3M2280N Step Motor Driver
9

The input circuits of all control signals of the driver have been reliably isolated through

optocoupler elements, which minimize the interference from external electrical noises.

In the figure, R0 is an external current limit resistor used to curb the input signal
current of the driver. When control signal is at 24VDC, a 2K resistor can be connected;
when the control signal is at 12VDC, a 1K resistor can be connected. The current at
the input port of the driver must be within 6~16 mA; otherwise, it may cause damage to
the equipment.

ERR signal is open collector output and requires an external power supply. The
maximum external voltage cannot exceed 30V. Never connect the ERR signal port in
reversed polarity; otherwise, it may cause damage to the port.

If driver work in a strong interference field,the control signal wiring is recommended
twisted-pair way,this can reduce the interference signal source interfere control
signal.
