Jumper
Description
Termination Encoder 2 Termination for encoder line receiver input 2. Encoder input
2 is related to motor axis 0. For differential encoder signals –
especially with longer cables and / or noisy environment it is
recommended to add jumpers for acitvation of line termina-
tion (120R resistor between each differential pair – A+ and A-,
B+ and B-, N+ and N-)

5.1 Encoder input termination
For enhanced reliability differential encoder signals should be terminated properly. The board offers
termination resistors (120 Ohm) for all three encoder interface signals (a/b/n) for all three encoders. By
setting jumpers, these resistors will be placed between the differential encoder signals. Do not set these
jumpers in case encoders with single ended signals are used.
Place jumpers for
proper termination

5.2 Enable all driver stages permanently
The /Shutdown input pin has to be connected to the supply voltage in order to enable the driver stages
for all three stepper motor axes. A jumper between pin 19 and pin 20 can be used to permanently enable
drivers.
