Features:
- cycle time:
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:
- voltage / current

Fig. 3-23
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).
