Omron SMARTSTEP User manual

SMARTSTEP
easy to use, highly dynamic
A logical step
into basic servo solutions
Advanced Industrial Automation

Omron’s SmartStep is a combined (motor and driver) servo system for point-to-point (PTP)
positioning as part of a motion control process. SmartStep is designed to offer, in a simple way,
all of the performances of a servomotor while ens ring fast, high-torq e, high-precision
positioning. Its excellent servo performance, minim m start- p effort and very attractive price
make SmartStep the ideal sol tion for machine b ilders who need a basic, reliable servo
drive system for fast, precise positioning of their machines.
When reliability counts
Research has shown that Omron’s products are among the
most reliable on the market, and SmartStep is no exception.
Based on years of experience in motors and related
technologies, Omron’s SmartStep is designed to deliver
reliable, high-quality performance, around the clock.
ull range for all applications
here are two kinds of motor types – cylinder and flat.
here are six cylindrical motor types available, ranging from
30W to 750W outputs. he four flat motor models available
range from 100W to 750W. All SmartStep models conform to
CE, UL, cUL and other standards for international use.
Cost-effective servo solution

Easy to set up, easy to program
With SmartStep, easy-to-use dip-switches on the front panel
enable you to program basic parameter settings, including
auto-tuning, resolution setting, command pulse input setting,
and dynamic brake setting. he smoothness and
responsiveness of the motor is adjustable via the gain
adjustment switch.
Enhanced programming options
You can program the SmartStep with enhanced parameter
settings using Omron’s digital operator. his parameter unit
can be connected easily to the servo drive via a cable.
It can also be used to copy parameters from
one drive to another, enabling you to have
multiple drives in the same machine with
parameters at precisely the same settings.
In addition, Omron’s Wmon software package
can be used to program the servo drive, and
store the parameters in a PC.
Easy to connect
SmartStep is easy to commission via the pre-assembled
control cable, enabling SmartStep to be connected to an
external intelligence source like a PLC. Omron provides a wide
range of accessories for this called ‘relay units’. Furthermore,
SmartStep is easy to commission via the pre-assembled two-
in-one cable that handles both motor power and encoder
signal feedback.
Auto-tuning online
SmartStep’s auto-tuning function counteracts any vibration
caused by load variations, by adjusting settings automatically
and precisely to the machine movements.
The smart solution
SmartStep is the logical progression from
stepper motors to the servomotor world.
With SmartStep, the machine motor does not
lose position because the servo system has
positional closed-loop feedback, it is designed
to support big load ratio changes, and it is
faster and more precise, thanks to the
servomotor’s use of high encoder resolutions.

The right motor – every time!
Omron’s sizing software package (motor selection software)
calculates the ideal servomotor for your specific application,
so you’re never in doubt about which model to use for best
results. With this software you will be able to design your
machine, and the software will size your required SmartStep
servomotor.
In this application the machine fills a pouch with food,
medicine etc. here are two main movements to be
controlled; pulling the film (plastic etc.) and filling
the pouch.
Pulling the film
A servomotor will pull the film a certain quantity, pre-set
by the customer via the HMI.
he servomotor will start and stop at regular intervals and
these actions will be controlled by the PLC (via a digital
output) or by the advanced Motion Control Unit
(R88A-MCW151-E) together with the W Servo Family
(please contact Omron for further information).
illing the pouch
he SmartStep servomotor and the Omron PLC are used to
fill each pouch, and parameters like pulses, revolutions
and weight are set by the customer via the HMI.
he servomotor starts and stops at regular intervals and
these actions are controlled by the PLC (via a digital
output). he advantage of using the SmartStep is that the
online auto-tuning function will adjust the required gains in
the servo driver automatically for different kinds of difficult
products, such as sugar. Variations in temperature and
humidity can create differences between the set values and
actual values. In this case the customer can change the set
values via the HMI.
The HMI is responsible for:
he weight in each pouch
he ratio between pulses and weight
he speed of the servomotor
he start/stop ratio of the servomotor.

Compliant with international standards
Including CE, UL and cUL
In this application the machine sticks self-adhesive labels
to objects (like boxes and bottles) that pass through the
machine on a conveyor belt.
Sensor A reads the self-adhesive labels, and sensor B reads
the objects on the conveyor belt.
How it works:
he inverter controls the speed of the conveyor belt, while the
servomotor follows the speed of the belt. Once an object is
present on the belt the servomotor starts up, and stops when
the ‘label’ sensor detects that the labels are finished.
Via the HMI (Human Machine Interface) the customer can set
the speed ratio between the inverter (in this case the Master)
and the servomotor (slave) to speed up or slow down the
labelling process. he customer can also control the position
of the labels on the object by re-adjusting the timing/position
to the A and B sensor signals.
