Master frequency selection
For speed set value selection by means of a master frequency, the
9-pole SubD Dig.Set (X2) is used. As master frequency signal
either the simulated encoder signal of the master drive or an
incremental signal source with two TTL complementary signals
shifted by 90° el. can be used. The zero track of the master
endcoder will not be evaluated. The maximum input frequency is
300 kHz. The current consumption per channel is 6 mA.l.
