Liberty MDrive Ethernet TCP/IP
I/O Operation
The LMD TCP/IP products feature the following I/O points:
• Three (3) general purpose inputs
• One (1) 12-bit analog input (not available on the Absolute Encoder version)
• One (1) high-speed signal output
All of the I/O points are functionally configured in software using MCode. For detailed
descriptions of each I/O configuration parameter, refer to the MCode Programming and
Reference Manual, available for download from:
https://novantaims.com/dloads/
General Purpose Inputs
The general purpose inputs are +5 to +24 VDC tolerant optically isolated inputs with
programmable functions and dedicated alternate functions.
The function and active logic state is defined using the
INPUT _ SETUP
parameter (
IS
) as:
IS=[POINT],[FUNCTION],[ACTIVE]
Point
Function
Active
2, 3, 4
0 = General Purpose
1 = Home
2 = Limit +
3 = Limit –
4 = G0
5 = Soft stop
6 = Pause program
7 = Jog +
8 = Jog –
11 = Reset
13 = Step (IN3)/Direction (IN4)
14 = ENC A (IN3)/ENC B (IN4)
15 = StepUp (IN3)/StepDown (IN4)
0 = Low True
1 = High True
The logic state of each input is read using the
I2
,
I3
, and
I4
flags. The inputs may be read as a
4-bit word using the
IT
variable.
