Description
LS-231SE 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 drive supports 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 separated. High resolution
encoders can be used for precise position control.
LS-231SE is equipped with various safety features
such as short circuit protection for the motor and the
drive, limit switch inputs, over/under voltage
shutdown and encoder presence control. Safety bus
can be connected for multi-drive system protection.
The maximum motor output current and overload
time can be set.
