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)
How do I set the microstep for the YKE2204M stepper drive?
The microstep settings are configured using the SW5 and SW6 switches. For instance, to set the default 200 PU/Rev, keep both SW5 and SW6 ON. For 1600 PU/Rev, set SW6 to ON and SW5 to OFF. Detailed combinations are provided in the Microstep Setting table.
What is the function of the SW4 switch?
The SW4 switch controls the current mode of the drive. Setting SW4 to the OFF position selects Half Current mode, while setting it to the ON position selects Full Current mode.
How do I adjust the Current RMS and Current Peak?
Current levels are configured using the SW1, SW2, and SW3 switches. You can set the RMS current from 0.2A (default) up to 1.6A (which corresponds to 0.3A to 2.2A Peak current) by following the ON/OFF switch combinations outlined in the Current Setting table.
What do the PWR and ALARM LED indicators mean?
The green PWR (Power) indicator lights up when the drive is powered on. The red ALARM (Fault) indicator lights up when the system detects a fault status, such as over current, under voltage, or over voltage conditions.
Do I need an external resistor for the control signal terminals?
The control signals support 3.3V-24V. However, if the control signal voltage exceeds 5V, you must add a current limiting resistor in series: connect a 2KΩ resistor for a 24V signal, or an 820Ω resistor for a 12V signal.
What are the power supply requirements for YKE2204M?
The drive requires a DC input voltage range of DC 18-36V, and the power supply output must be greater than 100W for stable operation.
