Specifications for the step and direction inputs are as follows:

Applied Voltage
5 V maximum
Input Current
12 mA maximum
6.3 mA minimum
Step Pulse
500 nsec minimum pulse width
Setup Time
Direction input may change polarity coincident
with the last step pulse. The direction input must
be stable for 500 nsec before the drive receives
the first step pulse.
You can use an input voltage higher than 5V if you install a resistor in series with the input,
to limit current to the range specified above.
Encoder Input Connections
You must connect an encoder to the TQ10SD’s encoder inputs. These are differential
inputs; therefore, your encoder should have differential outputs. Single-ended operation is
possible, but is more susceptible to electrical noise and is not recommended. Up to 200 mA
at 5 volts is available from the TQ10SD to power encoder electronics.

on the encoder, which the
TQ10SD does not use. Do not connect these two wires to the drive.
