More about control inputs:
"PULSE & DIR": A drive has a pulse and a direction input. These inputs are like a stepper motor
interface. The incoming pulses (frequency) determine the velocity of the motor and
the direction input the sense (CW, if high level and CCW if low level) of motor shaft
rotation.
"STOP": If the input is activated the motor will decelerate from the actual velocity to rest at the
rate defined by
SPEEDREFDECELTIME
(unless
SPEEDREFSOURCE
is set to 1 - see
the help file) and keep the reached position in controlled manner. The function is
independent of the actual operating mode (current- or velocity mode). This function
can both be activated by hardware input DIN 2 (X3.12), the DIP-switch AS1.5 or by
software.
"QUIT": If the input is activated the current positioning process will be aborted. A restart
(trigger) is required in order to continue the positioning after the quit input has been
reset to zero
"DIN x": There are up to 4 machine inputs available.
Inputs X3.16 (DIN 6) and X3.17 (DIN 7) can either be used together with the PLC
program (default) or for selection of the programmed point-to-point move. If more
than three programmed point-to-point moves are needed, the alternative functions of
the inputs X3.10 (DIN 0) and/or X3.11 (DIN 1) must be used.
Please note , that the limit switch function is not available in this case. To substitute
(or add-on) the function of the hardware limit switches, software limit switches can
be defined.
"FRESET": If the input is activated, the drive will attempt to cancel all types of error and then re-
enable.
"HOMEINPUT": This input is for determination of the home position. It is an edge-controlled input
(Position Control) and the input function can be activated by a rising or falling signal edge.
"PRESETTRIGGERINPUT": With this input a programmed point-to-point move will be started. If the input
(Position Control) will be activated, the position move addressed with the MaI´s will be executed. It is
an (rising) edge controlled input.
