A latched Precise Start only requires a pulse
of 3ms on T18 or T19.
When using for 1-83 [1] or [2]:
When the reference is reached, the
frequency converter will internally enable
the Precise Stop signal. This means that the
frequency converter will do the Precise
Stop when the counter value of 1-84 Precise
Stop Counter Value is reached.
Sends a latched stop signal when the
precise stop function is activated in
1-83 Precise Stop Function. The Latched
Precise stop inverse function is available for
terminals 18 or 19.
This function makes it possible to give an
external fault to the drive. This fault is
treated in the same way as an internally
generated alarm.
INCREASE signal to the Digital Potenti-
ometer function described in parameter
group 3-9*
DECREASE signal to the Digital Potenti-
ometer function described in parameter
group 3-9*

When enabled, it inverts the resulting error
from the process PID controller. Available
only if "Configuration Mode" is set to
"Surface Winder", "Extended PID Speed OL"
or "Extended PID Speed CL".
When enabled, resets the I-part of the
Process PID controller. Equivalent to
7-40 Process PID I-part Reset. Available only
if "Configuration Mode" is set to "Surface
Winder", "Extended PID Speed OL" or
"Extended PID Speed CL".
When enabled, enables the extended
process PID controller. Equivalent to
7-50 Process PID Extended PID. Available only
if "Configuration Mode" is set "Extended
PID Speed OL" or "Extended PID Speed CL".
All Digital Inputs can be set to PTC Card 1
[80]. However, only one Digital Input must
be set to this choice.
The functionality is the same as the
according control word bit of the Profibus/
Profinet option.
