Analog input AI1
Analog input AI2
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

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

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.
