SureServo2 Hardware Features
- Perfectly matched systems from 100W to 15kW:
- 8 systems accepting 120VAC single-phase input: 100W - 2kW
- 8 systems accepting 230VAC single-phase input: 100W - 2kW
- 14 systems accepting 230VAC three-phase input: 100W - 15kW
- 12 systems accepting 460VAC three-phase input: 400W - 15kW
- High bandwidth 3.1kHz for faster positioning, tighter control, and overall better performance.
- All motors come in brake and non-brake options
- Higher peak torque and larger intermittent duty zone per model (350% peak torque)
- High load inertia mismatch. Up to 50:1 or more depending on the application.
- Safe Torque Off (STO) validated by TUV. Allows drive power to be disconnected with a control level signal vs having to disconnect motor power with a large, expensive contactor
- Dynamic braking stops the motor when the motor is disabled, overloaded or when a fault occurs
- Regenerative braking is used during normal operation and can take advantage of a regen resistor (either built-in or external) to maximize deceleration
Newest Additions!
24-bit Absolute Encoder
16,777,216 Pulses Per Rev (PPR)...
...That's 46,603 pulses for ONE degree!
- SureServo2 supports any input resolution you desire (you don't have to supply 16M pulses for control)
- Internally, all motion is scaled to this high-resolution so that your application always benefits from this extreme accuracy
- Use battery backup to turn the encoder into an absolute encoder
- No loss of position, even if input power is disconnected
- Homing is not required on every power up sequence
Battery backup box enables absolute encoder functionality
Connections
SureServo2 is designed for easy hookup and configuration:
- Control and main power input on the top of the drive.
- The servo motor connects underneath.
- Two options for connecting your I/O:
- Choose the DIN-Rail mount breakout board to connect to ALL the I/O
- Or use the direct mount connector to access the most popular I/O points, AND to save space.
- Connect via USB for drive configuration with our FREE downloadable SureServo Pro2 software.
- Add an option card for EtherNet/IP or Modbus TCP to connect SureServo2 to your network

Safe Torque Off (STO)
SureServo2 systems support Safe Torque Off (STO). STO allows stopping all torque to the motor and eliminates the need for a large external contactor to disconnect the power circuit.
- STO immediately removes power (and thus torque) to the motor
- Keeps the other electronics "alive" for troubleshooting
- Compatible with most dual-channel safety relays
- Certified by TUV, the international safety standards organization
Professionally Manufactured Cable Sets
- For Motor, Encoder, & Brake (optional)
- Maintains IP rating of motor
- Standard or continuous flexing versions
- 3m, 5m, 10m, or 20m lengths
ZIPLink I/O Breakout Board
These accessories are required for interface to the on-board drive I/O (via the CN1 connector).
- Use the 50-pin DIN-rail mount terminal block to interface to ALL the drive I/O signals
- Choose from 3 cable lengths to locate the DIN-rail mount version
- Use the 20-pin, locally-mounted terminal block to connect the most common interface signals
Coupling Considerations
The SureServo2 motors have keyed shafts that are designed for use with keyed couplings or clamp-on or compression style couplings. Couplings using set screws should NOT be used with SureServo2 motors as they are likely to come loose or damage the motor shaft. "Servo grade" clamp-on or compression style couplings are usually the best choice when you consider the stiffness, torque rating, and inertia.
Higher stiffness (lb-in/radian) is needed for better response but there is a trade-off between the stiffness and the added inertia of the coupling. When sizing a coupling, the best practice is to use a safety factor of 1.3 to 1.5 over the SureServo2 peak torque requirement of your application.
Shop for Drive CouplingsMechanical Transmissions
Common mechanical transmissions include leadscrews, rack & pinion mechanisms, conveyors, gears, and timing belts. The use of leadscrew, rack & pinion, or conveyor are common ways to translate the rotary motion of the servo motor into linear motion of the load.
The use of a speed reducer such as a gearbox or timing belt can be very
beneficial for
these three reasons:
1. Reduction of Reflected Load Inertia
As a general rule, it is beneficial to keep the reflected load inertia as low as
possible while using the full range of servo speed. SureServo® systems can go up to 5,000 rpm
for the low inertia motors and up to 3,000 rpm for the medium inertia motors.
However, when investigating the effect of different speed reduction ratios DO NOT forget to include the added inertia of couplings, gearbox, or timing belt pulleys. These added inertias can be significant and can totally undo any inertia reduction due to the speed reduction.
2. Low Speed & High Torque Applications
If the application requires low speed and high torque, then it is common to introduce a speed reducer so that
the servo system can operate over more of the available speed range. This could also have the added benefit
of reducing the servo motor torque requirement which could allow you to use a smaller and lower cost servo system.
Additional benefits are also possible with reduction in reflected inertia, increased number of motor encoder counts at the load, and increased ability to reject load disturbances due to mechanical advantage of the speed reducer.
3. Space Limitations and Motor Orientation
Reducers can allow the use of a smaller motor or allow the motor to be repositioned. For example, some reducers
would allow for in-line, right angle, or parallel mounting of the motor.
