CANopen (C) and CANlink (A) variants also available
Safe Torque Off – SIL 3
1/3 ph 200 V, 3 ph 400 V
0.1 kW to 7.5 kW
Ultra-fast 4.5 kHz current loop
Feedback encoder interface: serial (Weton), Nikon and Tamagawa
Second encoder interface: incremental quadrature
+24 VDC backup control supply variant available
Control signals I/Os: 1x AI (12 bits), 1x AO, 8x DI, 5x DO
Speed loop bandwidt A speed loop response bandwidth of 3.2 kHz gives significantly improved performance compared to the previous generation of Inovance products.
Built-in USB-C port (for PC connection) and RS485 port (Modbus RTU communication protocol)
Drive’s control circuit can be supplied from the USB-C port, allowing an easy parameter upload/download and firmware upgrade, with no requirement to provide any additional power supply.
Position, speed, torque, compound control
– 16x multi-position registers for point-to-point and sequential motion
– Homing sequence
– Interrupt positioning
– Position comparison
Notch filter for mechanical resonance suppression
High resolution feedback encoder
23 bit serial single/multi-turn absolute encoder provides 8,388,608
pulses within one mechanical turn. Multi-turn absolute information can be also saved at power down, avoiding the need to perform machine homing at every power-up.
Functional safety – STO SIL3 EN/IEC 61800-5-2 compliant
The STO function guarantees safe machine stop without using additional contactors.
Short output winding Standard, built-in, short output winding ensures safe braking if the drive is unexpectedly disabled – even in the case of a failure in the motor holding brake.
Robust and reliable – designed for harsh environments
Isolated cooling channel prevents dust contamination of internal electrical components. Conformally coated PCBs are resistant to 3S2 and 3C3 environments (acc. to IEC 60721-3-3), providing further protection.
Enhanced functionality
Second encoder input (incremental quadrature type, differential signals) for full closed loop operation. Segregated control supply AC input in all ratings.
Easy installation and fast commissioning
Pluggable connectors for both signal and power allow avoidance of wiring mistakes. Fine tuning is possible using the STune and ETune software functions, which are both designed for use in applications with small load inertia changes:
– STune obtains the gains using a calculation based on the set stiffness level
– ETune automatically adjusts the optimal gain parameters of the servo drive to deliver the best performance
Easy cloning of drive parameters
Parameters of all SV670 drives in a machine can be cloned in one go
using the commissioning software
Guided PC commissioning with advanced software wizard
– Graphical User interface means specialist skills not needed for commissioning
– Software included free of charge
– Connect to a PC using standard USB-C cable
