Main Characteristics - Fastech S-SERVOII Operating Manual

2. Main characteristics

1
No Step Out
(Alarm will be generated when step out)
Because of mounted encoder constantly monitor the
current position, step out cannot be occurred. If step out
occurred by external force of overloads, alarm signal will
be sent to upper controller. Thus, upper controller can
recognize step out of step motor.
2
Perfect Positioning Completion Check
(Positioning completion signal will be
generated)
When motor stops at the goal position, encoder detect
it and send positioning completion signal to upper
controller. Therefore S-SERVOⅡ resolve the problem of
unclear positioning of current Open Loop System.
3
High Position Accuracy
S-SERVOⅡ controls position by using high precision of
encoder. Regardless of motor type (2 Phase or 5 Phase),
S-SERVOⅡ position precision is only related to mounted
encoder resolution so high precision of positioning is
possible unlike open loop micro step motor and driver
which adapts 2 Phase or 5 Phase motor.
4
Heat Reduction / Energy Saving
(Motor Current Control according to load)
S-SERVOⅡ automatically controls motor current according
to load. S-SERVOⅡ reduces motor current when motor
load is low and increases motor current when load is
high. By optimizing the motor current, motor heat can
be minimized and energy can be saved.
