■ 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 |

■ Frequently Asked Questions (FAQ)
Q1:
How do I set the microstep resolution for the YKE2204M stepper drive?
You can configure the microstep resolution using switches SW5 and SW6. For example, for 16 microsteps (3200 PU/Rev), set SW6 to OFF and SW5 to ON. Refer to the Microstep Setting table for other configurations.
Q2:
What is the difference between setting SW4 to ON versus OFF?
Switch SW4 controls the standstill current setting. Setting SW4 to OFF configures the drive for Half Current mode, while setting SW4 to ON configures it for Full Current mode.
Q3:
How do I adjust the output current on the YKE2204M driver?
The output current is set using switches SW1, SW2, and SW3. Match the switch combinations to your motor's required Current RMS or Current Peak values as listed in the Current Setting table.
Q4:
What do the PWR and ALARM LED indicators mean?
The PWR (green) LED lights up to indicate that the drive is powered on. The ALARM (red) LED lights up to indicate a fault status, such as over-current, under-voltage, or over-voltage conditions.
Q5:
What voltage and power supply specifications does the YKE2204M require?
The driver requires a DC input voltage range of DC 18-36V. The recommended power supply rating should be greater than 100W.
Q6:
Do I need external resistors for the control signal inputs?
The control signals (PU, DR, MF) support 3.3V-24V. However, if the control signal voltage exceeds 5V, you must add an external current-limiting resistor: use a 2KΩ resistor for 24V inputs, and an 820Ω resistor for 12V inputs.
