Profile drive unit

Overview
The Modular Drive System is a configurable machine platform for programmable shape cutting, straight-line cutting/welding, stitch welding, programmable stitch welding, arc gouging, linear weaving, and pendulum weaving. The system is built around a Master Drive Unit that accepts interchangeable control modules to adapt the machine for specific cutting or welding tasks.

Master Drive Unit Description
The Master Drive Unit houses the motor, speed control board, power supply, and clutch for rapid manual carriage positioning. It operates at 2–120 in/min (51–3048 mm/min) with vertical load capacity of 60 lbs (27 kg) and horizontal load capacity of 100 lbs (45 kg). The unit features closed-loop speed and position control, a dedicated fail-safe brake with enhanced stopping and holding power, and motor overload protection which shuts down the motor and engages the brake under excessive load.

Control Modules

• Programmable Shape Module (MDS-1165) — Provides 2-axis, encoder-controlled, all-position custom shape motion; shapes and patterns built by segments. 2-axis motion provided by the Master Drive and the Linear Weaver with 40" crossarm.
• Straight Module (MDS-1002) — Direction and speed control for continuous cutting or welding applications.
• Stitch Module (MDS-1003) — Direction and speed control for continuous travel or Stitch Mode with adjustments for travel time, rapid time, and puddle build/crater fill times.
• Programmable Stitch Module (MDS-1004) — Provides programmable stitch controls for welding or cutting; program stitch by distance, automatic stop/return, independent timers for puddle buildup, with parameters set/displayed on a graphic screen for repeatable results.
• Arc Gouger Straight Module (AGS-1002) — Direction and speed control for arc gouging systems; interfaces to provide automatic travel when the arc is established.

Weaver Control Modules and Weaver Units

• Weaver Control Module (MDS-1005 / MDS-1005-DIAL) — Operates Pendulum or Linear Weaver and Master Drive Unit. Features include digital readout and control for longitudinal travel speed; Forward/Stop/Reverse switch; amplitude knob for weave width from 1/8"–2" (3–50 mm); weave speed up to 100 in/min (254 cm/min); left/right dwell controls; steering up to 2" (50 mm); weld contact and power On/Off. The MDS-1005-DIAL includes lockable numerical display dials for oscillator functions.
• Linear Weaver (WPD-1100) — Provides linear weave motion producing welds 1/8"–2" (3–50 mm) wide. Bolts to the front of the carriage; includes motor overload protection.
• Pendulum Weaver (WPD-2100) — Provides pendulum weaving motion useful for fillet welds in corner joints; bolts to the front of the carriage and uses a heavy-duty planetary gearbox for powerful output to the welding gun and attachments.

Features

• High torque, low inertia motor for precise starts and stops
• High-speed Linear/Pendulum Weaver with independent left/right dwell control
• High motor gearing to prevent cross-arm movement when powered off
• Closed-loop speed and position control for adjustable and repeatable welding parameters
• Quick clutch for rapid installation or replacement of weaver cross arm
• Gun-mounting group with adjustable racking for accurate gun positioning
• Contactor ON/OFF switch
