Kollmorgen S700 series digital servo amplifier

Kollmorgen S700 series digital servo amplifier

Basic Information

Core positioning: The S700 series is a high-performance digital servo amplifier that supports 208-480VAC three-phase input (S7xx0 model) or 110-230VAC single/three-phase input (S7xx6 model), integrates CANopen and EtherCAT bus interfaces, and comes standard with dual channel STO (Safe Torque Off) function (up to SIL CL3/PLe level). Additional functions such as PROFIBUS, SERCOS, DeviceNet can be achieved through expansion cards. It is recommended to use it with Kollmorgen motors and direct connection to loads is prohibited for operation.

Version and hardware adaptation: The document corresponds to hardware version 02.20 and requires firmware version ≥ 5.18 (ND1/NDO data structure). The functional differences between different hardware versions mainly lie in DC bus parallel capability and memory compatibility (support for memory cards at 02.10 and above). For older versions (such as 00.20/01.21), reference should be made to the corresponding manual revision.

（3） Optional configurations and expansion cards

Core Function Expansion

Security Expansion Card: Slot 3 can be installed with S3 (S1-2, SIL CL3/PLe) or S4 (S2-2, SIL CL2/PLd) security cards, supporting security functions such as SS1/SS2/SOS/SLS/SPLP. The S3 card also supports safety brake control (SBC) and brake testing (SBT).

Communication expansion card: Slot 1 supports PROFIBUS（DE-106712）、SERCOS（DE-90879）、DeviceNet（DE-103571）、SynqNet（DE-200073），Slot 2/3  Supports PosI/O (DE-200881) to expand high-precision I/O interfaces.

Feedback extension card: FB-2to1 (DE-201664) supports simultaneous connection of digital primary feedback and analog secondary feedback, solving compatibility issues with multiple feedback devices.

Heat dissipation optimization: Option F2 (Slot 2/3) is a controllable fan that automatically adjusts the speed based on temperature (55-75 ℃) and braking power (20-45W) to reduce noise (default fan noise is 43-65dB (A)).

Storage and Communication: Supports MMC/SD memory cards (DE-201257), which can store firmware and parameters, enabling fast configuration of multi axis systems; Standard RS232 (X6), CANopen (X6), EtherCAT (X7) interfaces, EtherCAT supports CAN over EtherCAT protocol and automatically detects bus type.
