Digital Input Servo Drive – Fast, Stable, and PLC-Compatible Motion Control
Tonghang servo drives with digital inputs are designed for high-performance motion control in automation systems requiring direct digital signal operation. They support multiple digital I/O channels, enabling precise control of start, stop, direction, alarm reset, and multi-speed modes via a PLC or external controller.
1. Digital Input Interface Function
DI/DO Control: The servo drive receives digital input signals (such as limit switches and enable signals) through interfaces such as CN1 and outputs status signals.
Signal Type: Supports 24V level input, with a high level range of 15-30V and a low level range of -3-5V. Typical leakage current is 6mA.
2. Application Scenarios
Home Return: Triggering an origin search through the DI terminal, combined with parameter settings, enables precise positioning.
Mode Switching: Switching control modes (such as position/speed mode) using digital inputs.
Our servo drives feature fast signal response and low-noise design, ensuring stable operation in CNC machine tools, packaging lines, textile equipment, and robotic systems.
As a professional OEM servo drive manufacturer, we offer customized digital input logic, PNP/NPN compatibility, and firmware optimization to meet your control system needs. Contact us today for detailed specifications, pricing, and OEM integration solutions for our digital input servo drives.
