Motor Terminals
Terminal No.
A+ / A-
B+ / B-
WARNING: Incorrect connection of phase winds will permanently damage the controller!
Resistance between leads of different phases is usually > 100KΩ. Resistance between
leads of the same phase is usually < 100Ω. It can simply measured by a multimeter.
Encoder Terminal
Terminal No.
+5V
GND
A
B
Z
WARNING: Except supply voltage port and motor terminal, voltage on port must be kept
between -0.3~5.3V. Otherwise, the controller will be damaged.
Attention:
If no special instructions, users use UIROBOT controllers must strictly follow the
specification that one controller can only drive one motor. Be careful to avoid connecting
more than one motor to the controller. The user should be responsible for the loss caused
by that error operation, our company will be not responsible for it.
