AI1/JOYST
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
and
.
Note:
Parameter
.
WARNING!
If parameter
is set to
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
to 20% (2 V or 4 mA).
Set parameter
to 5% or higher.
Set parameter

DI3U,4D(R)
Digital input DI3: Reference increase. Digital input DI4:
Reference decrease. Stop command resets the reference to
zero. Parameter
defines the rate of
the reference change.

DI3U,4D
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
defines the rate of the reference change.
