PUL+
Pulse input
The default input voltage is 5V. For other
voltages, current limiting resistors must
be added, for example: 12V, external 1K
1 / 2W resistor, 24V, external 2K 1 / 2W
resistor.

Control Signal Wiring
If input control signal is differential, its control signal interface wiring diagram is shown
in Figure 2.
Fig.2 Control signal interface wiring diagram
If input control signal single-ended, its control signal interface wiring diagram is shown
in Figure 3:
Fig.3 Input interface circuit
Note: The default input voltage of the control signal is 5V. For other voltages, current
limiting resistors must be added. For example: 12V, external 1K 1 / 2W resistor; 24V,
external 2K 1 / 2W resistor.
Control signal timing diagram
In order to avoid some malfunctions and deviations, PUL, DIR and ENA should meet
certain requirements, as shown in the figure below:
Fig.4 Control signal timing diagram
Note:
1) t1: ENA (enable signal) should be confirmed to be high at least 100ms ahead of DIR,
to ensure that the brake is open, and the motor enters running state, to avoid
