NOTE: On the Standard
MForce
MicroDrive,
when
configured
as outputs, the I/O
set is sinking ONLY!
The Plus 2 Models add
the functionality of I/O
Power, which enables
the user to use all the
outputs, both Standard
and Enhanced, as
Sinking or Sourcing.

Active States Defined
The Active State determines at what voltage level the input will be active.
Active HIGH ........................................ The input will be active when +5 to +24 VDC is applied to the input.
Active LOW .......................................... The input will be active when it is grounded (0 VDC).
Active LOW example:
IO 1 is to be configured as a Jog– input which will activate when a switch is toggled to ground (Sinking Input):
S1=8,0,0
Active HIGH example:
IO 4 is to be configured as a Home input which will activate when instructed by a PLC (+24VDC Sourcing
Input):
S4=1,1,1
MForce MicroDrive Digital Output Functions
The MForce MicroDrive Outputs may be configured as general purpose or set to one of two dedicated functions,
Fault or Moving. These outputs will sink up to 600 mA (one channel of two banks) and may be connected to an
external VDC source. See Output Functions Table and I/O Ratings Table.
The outputs are set using the "S" command (See MCode Software Reference Manual for precise details on this
command). The command is entered into the IMS terminal or program file as S<IO point>=<IO Type>,<Active
State><Sink/Source>.
Example:
S9=17,1,0
S3=18,0,0
Description
Sets I/O 7 and 8 to receive step and
direction inputs from an external source.
The motion will occur based on the input
frequency seen at I/O 7 in the Direction
relative to the logic state of I/O 8. The
step rate will be based upon the ratio set
by Clock Ratio (CR)
Sets I/O 7 and 8 to receive Channel A
and Channel B Quadrature inputs from
an external source such as an encoder.
The motion will follow the Quadrature
Input.
Sets I/O 7 and 8 to receive Clock
Up/Clock Down inputs from an external
source. The motion will occur based
upon the input clock frequency in the
direction relative to the input being
clocked. The step rate will be based
upon the ratio set by Clock Ratio (CR)
Description
The Capture input is a momentary
high speed input that operates with
the Trip Capture (TC) variable to run
a subroutine upon the trip. It feature
variable input filtering ranging from 50
nS to 12.9 µS
