Digital frequency output / encoder emulation
The output signal of the Sub-D socket X8 can be used for superimposed control
circuits to feed back actual values (synchronous running, digital frequency
coupling or positioning control). Depending on the configuration under C005, it is
assigned as a digital frequency output or as an output for the encoder emulation.
Features:
( Two 5V complementary signals (TTL signal), electrically shifted by 90°
( Current capacity 20mA per channel
( Current capacity at PIN 8 (+5V): max. 5mA
The output signal is internally derived from the resolver or incremental encoder
signal.
