CANopen servo drive
Applied Motion Products expanded its SV200 servo drive offering with the release of drives designed for use in DC powered applications. They support CANopen.
Existing SV200 servo drives are designed for 120 VAC or 220 VAC operation, while the latest DC powered drives are designed to operate on 24 VDC, 48 VDC, or higher DC voltages (up to 60 VDC). For example, they are suitable for many machine builders and OEMs since they prefer DC supply voltages, especially when multiple axes are installed. Along with others, the product comes with a CANopen interface and CANopen control mode. Other control modes are analog, torque, velocity, positioning, Q programming, Ethernet, and Modbus. Other communication interfaces are for example EIA-232 and EIA-485.
With AC-powered drives, the AC to DC power conversion components are included in each drive, which allows for wiring directly to single or three-phase line voltages. However, these components add cost to the drives and when multiple axes are installed the additional costs can be prohibitive. DC-powered drives help alleviate this cost burden by consolidating power conversion components into as few power supplies as possible, allowing multiple servo axes to draw power from a single DC power source.
Removing the power conversion components from the drives also reduces their size, meaning DC powered drives take up less space in a control cabinet. Furthermore, their size of 16 cm x 11 cm x 5 cm makes these drives desirable for use in space-constrained applications such as automated guided vehicles (AGV).
DC-powered SV200 servo drives, beginning with “SV2D” in the part number, provide 10 A continuous and 20 A peak output current, allowing them to drive servo motors up to 80 mm in frame size and produce 550 W of continuous power. The drives are optimized for use with high torque J series of servo motors from the company. J series servo motors come in three frame sizes – 40 mm, 60 mm, and 80 mm – with windings optimized for DC supply voltages.
