Technical Instructions
1. Wiring Connections
The controller interfaces with an external driver via the following pins:
| Pin |
Function |
Connection to Driver |
| PUL |
Pulse signal |
PUL+ on driver |
| DIR |
Direction signal |
DIR+ on driver |
| EN |
Enable signal (optional) |
EN+ on driver |
| GND |
Common ground |
PUL-, DIR-, EN- on driver |
Note: Connect a 5–30 VDC power supply to the DC+ and DC- terminals of the controller.
Power Supply:
- Connect 5–30 VDC to DC+ and DC- terminals.
External Switches:
- Use Forward/Reverse/Stop pins with momentary switches for manual control.
2. Operation Modes
The ZK-SMC01 offers 9 preconfigured modes (selected via rotary encoder):
|
Mode
|
Description
|
|
F01→1
|
Manual rotation via encoder knob (speed/direction controlled by knob movement).
|
|
F01→2
|
Continuous rotation while CW/CCW button is pressed.
|
|
F01→3
|
Toggle rotation direction with CW/CCW buttons (speed set via F-03/F-05 parameters).
|
|
F01→4
|
Cycle mode: Motor completes set steps, delays, and repeats cycles (configurable via F-06).
|
|
F01→5
|
Return-to-origin mode: Motor moves forward, delays, returns, and repeats.
|
|
F01→9
|
Automatic back-and-forth motion with adjustable steps and delays.
|
3. Parameter Configuration
Adjust settings using the rotary encoder and LCD interface:
- Speed: Set via F-03 (forward) and F-05 (reverse).
- Steps: Configure F-02 (forward) and F-04 (reverse) for pulse counts.
- Delays: Program F-07 (forward delay) and F-08 (reverse delay).
- Cycles: Set F-06 for total repetition cycles.
Example Workflow:
- Press and hold the encoder to enter setup.
- Navigate to parameters (e.g., F-03) and adjust values using the encoder.
- Save settings (retained after power-off).
4. Safety & Compatibility Notes
- Driver Requirement: Use with a compatible stepper driver (e.g., DM542, TB6600). Ensure driver microstepping matches controller settings.
- Current Limitation: External driver must handle motor current (up to 4A for NEMA 17/23 motors)235.
- Overheating: Ensure adequate ventilation and avoid exceeding 60°C ambient temperature.
Applications
- CNC machines
- Automated packaging systems
- 3D printer axis control
- Laboratory automation
For advanced control (e.g., multi-axis coordination), pair with a PLC or microcontroller.
