Group F2 Input Terminal 
MD280 series inverter has 5 multifunctional digital input terminals (DI1 to 
DI5), of which DI5 can be used as high-speed pulse input terminal, and 
ME280 series inverter also has two analog input terminals (AI1 and AI2). 
 
Caution: 
1: When DI5 as high-speed pluse input terminal,set function setup of input 
terminal DI5 to zero(no function)so as to avoid malfunction. When DI5 is 
high-speed pluse input, it can be the frequency source, Frequency source 
upper limit, PID setup source, PID feedback source, and setup source of 
MS zero-segment. 
2: For the counter input and the length count input, please use DI5 when 
the pluse frequency is higher.When use low-speed pluse, and use DI1 to 
DI4.
