4.2.17. “Password”
If a password is entered in parameter number 648, the UNIDEX 511 will prompt the user
for a password when turned on. An incorrect password will prohibit the user from
modifying system parameters and programs. A blank entry in parameter 648 will defeat
the password function. The settings for the password parameter are shown in Table 4-6.

Parameter # Range Default Value

4.2.18. “Abort on input high 0, 1-16”
Parameter 501 allows the user to define an input bit on the 16 IN/8 OUT I/O connector as
a global abort input. All enabled axes will ramp to a stop and “Abort Active” will be
displayed in the MDI window. This will occur when the input bit is in the logic “1” (+5 V
or high impedance) state. A parameter setting of 0 (the default) defeats the Abort input.
Parameter settings are given in Table 4-7.
