Gullco GK-200-RL - Manual (Page 34)

GENERAL SPECIFICATIONS
The GSP-2100 microprocessor based motor control is a 24 vdc, full “H”-Bridge, pulse width
modulation control with regenerative braking. It is designed to run 24 vdc motors and requires a 24
to 38 vdc no-load supply (30 to 38 vdc is usually required for Gullco products to meet
specifications), usually derived form a full bridge rectified 22-24 vac source. The required wattage
of the supply depends upon the size of the motor. This control can operate any motor with a
capacity of up to 250 Watts (1/3 horse power).
The control can either operate with, or without, a closed loop tach feedback system attached to the
armature of the motor. A tach feedback is normally recommended as it allows the motor control to
constantly monitor and correct the speed of the motor providing accurate speed control regardless
of any variance in loading. A tach feedback system is also necessary for some automatic cycles to
function, or when using engineering units (counting of tach feedback pulses, used to measure the
distance travelled). Open loop (i.e. no tach feedback) may be acceptable for manual motor
operation in situations where; the motor sensor is temporarily damaged; the motor sensor is
susceptible to failure due to an exceptionally harsh environment; or where accurate calibrated
speed is not required and the loading of the motor is constant.
Various input and output ports are provided which are either optically coupled or transistor outputs.
These ports are described in detail later in this manual.
An L.E.D. display is provided to indicate the status of the control. This display is described in detail
later in this manual.
A varied selection of programs allows the control to behave in specific ways that are suited with the
motorized equipment and process that the controls are being applied to. Typically, each program
allows full manual operation of the motor and usually provides; automatic cycle routines;
programming ability for the operator to set and fine tune the automatic cycles to that desired; and
external interfacing. Refer to the manual for the specific product/micro-processor chip for details.
