YKD2204M is high performance digital step driver based on YAKO’s new 32-bit DSP technology. It’s designed for various models of two phase 42mm (NEMA 17) hybrid stepper motors which current are below 2.2A. With servo-similar control circuit and superior software algorithm, YKD2204M has superior performance in smoothness, noise and vibration. Smooth and accurate current control technology greatly reduces motor heat.

Specifications:

• 32 bit DSP control technology, low noise/vibration with excellent stability and low cost
• 4 constant-torque microstep settings, 32 microsteps the highest
• Smooth and accurate current control, effectively reduce motor heats
• 100Kpps pulse response frequency
• After step pulse stops for 200ms, output current automatically halve to reduce motor heat
• Excellent smoothness in low frequency high microstep applications
• Photoelectric isolated signal input/output, high anti-interference ability
• Drive current adjustable (under 2.2A)
• Input voltage range: DC18~36V
• Fault protection: over voltage protection, low voltage protection, etc
• Small size: 86*55*21mm
• Weight: 120g

 

Power and Motor Connections:

Sr No.	Pin Name	Description
1	PWR	Power Indicator - When power on green led on
2	Alarm	Error Indicator - When over voltage, under voltage and over current red led on
3	PU	Connect with pulse photoelectric isolation negative head - Effects on falling edge, the motor moves one step as the pulse input change from high to low. built in resistance 384 ohm. Requirements: low level 0-0.5V, high level is the same as PU+, the pulse width>2.5us.
4	DR	Connect with direction photoelectric isolation negative head - Use to change motor directions. built in resistance 384 ohm. Requirements: low level 0-0.5V, high level is the same as DR+, the pulse width>2.5us.
5	+5V	Connect with signal power positive head - +3.3V-24V can drive, must add resistance to control current if the voltage is higher than +5V. No need to connect with resistance if the voltage is 3.3V and 5V, but 24V connects resistance 2K, 12V connects 820 ohm.
6	MF	Connect with signal power positive head - When effective low level (motor is free).  built in resistance 384 ohm. Requirements: low level 0-0.5V, high level is the same as PU+, the pulse width>2.5us.
7	+Vdc	18~36 VDC
8	GND	Gnd
9	A+	Motor Phase A+
10	A-	Motor Phase A-
11	B+	Motor Phase B+
12	B-	Motor Phase B-
