Digital inputs
MK3A is a 10pole terminal block with 8 digital
inputs (I1–I8) and 2 terminals for 24 V supply (See
Supply voltages on page 12).
The digital inputs are used by the SyncPos appli-
cation program and are therefore free progra-
mable. All the inputs can also be assigned func-
tions by the following parameters:
I_BREAK (105) I_BREAK I_BREAK interrupt a running
I_BREAK I_BREAK
program
I_CONTINUE I_CONTINUE
I_CONTINUE (106) I_CONTINUE I_CONTINUE restart interrupted

I_ERRCLR I_ERRCLR

I_REFSWITCH I_REFSWITCH
I_REFSWITCH I_REFSWITCH I_REFSWITCH (45) home switch
Only two of the inputs are assigned a specific
function by parameter:
• • • • • I5 I5 I5 I5 I5 is used as marker input for the Master
when "External marker signal" is selected in
parameter SYNCMTYPM SYNCMTYPM (60). SYNCMTYPM SYNCMTYPM SYNCMTYPM
• • • • • I6 I6 I6 I6 I6 is used as marker input for the Slave when
"External marker signal" is selected in param-

Digital outputs
MK3C is a 10pole terminal block with 8 digital out-
puts and 2 terminals for 24 V supply (See Supply
voltages on page 12).
The digital outputs are controlled by the SyncPos
application program and are thus free
programable.
All the outputs can also be assigned functions by
the following parameters:
O_AXMOVE (64) O_AXMOVE O_AXMOVE O_AXMOVE O_AXMOVE axe is moving
O_BRAKE (48) O_BRAKE O_BRAKE O_BRAKE O_BRAKE activation of mechanical
brake
O_ERROR (108) O_ERROR O_ERROR O_ERROR O_ERROR fault indication

Encoder interface 1
MK3B is a 8pole terminal block with 6 terminals
for the encoder signals and 2 terminals with 5 V
supply.
(See Supply voltages on page 12).
Encoder interface 1 can be used for one of the
following 2 functions:
• • • • • Master encoder input (incremental or abso-
lute) for synchronizing.
• • • • • Virtual master encoder output (incremental).
The table below shows the function of each termi-
nal in the 3 possible modes. (See fig. 1)
options except on the first and the last station
connected in the network. See also connection
example on page 16 and 17.
Encoder interface 2
MK3D is a 8pole terminal block with 6 terminals
for the encoder signals and 2 terminals with 5 V
supply
(See Supply voltages on page 12).
Encoder interface 2 can be used for one of the
following 2 functions:
• • • • • Slave encoder input (incremental or absolute)
for synchronizing.
• • • • • Feedback encoder input (incremental or ab-
solute) for positioning.
The table below shows the function of each
terminal in the 2 possible modes. (See fig. 2, next
page)
