Terminal Introduction
| Symbol | Function | Specification |
|---|---|---|
| PWR | Power indicator | When power on, the green indicator lights up. |
| ALARM | Fault indicator | When over current, under voltage or over voltage, the red indicator lights up. |
| PU | Pulse signal photoelectric isolation - |
Effects on falling edge, the motor moves a step when the pulse goes from high to low. Built-in input resistance 384Ω, requirements: low level 0-0.5V, high level is the same as common anode, pulse width >5us |
| DR | Direction signal photoelectric isolation - |
Used to change motor direction. Built-in input resistance 384Ω, requirements: low level 0-0.5V, high level is the same as common anode, pulse width >5us |
| +(5V) | Control signal common anode + |
3.3V-24V can drive, the current limiting resistor must be added when voltage＞5V. Need to connect with resistor of 2KΩ when voltage is 24V, and connect with 820Ω when it's 12V |
| MF | Motor free signal optical isolation - |
When effective (low level), the motor coil current is turned off and the motor is free. Built-in input resistance 384Ω, requirements: low level 0-0.5V, high level is the same as common anode, pulse width >5us |
| -V | Power supply - | DC18-36V, DC input, power supply＞100W |

Q: How do I set the default microstep configuration for the YKE2204M?
By default, the microstep is set to 1 (200 PU/Rev). To configure this default setting, ensure that switches SW6 and SW5 are both set to the ON position.
Q: What is the function of switch SW4 on the stepper drive?
Switch SW4 controls the current mode. Setting SW4 to the OFF position activates Half Current mode, while setting SW4 to the ON position activates Full Current mode.
Q: How do I configure the current limit settings?
The current limits are set using switches SW1, SW2, and SW3. For example, the default setting of 0.2A RMS (0.3A Peak) requires all three switches (SW1, SW2, SW3) to be ON. Adjust the switch combinations according to the current table to match your motor's specifications.
Q: What do the PWR and ALARM LED indicators mean?
The green PWR indicator lights up when the device is successfully powered on. The red ALARM indicator lights up to signal a fault condition, such as over current, under voltage, or over voltage.
Q: What are the power supply requirements for the YKE2204M?
The drive requires a DC input voltage range of DC 18V to 36V, with a recommended power supply output capacity of greater than 100W.
Q: How does the MF (Motor Free) signal work?
The MF signal is an optically isolated input. When it is active (low level 0-0.5V), the drive turns off the motor coil current, releasing the motor shaft so it can be rotated freely by hand.
