Description
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 2205 ACCELER TIME 2 defines the rate of
reference change.
Fieldbus reference REF1.
Summation of fieldbus reference REF1 and analog
input AI. See section Reference selection and
correction in ACS355 User's manual
(3AUA0000066143[English]).
Multiplication of fieldbus reference REF1 and analog
input AI. See section Reference selection and
correction in ACS355 User's manual
(3AUA0000066143[English]).
• 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
the reference change.
• Digital input DI3: Reference increase.
• Digital input DI4: Reference decrease.
Program stores the active speed reference (not reset
by a stop command). When you restart the inverter,
the motor ramps up at the selected acceleration rate to
the stored reference.
Parameter 2205 ACCELER TIME 2 defines the rate of
the reference change.
