Default Input Functions
The list below describes the factory default functions for each of these inputs. A logic input
hardware is active when current is flowing through its photo diode. Inactive logic input
hardware is open circuited (has no photo diode current). The active control logic polarity of
each input can be set by the corresponding DInp
X
Pol NV Parameter. In other words,
depending on the state of Dinp
X
Pol, a given hardware input driven active, will activate or not
activate a drive control function.
DINP1 (ENABLE)
Input 1
: The ENABLE control function mapped to this input
enables/disables the drive and resets the latched drive faults.
With default logic polarity (
DInp1Pol
= Normal), the drive can
enable when input 1 is activated (current flowing in the photo
diode) and will be disabled when open circuited. This input will
disable a drive independent of any other parameters. Successful
enabling requires no drive faults and
SWEnable
, SynqNet drive
enable active as appropriate.
Setting this input to the inactive state clears any latched drive
faults.
DINP2 ()
Input 2
: The control function mapped to this input
prevents further motion in the clockwise shaft motion direction
when activated by current flowing in the photo diode. This input
has no effect on motion in the counter-clockwise direction. This
function can be turned on or off by setting
EnhibitCW
.
DInp2Pol
sets the control logic active polarity for this hardware input.
This input is useful for a clockwise over travel limit switch. Broken
wire “failsafe” over travel limit switch operation requires that
DInp1Pol
be set to Invert by the user to change the factory
default.
NOTE
: For S200 drives with the SynqNet option, the base drive
function is turned off by
EnhibitCW
= Off. Over travel
limit switch inputs must be wired directly to J13 on the SynqNet
option card.
DINP3 (INHIBIT-)
Input 3
: This input operates symmetrically to DINP2 with the
INHIBIT- control function preventing further motion in the counter-
clockwise shaft motion direction. This function can be turned on
or off by setting
EnInhibitCCW
.
DInp3Pol
sets the control logic
polarity.
DINP4
(DIRECTION)
Input 4
: This input is the direction input when the drive is in
Position Mode with the
PosCmdSrc
set to Step & Direction. Open
circuit/no LED current positively increments the position
command/motor goes CW. Set up time for direction is 100 µs.
Minimum pulse width is 200 µs. Refer to DInp4.
Driving the General Purpose Inputs
Sinking Logic
For compatibility with sinking outputs, the DINP COM terminal is
connected to the positive terminal of a power source (4.0 to 30
VDC). The input (DINP1-4) is connected to the sinking logic
output of the field device as shown in the diagram below.
