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
MAX.

WARNING! If parameter
0 V and analog input signal is lost (ie 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
Set parameter 3021 AI1 FAULT LIMIT
Set parameter 3001 AI<MIN FUNCTION
See selection AI1/JOYST.
Digital input DI3: Reference increase. Digital input DI4:
Reference decrease. Stop command resets the reference to
zero. Parameter 2205 ACCELER TIME 2
the reference change.
Digital input DI3: 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
TIME 2 defines the rate of the reference change.
Fieldbus reference REF1
Summation of fieldbus reference REF1 and analog input AI.
See section Reference selection and correction

Multiplication of fieldbus reference REF1 and analog input
AI1. See section Reference selection and correction
