frequency (F0.01) does not work, user can adjust frequency by using ▲, ▼ keys (or multi-
function input terminals UP, DOWN) on the keyboard, adjust directly on the basis of master
frequency source.
2)When the frequency source auxiliary setting is set to analog input reference (AI1,AI2,
panel potentiometer) or pulse input reference, the frequency source auxiliary setting range for
the set 100% can be set by F0.05 and F0.06.
3)When the frequency source is set to pulse input reference, it is similar to analog
reference . Tip: Both master and auxiliary setting of frequency source can not be set in the same
channel, ie F0.03 and F0.04 can not be set as the same value, otherwise easily lead to confusion.

When the frequency source is set to "frequency overlay"(i.e. F0.07 is set to 1, 3 or 4),these
two parameters are used to determine the range of adjustment of frequency source auxiliary
setting.
F0.05 is used to determine the object corresponding to frequency source auxiliary setting
range, either the maximum frequency or the frequency source master setting, If the frequency
source master setting 1 is selected, so the frequency source auxiliary setting range will be
subject to the change of the frequency source master setting, it applies for when auxiliary
setting range is less than master setting range; If the frequency source master setting 2 is
selected, so the frequency source auxiliary setting range will be subject to the change of the
frequency source master setting, it applies for when auxiliary setting range is more than master
setting range;
Recommendation: frequency source master setting (F0.03) shall adopt analog
setting,frequency source auxiliary setting (F0.04) shall adopt digital setting.
