New Integrated Spindle Drives
with Absolute Multi-Turn Encoder
PRESS release: May 2021
- JVL A/S, one of the world’s leading producers in the field of integrated servo and stepper motors, is announcing a new addition to its ServoStep™ motors, a directly mountable motor for driving spindles. It’s perfect for replacing hand wheels in format change applications.
The new standard for setup axis
The new spindle drives are part of JVL’s series of motors with application focus. The spindle drives are based on the successful ServoStep™ series of integrated stepper motors. They are intelligent motors with the superior strength of the stepper technology with the controllability of a servo motor.
Heavy duty bearings
Superior speed control
On these new ServoStep™ family members, the motor shaft and bearing have been replaced with a hollow shaft mounted in an oversized double row bearing. Axial force is up to 7100 N. The hollow shaft has a clamp enabling direct mounting of a spindle.
The onboard SMC66 controller has a market leading resolution of 409600 counts/rev which makes the motor run smooth at any speed in increments of 0.01 RPM.
ServoStep™ has everything built-in including motor, encoder, drive electronics, control electronics with ePLC™ and optional Ethernet or CAN bus integrated into one compact unit. All major industrial Ethernet protocols like Profinet, EtherNet/IP, EtherCAT, SERCOS, ModbusTCP/UDP and Powerlink are available.
Options include: absolute multiturn encoders and STO (safe torque off, SIL3).
Also included are 8 I/O points which can be individually configured as digital input or output – or analogue input. The IOs can be used as local/remote IOs for the central PLC – or used together with the ePLC™ in stand-alone applications.
Ethernet switch for daisy-chain connection
You can choose between all major Ethernet protocols and due to the built-in Ethernet switch you can connect all your motors with just one cable running between them. Additionally, each motor can be equipped with an IO Junctions box for collecting sensor inputs or trigger outputs.
Function blocks (FB) for Siemens PLCs and Add-On-Instruction (AOI) for Rockwell Allen Bradley ControlLogix PLCs are available for download.
Daisy-chaining Ethernet (or CAN bus) cables
- All-in-one integrated unit – just add you own ball screw
- Double Ball Bearings enabling up to 7100 N axial load
- Torque-support pins can be fitted
- Closed-loop control
- Energy efficient due to automatic current control
- Built-in ePLC™ with 8 DIO, 24V or 0-5V (12bit) analog input with advanced filtering
- Ultra-high resolution: 409600 step/rev
- Speed-resolution down to ±0.01 RPM
- Change speed or torque or other parameters ”on-the-fly” (while driving)
- Option: Industrial Ethernet - support for all major protocols, Profinet, EtherNet/IP, SERCOS, EtherCAT, Powerlink and ModbusTCP/UDP
- Option: CANopen protocol with DS 301 and DSP 401 support. Double M12 connectors for easy daisy-chaining of the CAN bus
- Option: STO (safe torque off, SIL3)
