3.6.2  Digital outputs (DOUT)  
Number: 3 
Parameter range:  r0730 – P0748 
Function chart number:  FP2100 
Features: 
-  cycle time:  1 ms 
Binary states in the drive can be output via the digital outputs. 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. 3-30). 
Relay: 
-  max. opening / closing time:  5 / 10 ms 
  -  voltage / current  30 V DC / 5 A 
  250 V AC / 2 A

Fig. 3-30  Digital outputs 
The states, which are to be output, are defined using the "BI" parameters P0731 
(digital output 1), P0732 (digital output 2) and P0733 (digital output 3). 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 – P0733. Frequently 
used states including the parameter number and bit are shown in the following 
Table (refer to Table 3-12).
