Hitachi hitachi series inverter 사용자 설명서

 

32 

The inverter can store up to 16 different target 
frequencies (speeds) that the motor output uses for 
steady-state run condition. These speeds are accessible 
through programming four of the intelligent terminals as 
binary-encoded inputs CF1 to CF4 per the table to the 
right. These can be any of the six inputs, and in any 
order. You can use fewer inputs if you need eight or 
fewer speeds. 

 

NOTE: When choosing a subset of speeds to use, 
always start at the top of the table, and with the 
least-significant bit: CF1, CF2, etc. 

 
 
 
 
 

The example with eight speeds in the 
figure below shows how input switches 
configured for CF1–CF3 functions can 
change the motor speed in real time. 
 

NOTE: Speed 0 depends on 

A001

 

parameter value.

Notes: 
•  When programming the multi-speed settings, be 

sure to press the SET key each time and then set 
the next multi-speed setting. Note that when the 
key is not pressed, no data will be set. 

•  When a multi-speed setting more than 50Hz 

(60Hz) is to be set, it is necessary to program the 
maximum frequency 

A004

 high enough to allow 

that speed
