Direction will reverse if the speed reference is negative;
REF SELECT must be "AI5".
See selection DI2. Instead of a digital input, the command comes from

Follows the direction command from the master drive.
Defines the source or constant for selection PARAM 10.05 of
EXT1 STRT/STOP
Parameter index or a constant value:
- Parameter pointer: Inversion, group, index and bit fields. The bit
number effective only for blocks handling boolean inputs.
- Constant value: Inversion and constant fields. Inversion field must
have value C to enable the constant setting
The speed reference to the winder is scaled to be proportionate to the
maximum web speed. The winder control program uses the input web
speed and the actual diameter to calculate the rotational speed
reference (rpm reference) to the drive.
Speed matching the surface speed of the Winder or Unwind Core to
the line speed is essential for tension regulation and diameter
calculation accuracy. Speed matching guarantees that the web will be
running the same rate throughout the machine, enabling the tension or
dancer regulator to control surface tension with less trim and greater
accuracy.
Parameter group 11 defines the speed reference source and scaling
parameters.
Select the required source for the web speed e.g. AI or Fieldbus. The
Analog Input should be scaled to be 100% at maximum web speed
(10 VDC if AI (voltage input) is used and 20 mA if AI (current input) is
used.
For example, AI1 should be 10 VDC at 1000 ft/min (304.8 m/min) line
speed if 1000 ft/min (304.8 m/min) is the maximum web speed.

Analog input AI1 (voltage).
Analog input AI2 (current).
Analog input AI3 (current).
Analog input AI5 (voltage or current). If joystick operation is desired,
set
10.02
EXT1 DIRECTION to "AI5". With this done, when the input is
less than 0 VDC the direction is reverse. When the input is greater
than 0 VDC the direction is forward.
Analog input AI6 (voltage or current).
