1-1Overview
Overview of the SMARTSTEP 2 Series
The SMARTSTEP 2 Series is a series of pulse-string input type Servo Drives for position controlling
and it has been designed to function for low-capacity positioning systems. In spite of the compact
size, the SMARTSTEP 2 Series features realtime autotuning and adaptive filter functions that
automatically perform complicated gain adjustments. A notch filter can also be automatically set to
suppress machine vibration by reducing mechanical resonance during operation. The damping
control function of the SMARTSTEP 2 Series realizes stable stopping perf ormance in a mechanism
which vibrates because of the low rigidity of the load.
Features of the SMARTSTEP 2 Series
The SMARTSTEP 2 Series has the following features.
Compact AC Servo Drives
Compared to the SMARTSTEP A Series, the SMARTSTEP 2 Series can reduce the installation
space by 48% and the installation size by 39% in terms of volume. The AC Servo Drives of the
SMARTSTEP 2 Series are equipped with newly de veloped functions f or applications requiring more
precise positioning.
Suppressing Vibration of Low-rigidity Mechanisms during Acceleration/
Deceleration
The damping control function can suppress vibration of low-rigidity mechanisms or devices whose
ends tend to vibrate.
High-speed Positioning via Resonance Suppression Control
The realtime autotuning function automatically estimates the load inertia of the machine in realtime
and sets the optimal gain. The adaptive filter automatically suppresses vibration caused by
resonance.
Compatible with Command Pulse of 90° Phase Difference Inputs
In addition to conventional CW/CCW inputs (2 pulse inputs) and SIGN/PULS inputs (1 pulse input),
the SMARTSTEP 2 supports 90° phase difference inputs. This makes it possible to input encoder
output signals directly into the Servo Drive for simplified synchronization control.
A Wide Range of Pulse Setting Functions
A wide range of pulse setting functions, such as the command pulse multiplying, electronic gear,
and encoder dividing, enable you to perform pulse settings suitable for your device or system.
Simplified Speed Control with Internal Speed Settings
Four internal speed settings allow the speed to be easily switched by using external signals.
Encoder Dividing Output Function
The number of motor encoder pulses output by the Servo Drive can be freely set in the range of 1
to 2,500 pulses per rotation. A parameter can also be set to change the phase.

3-2 Servomotor Specifications
The following graphs show the characteristics with a 3-m standard cable and a 200-VAC input.
Temperature Characteristics of the Servomotor and Mechanical System
OMNUC G-Series Servomotors use rare earth magnets (neodymium-iron magnets).
The temperature coefficient for these magnets is approximately −0.13%/°C. As the temperature
drops, the Servomotor's maximum momentary torque increases, and as the temperature rises, the
Servomotor's maximum momentary torque decreases.
The maximum momentary torque rises by 4% at a normal temperature of 20°C compared to a
temperature of −10°C. Conversely, the maximum momentary torque decreases about 8% when
the magnet warms up to 80°C from the normal temperature of 20°C.
Generally, when the temperature drops in a mechanical system, the friction torque and the load
torque increase. For that reason, overloading may occur at low temperatures. In particular, in
systems that use a Decelerator, the load torque at low temperatures may be nearly twice as much
as the load torque at normal temperatures. Check whether overloading may occur at low
temperature startup. Also check to see whether abnormal Servomotor overheating or alarms occur
at high temperatures.
An increase in load friction torque seemingly increases load inertia. Therefore, even if the Servo
Drive gains are adjusted at a normal temperature, the Servomotor may not operate properly at low
temperatures. Check to see whether there is optimal operation even at low temperatures.

The drivable load inertia ratio (load inertia/rotor inertia) depends on the configuration and rigidity
of the machine being driven. Machines with high rigidity can be operated with a large load inertia.
Select the appropriate Servomotor and confirm the applicable load inertia.
Frequently operating a dynamic brake with a large load inertia may burn the dynamic brake
resistor. Do not turn ON/OFF the Servomotor frequently with the dynamic brake enabled.
