SV660 Universal Servo Drive: 3kHz Bandwidth & 23bit Encoder for High-Precision Motion Control
SV660 Universal Servo Drive
High-performance AC servo drive with 3kHz bandwidth and 23-bit encoder for precision motion control applications.
Product Overview
The SV660 series servo is a high-performance, small-to-medium power AC servo product developed by INOVANCE. With a power range of 0.05kW to 7.5kW, this series supports multiple communication protocols including EtherCAT, Modbus, CANopen, CANlink and PROFINET. By adopting corresponding communication interfaces and working with a host computer, it enables networked operation of multiple servo drives.
Key Features
0.05kW-7.5kW power range for high-precision motion control of light to medium industrial loads
Multi-protocol support: EtherCAT/Modbus/CANopen/CANlink/PROFINET for seamless integration
Multi-drive networked operation with host computer for centralized control
Compact size with plug-and-play installation and fast wiring & debugging
Comprehensive protection functions with anti-interference design for harsh industrial environments
INOVANCE quality assurance with global compliance for industrial automation

Frequently Asked Questions
Q1: Can the SV660 work with my non-INOVANCE servo motor?
A: Yes, but it only supports AC permanent magnet synchronous motors with matching power and encoder type. You need to manually set motor parameters in the drive; auto-tuning may not work for non-original motors.
Q2: How do I switch communication protocols like EtherCAT and PROFINET on SV660?
A: Go to the drive's parameter menu, select the communication protocol option, choose your target protocol, then power cycle the drive. Don't forget to match the communication interface wiring and upper computer settings.
Q3: Why does the SV660 keep showing an overcurrent (OC) fault during startup?
A: Common reasons: ① Short circuit in motor cables; ② Overload from mechanical jamming; ③ Incorrect motor parameter configuration. Check wiring first, then reduce load speed and retry auto-tuning.
Q4: Can the SV660 operate in harsh environments (high temperature, dust)?
A: The drive's standard protection level is IP20, so it needs to be installed inside a closed electrical cabinet. Ensure cabinet temperature stays below 45°C and good ventilation; avoid direct dust or moisture contact.
Q5: What's the maximum number of SV660 drives I can connect in a network?
A: It depends on the protocol: EtherCAT/PROFINET can support up to 32 drives in one network segment (without signal repeaters). More drives require adding a repeater to avoid communication delays.
Q6: Do I need a separate braking resistor for the SV660?
A: Yes, for motors above 1.5kW, or if the equipment has frequent deceleration/heavy load braking. Without it, the drive will trigger an overvoltage (OV) fault and shut down.
Q7: How to solve the problem of SV660 positioning inaccuracy?
A: ① Check if the encoder cable is loose or shielded properly; ② Increase the position loop gain appropriately; ③ Verify that the mechanical transmission part (like gears, belts) has no backlash.
Q8: Is the SV660 compliant with EU safety standards?
A: Yes, it meets CE, RoHS standards, and has STO (SIL3) safety function. You can directly use it for equipment exported to EU markets.
