3.6.2  Digital output (DOUT)  
Number: 1 
Parameter range:  r0730 – P0748 
Function chart number:  FP2100 
Features: 
-  cycle time:  1 ms 
Binary states in the drive can be output via the digital output. As result of the fast 
cycle time, it is possible to control external devices and to display the state in real 
time. In order that higher powers can also be output, the internal signal (TTL level) 
is amplified using a relay (refer to Fig. 3-23). 
Relay: 
-  max. opening / closing time:  5 / 10 ms 
  -  voltage / current  30 V DC / 5 A 
  250 V AC / 2 A

Fig. 3-23  Digital output 
The states, which are to be output, are defined using the "BI" parameter P0731 
(digital output). For the definition, the "BO" parameter number or "CO/BO" 
parameter number and the bit number of the particular state should be entered into 
P0731. Frequently used states including the parameter number and bit are shown 
in the following Table (refer to Table 3-11).
