Output Circuit

SO1 SO2 Sequence output circuit

This comprises a Darlington driver with an open collector. This is connected to a relay or photo coupler.

There exists a collector-to-emitter voltage VCE(SAT) of approx. 1V at transistor ON, because of Darlington con- nection of the out put transistor. Note that normal TTLIC can't be directly connected since this does not meet VIL requirement.

This circuit has an independent emitter connection, or an emitter connection that is commonly used as the minus

(–) terminal (COM–) of the control power.

Calculate the value of R using the formula below so as the primary current of the photo coupler become approx. 10mA.

PO1 Line Driver (Differential Output) Output

Provides differential outputs of encoder signals (A, B and Z phases) that come from the scalar.

Receive these signals with a line receivers. In this case, install a resistor of approx. 330between the inputs.

These outputs are non-insulated signals.

Outputs Z-phase signals among those from the encoder. The outputs are non-insulated.

Receive these signal with high-speed photo coupler at controller side, since these Z-phase signal width is nor- mally narrow.
