Introduction
1-1
Features
The SMARTSTEP A-series Servomotors and Servo Drivers have been developed as pulse string
input-type Position Controllers to replace stepping motors in simple positioning systems. The
SMARTSTEP A-series Servomotors and Servo Drivers combine the stepping motor’s ease of use
with faster positioning resulting from high speed and high torque, higher reliability with no loss of
positioning accuracy even during sudden load changes, and other advanced features.
■
Faster Response and Rotation Speed
SMARTSTEP A-series Servomotors and Servo Drivers incorporate the same high-speed and high-
torque features, unachievable with stepping motors, as the OMNUC W Series. The SMARTSTEP A-
series Servomotors provide faster rotation speeds of up to 4,500 r/min, with constant operation pos-
sible at this speed. Faster output torque of up to 1 s can output up to approximately 300% of the
rated torque, providing even faster middle- and long-stroke positioning.
■
Constant Accuracy
The A-series product line’s higher encoder resolution of 2,000 pulses/rotation provides feedback
control enabling continuous operation without loss of positioning accuracy, even with sudden load
changes or sudden acceleration or deceleration.
■
Minimal Setting with Servo Driver Front Panel Switches
The SMARTSTEP A Series can be operated immediately without time-consuming parameter setting.
The A-series Servo Drivers’ front panel switches enable easier alteration of function or positioning
resolution settings.
●
Resolution Settings
SMARTSTEP A-series Servomotor resolution can be selected from the following four levels:
500 pulses/rotation (0.72
°
/step); 1,000 pulses/rotation (0.36
°
/step) (default setting); 5,000 pulses/
rotation (0.072
°
/step); or 10,000 pulses/rotation (0.036
°
/step)
●
Command Pulse Input Setting
SMARTSTEP A-series command pulse input setting can be switched between CW/CCW (2-pulse)
and SIGN/PULS (single-pulse) methods to easily adapt to Position Controller output specifica-
tions.
●
Dynamic Brake Setting
SMARTSTEP A-series Servomotors can be forcibly decelerated to a stop at RUN OFF or when
an alarm occurs.
●
Gain Setting
A special rotary switch on SMARSTEP A-series Servo Drivers enables easy gain setting. Online
autotuning can also be activated with the flick of a switch, and responsiveness can be easily
matched to the machinery to be used.
