Description
A pulse input for frequency
setting. (Take note that the
internal circuit is different
from input terminals S7/
EB.)
A pulse input for frequency
setting. (Take note that the
internal circuit is different
from input terminal RP.)
Select 2 functions from
among 43, and allocate
them to terminals P1
through P2. Both sink and
source logics are
supported. For details, refer
to "Connection to
Programmable Controller
(PLC)" on page 2-22.
Enabled when the EDM
function selector switch is
ON. For details, refer to
"Safety Function" on page
5-167.
Select the desired functions
from among 43 functions,
and allocate them to these
terminals.
SPDT contact.
The factory default of Relay
Output (MA, MB) Contact
Selection (C036) is NC
contact between MA-MC,
and NO contact between
MB-MC.
