Setting 100 to 1B2: Functions 0 to B2 with Inverse Output
These settings have the same function as settings 0 to B2, but with inverse output. Set as 1oo, where the “1” indicates inverse
output and the last two digits specify the setting number of the function.
Examples:
• Set 108 for inverse output of “8: During Baseblock (N.O.)”.
• Set 14A for inverse output of “4A: During KEB Operation”.
