The SSM line of integrated step-servo motors combines servo technology with an integrated motor to create a product with exceptional feature and broad capability.

FEATURES

  Multi-functional Capability

  Closed Loop

Very tight position and velocity control for the most demanding applications
Robust servo loops that tolerate wide fluctuation in load inertia and frictional loading
Precise positioning to within ±1 count using high resolution (20000 counts/rev) encoder

  Easy Tuning

- Pre-defined tuning parameters for
  maximum control performance and
  stability.
- Easy selection list provides the level of
  control desired.
- In most cases NO extra manual tuning
  is required.

  Lower Heating / High Efficiency

- Use only the current required by the
  application, generating minimum
  heat output.

- When stand-still, current can reach nearly
  zero for extremely low heat output.

- Being able to use almost 100% of torque,
  allows for more efficient and compact
  motor usage.

  Smooth & Accurate

- Space vector current control with 5000 line high resolution encoder, gives smooth and
  quiet operation, especially at low speeds.
  -> A feature never found with traditional stepper motors.

- High stiffness due to the nature of the stepper motor combined with the highly
  responsive servo control.
  -> Accurate position control both while running and static positioning

  Fast Response

When performing fast point-to-point moves,
the high torque output and advanced servo
control provide a very responsive system far
exceeding what can be done with a
conventional stepper system.

  High Torque

- Because the SSM operates in full servo mode,
  all the available torque of the motor can be
  used. The motor can provide as much as 50%
  more torque in many applications. High torque
  capability often eliminates the need for
  gear reduction.

- Boost torque capability can provide as much
  as 50% more torque for short, quick moves.

  High Speed

High speed operation typical of most servo systems is
possible because the SSM will not lose steps and stall out.

  Motion Monitoring

- For difficult control situations where
  performing a precise move is necessary, the
  SSM Quick Tuner tool provide an easy to use
  interface for performing and monitoring the
  motion profile.
- Many common parameters such as Actual
  Speed or Position Error can be monitored
  to evaluate system performance.
- The monitoring is interactive with the servo
  tuning capability so that optimum
  performance can be achieved.

SSM Quick Tuner Software

SSM Quick Tuner is the PC based software application used to configure, and perform
servo tuning, drive testing and evaluation of the SSM. System servo control gains, drive
functionality, and I/O configuration are set with Quick Tuner. It also contains an
oscilloscope function to help set the servo control gains.

System Wiring

MOONS' also offers two matched power
supplies for use with the SSM: A 24VDC, 150W
(P/N MF150A24AG-V) and a 48VDC 320W(P/N MF320A48AG-V).
These power supplies have current over load capability making
them ideal for use.
(To use with a switch power supplier, a RC050 regeneration
clamp must be connected in system)

Accessories

RC-050 Regeneration Clamp
The RC-050 regeneration clamp is for use where
regeneration from the motor may cause damage to the drive.
In these cases the RC-050 is connected between the drive
and power supply and absorbs regenerated energy.
