Baldor NextMove PCI, Installation Manual

Page: 25 / 92

Input / Output 4-9 MN1903
Inputs can be shared between axes, and are programmable in MintMT (using the keywords
INPUTACTIVELEVEL , INPUTMODE , INPUTPOSTRIGGER and INPUTNEGTRIGGER ) to
determine their active level and if they should be edge triggered. Four of the inputs,
DIN0-DIN3, are fast position latch inputs.
There are a total of 12 general purpose digital outputs. An output can be configured in MintMT
as a general purpose output, a drive enable output or a general error output. Outputs can be
shared between axes and are programmable, using the MintMT keyword
OUTPUTACTIVELEVEL
, to determine their active level.
The outputs are driven by a module fitted to the NextMove PCI card. Two module types are
available:
H
Current sourcing, PNP Darlington with overcurrent and short circuit protection
(OPT025-507, fitted as standard).
H
Current sinking, open drain N-channel MOSFET (OPT025-508).
If further digital outputs are required, an expansion card is recommended (see section A.1.1).
If an expansion card is not available, unused stepper axes can be configured as Off, and their
direction and pulse output pins then used as outputs. See the MintMT keywords
CONFIG
and
STEPPERIO .
