Coolmay Launches C660 Series High-Performance Servo for High-Speed, High-Precision Automation
Coolmay has comprehensively upgraded its servo technology with the launch of the C660 Series High-Performance Servo. As automation equipment places ever-increasing demands on servo performance, the C660 Series is engineered for high-speed, high-precision automation applications. This shift is driven not only by higher customer expectations, but by the continuous improvement of production precision standards — which means servo performance directly affects positioning accuracy during long-term operation.
23-Bit Absolute Encoder for Precise Position Feedback
The C660 Series features a 23-bit high-precision absolute encoder that provides precise, real-time position feedback. Even during continuous high-speed operation, it helps minimize positioning deviation and drift, achieving a positioning accuracy of ≤5 arc-sec.
In modern automated production lines, even tiny positioning errors accumulate over long production cycles and can affect product quality, yield, and equipment lifespan. Reliable servo feedback is therefore essential for maintaining consistent performance in applications such as electronics assembly, CNC machinery, packaging, and robotics.
New-Generation Hardware Platform
A new-generation hardware platform increases CPU clock frequency by 2.4 times. Speed-loop response bandwidth reaches up to 3.5 kHz, delivering faster response and higher operating efficiency for demanding motion tasks.
FFT Multi-Point Notch Filter
To address vibration and speed fluctuations, the C660 Series is equipped with an FFT multi-point notch filter. This effectively suppresses mechanical resonance, allowing equipment to run more smoothly and stably.
EtherCAT Communication & Multi-Axis Synchronization
EtherCAT communication is supported, making the drive suitable for multi-axis synchronization. Standard RJ45 industrial Ethernet interfaces simplify wiring and troubleshooting, reducing commissioning time and maintenance effort.
Integrated Dynamic Braking
The C660 Series also integrates a dynamic braking function. In the event of an alarm or power failure, the motor can stop quickly and smoothly, reducing mechanical impact and potential equipment damage.
