ABOUT THE SPYDER-PLUS-S1
The MAGPOWR Model Spyder-Plus-S1 (hereafter referred to as Spyder) is a microprocessor-based
control designed for precise closed loop control of either web tension, dancer position, or open loop
tension control proportional to a diameter input for unwinds and rewinds. The Spyder has a diameter input
to compensate for large roll builds in the dancer modes and provide for inertia compensation in
Load Cell
and
Dancer, Torque
modes.
The web tension control is capable of controlling web tension in unwind, rewind, or point-to-point
applications in any web press. The Spyder measures tension from one or more MAGPOWR load cells
and outputs a corrective analog signal to control a torque device. The tension setpoint for the Spyder is
set by an analog voltage signal or by a parameter from an Ethernet port. The Spyder provides an analog
input for Manual Level setpoint, control inputs for Run/Stop, Auto/Manual, Tension On/Off and E-Stop,
and a 0 1 mA or 0-10 VDC meter output proportional to measured tension. Inertia compensation during
stopping is available. Hold Level Output during Hold mode can be a fixed level, or vary with last running
output, or vary based on diameter and or tension.
The dancer control is capable of controlling a dancer in unwind or rewind applications in any dancer
system. The dancer control output can be connected to a torque device (brake or clutch), or a speed
device (motor). The Spyder measures the dancer position, using a MAGPOWR DFP potentiometer
connected to the dancer arm, and outputs a corrective analog signal to control a torque or speed device
that keeps the dancer position constant. The dancer setpoint for the Spyder is set by an analog voltage
signal or by a software setpoint which can be changed on the Spyder or from the Ethernet port. The
Spyder provides control inputs for Run/Stop, Tension On/Off, and E-Stop. The tension in the web is fixed
by the dancer loading. Additionally, load cells may be read while in Dancer mode and the 0-1 mA or 0-1
VDC meter output is proportional to measured tension. With
Diameter
selected in
Dancer
mode, the
diameter input is available to compensate for large roll builds. Inertia compensation during stopping is
available in Torque mode. In Torque mode, Hold Level Output during Hold mode can vary with last
running output, or vary based on diameter and or tension. In Speed mode, the output during Hold is
always zero.
The open loop tension control is capable of controlling the tension on an Unwind or Rewind based on an
analog diameter input including taper tension and inertia compensation during stopping. The tension
setpoint is set by an analog voltage signal or by a parameter from an Ethernet port. The control provides
an analog input for Manual Level setpoint, control inputs for Run/Stop, Auto/Manual, Tension On/Off and
E-Stop, and a 0-1 mA or 0-10 VDC meter output proportional to Diameter at Core divided by Present
Diameter to slow down Rewind motors to reduce clutch power dissipation.
The Spyder provides an Ethernet port for programming and data collection using either a web page or
Modbus/TCP.
