Description
LS-231g3SB is all digital multifunctional single-axis
servo controller with integrated power amplifier
designed for applications requiring sinusoidal control
of Rotary or Linear brushless motors up to 1.5 HP.
DC (brush) and Voice coil motors are also supported.
In
LDCN
mode
the
coordinated motion of several motors. Up to 31
devices can be controlled over a multi-drop full duplex
RS-485 network. Standard RJ-45 connectors and
commercially available cables are used for daisy
chaining of the modules.
In Analog modes the drive supports precise speed
control. Analog modes give flexible use of Analog,
Enable and Direction inputs.
Three modes are provided in addition to the standard
Step & Direction mode. In Step Positive/Step
Negative mode the direction is controlled via two
separate step inputs. In Quadrature encoder modes
step and direction inputs can be connected to A and
B phase of an incremental encoder.
Dual-Loop encoder mode supports two encoder
inputs. In this mode the encoders for position and
servo
control are
encoders can be used for precise position control.
LS-231g3SB is equipped with various safety features
such as short circuit protection for the motor and the
drive,
limit
switch
shutdown and encoder presence control. Safety bus
can be connected for multi-drive system protection.
Maximum motor output current and overload time can
be set.
LS-231g3SB
supports
separated.
High resolution
inputs,

    (e.g. Start motion, Set Baud Rate, etc.). When a LS-231g3SB receives a command sent to its group address, it will execute the command but not send back a status packet.

When the Servo Drive enters its special path mode, it will automatically move from one point to the next at a user selectable rate in steps of 51.2 µSec.
  • Page 45 Because LS-231g3SB uses a fixed number of points per second, moving more slowly will result in a more accurate path than moving quickly. Also, a higher frequency path will be more accurate than a lower frequency path.
