Description
Analog input AI1 as joystick. At maximum reference,
the
• minimum input signal runs the motor in reverse
direction.
• maximum input signal runs the motor in forward
direction.
The minimum and maximum references are defined by
parameters 1104 REF1 MIN and 1105 REF1 MAX,
Note: To control direction, set the parameter
DIRECTION = REQUEST
Par. 1301 = 20%, par 1302 = 100%

WARNING! If parameter 1301 MINIMUM AI1 is
set to 0 V and analog signal is lost (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:
• 1301 MINIMUM AI1 = 20% (2 V or 4 mA).
• 3021 AI1 FAULT LIMIT = 5% or higher.
• 3001 AI<MIN FUNCTION> = FAULT.
For parameter details, see ACS355 User's manual
(3AUA0000066143[English]).
See select AI1/JOYST.
Digital input DI3: Reference increase.
Digital input DI4: Reference decrease.
Stop command resets the reference to zero.
Parameter 2205 ACCELER TIME 2 defines the rate of
reference change.
