3.4.3.2. Setting Polarity of Input Port (Normally Open or Normally Closed Contact)
l The polarity of some input signal ports may be set either the normally open or closed contact.
l The shipping set of polarity for all the CN2 input ports is the normally open contact. .
l Parameter AB sets the polarity of input ports.
l You need the password before inputting the parameter AB.
l The signals that can select the polarity are limited to EMST, HLS, OTP and OTM.
(OTP and OTM inputs are only available for the types of 3, 4 and 7 in case of B3 and 23 Driver
Units.)

Signal Name
SVON EMST IOFF HLS HOS CLR OTM OTP
l Meaning of data
0 = normally open contact: 1 = normally closed contact
X = When inputting X, X denotes “no polarity change.” When it is indicated on the
display, the X denotes “inhibit switching polarity.”
u Setting Example
l This example shows to set the normally closed contact for EMST (Emergency stop).
(1) Input a code key while pressing SHIFT
key.

0
?
SHIFT
(2) Input readout command for the parameter AB inorder to check current polarity setting.
(The example shows the all input ports are set to the normally open contact.
