5.2.3. Setting the Polarity (A or B contact) of the Input Ports
l The shipping set of polarity for all CN2 input signal ports is A contact.
l The polarity of some input signal ports can be changed to B contact in an ESA25 Driver Unit.
l The ports of which the polarity can be changed are only four signals below. The other ports are
fixed to A contact.
EMST : Emergency stop
HLS : Home limit switch
OTP : + direction overtravel limit switch (CW direction)
OTM : - direction overtravel limit switch (CCW direction)
l The polarity can be changed by the parameter AB.
l The password input is necessary before inputting AB parameter.
l Table 5-6 shows the data and port. Refer to “Setting Example” below and the explanation of AB
parameter.

l Meaning of data
0 = A contact (normally open)
1 = B contact (normally close)
X = Cannot be changed just after read out the setting of polarity.
When setting polarity, inputting X means no change of polarity of the port.
