10.133 (ID 377) AI1 Signal Selection
Location in the menu:
P2.2.8 (Standard Application)
P2.2.3
(Local/Remote Control Application, Multi-step Speed Control Application)
P2.2.15 (PID Control Application)
P2.2.2.1 (Multi-purpose Control Application, Pump and Fan Control Application)
Use this parameter to connect the AI signal to the analog input of your selection.
TTF programming method must be applied to this parameter see
10.626 "Terminal to Function" (TTF) Programming Principle ).
10.134 (ID 384) AI1 Joystick Hysteresis
Location in the menu:
P2.2.2.8
(Multi-purpose Control Application)
Use this parameter to set the joystick hysteresis.
This parameter defines the joystick hysteresis between 0–20%.
When the joystick or potentiometer control is turned from reverse to forward, the output frequency falls linearly to the selected
minimum frequency (joystick/ potentiometer in center position). It stays there until the joystick/potentiometer is turned towards
the forward command. It depends on the amount of joystick hysteresis defined with this parameter, how much the joystick/potenti-
ometer must be turned to start the increase of the frequency towards the selected maximum frequency.
If the value of this parameter is 0, the frequency starts to increase linearly immediately when the joystick/potentiometer is turned
towards the forward command from the center position. When the control is changed from forward to reverse, the frequency fol-
lows the same pattern the other way round.

Illustration 59: An Example of Joystick Hysteresis
In the example figure, the value of parameter ID 385 ( Sleep limit ) = 0
10.135 (ID 385) AI1 Sleep Limit
Location in the menu: P2.2.2.9 (Multi-purpose Control Application)
Use this parameter to set the sleep limit. The AC drive stops automatically if the AI signal level falls below the value set with this
parameter.
