Characteristics
Speeds, tensions, ratios, draws, limits, ranges, alarms, and other control
parameters can be set as percentages or exact numerical values. Parameters are
entered and displayed in common understandable units. The drive can be
completely setup prior to actual running and changes can be made during
operation. Keypad entry of changed parameters, protected memory, and factory
default values allow the operator to modify data with minimum risk to the
process.
The DSD is available for general use as a complete panel mounted enclosed
drive (NEMA 1 or NEMA 12).
Authorized system integrators can also purchase the drive as a power cube. The
power cube is designed for mounting in a cabinet; space allowances for air
circulation, additional components, outgoing terminals, and wire bends must be
provided.
The enclosed drive consists of the DSD power cube mounted on a panel with a
skirted NEMA 1 or NEMA 12 enclosure, with added fused control transformer
for 115V supply, armature loop contactor, and field wiring terminals. An input
circuit breaker with through-the-door operator is available as an option.
The DSD drive is designed to be connected to a three wire ungrounded power
system, or a four wire grounded or ungrounded power system.
All DSD drives are programmed using MagneTek's PAC language. The drive
programming consists of two portions; the standard control programs shared by
all DSD drives and the application specific programming which defines how the
drive operates in the particular application. The latter portion of DSD drive
programs are developed based on the PAC language, wherein different drive
functions are represented by interconnected graphical symbols, called PAC
blocks, much like an electronic schematic. This provides the ability to quickly
modify programs, along with an assurance of program repeatability and stability. PAC Language
