Control-Inputs INx
4 control inputs with HTL PNP characteristics are available on terminal 2
–
5 of X3.
Open control inputs are “low active”. The inputs could be used for control purposes. They could be
used for different functions regarding the parameterization.
Encoder Output A, /A, B, /B, Z, /Z
At the outputs of terminal X6, the encoder signals are available either in HTL or RS-422 format,
depending on the DIL switch S2/1 setting.
The output level corresponds in the HTL setting approximately to the supply voltage at X1.
(S2(1) = OFF, encoder output RS-422; S2(1) = ON, encoder output HTL)
Attention: If the DIL switch is set incorrectly, the following circuit may be
damaged.
Control Outputs OUTx
Two HTL (24V) signals are available at terminal 2 and 3 of X7. They can show different states
according to the parameterization.
At terminal 1 of X7, there is an analog test output which shows the status of the differential counter.
Here approx. 1.65V correspond to the counter value 0, the voltage range is max. 1.65V in both
directions and corresponds to approx. +/-128 increments. This output may only be connected to an
oscilloscope or a multimeter to record the timing behavior of the differential counter.
