1.4 Turntable control description
The turntable control is a DC motor control designed for the use as a turntable drive of
wrapping machines, where long and repeatable acceleration and deceleration times is
needed, and remotely selectable pre-set speeds are required. The unit requires a 90 V
armature, permanent magnet DC motor as output device.
CURRENT LIMIT
To protect the unit against damage, if the motor should stall, jam, or current demands
exceed the rating, a current-limiting circuit is included which keeps motor current at a
safe level regardless of motor load. The current limit is set at the factory and should not
require field adjustment.
CONNECTION
The motor armature attaches to quick disconnect terminals (+) (-) are accessible
through the faceplate of the plug-in module. The unit is suitable for permanent magnet
shunt style DC motors with 90 V armature rating, sized at up to 3/4HP.
1.5 Carriage control description
The carriage control is a DC motor control designed to operate in direct or reversing
mode at preset speeds defined by the user through the keyboard section. The unit
requires a 90 V armature, permanent magnet DC motor as output device.
Two relays and a dynamic braking resistor (DBR) are used for motor reversing and
braking. The brake resistor is bolted to a card-rack side plate, part of the MBIA. The
circuit is equipped with anti-plug protective interlocks.
CURRENT LIMIT
To protect the unit against damage, if the motor should stall, jam, or current demands
exceed the rating, a current-limiting circuit is included which keeps motor current at a
safe level regardless of motor load. The current limit is set at the factory and should not
require field adjustment.
CONNECTION
The motor armature attaches to quick-disconnect terminals (+) (-), on the MBIA
motherboard. The unit is suitable for permanent magnet shunt style DC motors with 90
V armature rating, sized at up to 3/4HP.
