Actual signals and parameters
Description
Analog input AI1 as joystick. The minimum input signal runs the motor at the
maximum reference in the reverse direction, the maximum input at the
maximum reference in the forward direction. Minimum and maximum
references are defined by parameters
Note: Parameter 1003 DIRECTION must be set to REQUEST.

WARNING! If parameter 1301
signal is lost (i.e. 0 V), the rotation of the motor is reversed to the maximum
reference. Set the following parameters to activate a fault when analog input
signal is lost:
Set parameter 1301 MINIMUM AI1 to 20% (2 V or 4 mA).
Set parameter 3021 AI1 FAULT LIMIT to 5% or higher.
Set parameter 3001 AI<MIN FUNCTION to FAULT.
See selection AI1/JOYST.
Digital input 3: Reference increase. Digital input DI4: Reference decrease.
Stop command resets the reference to zero. Parameter
TIME 2 defines the rate of the reference change.
Digital input 3: Reference increase. Digital input DI4: Reference decrease.
The program stores the active speed reference (not reset by a stop
command). When the drive is restarted, the motor ramps up at the selected
acceleration rate to the stored reference. Parameter
defines the rate of the reference change.
Fieldbus reference REF1
Summation of fieldbus reference REF1 and analog input AI. See section

Digital input 3: Reference increase. Digital input DI4: Reference decrease.
Stop command resets the reference to zero. The reference is not saved if the
control source is changed (from EXT1 to EXT2, from EXT2 to EXT1 or from
LOC to REM). Parameter
