Q: Amp draw for I-Mark Controllers

I-Mark System Electrical Requirements & Circuit Recommendations
Overview
Proper electrical sizing is critical to ensure reliable performance of Columbia Marking Tools’ I-Mark controllers. While actual current draw varies based on axis count, motion load, and peripherals, the following guidelines provide safe, real-world circuit sizing recommendations.

These recommendations account for:

• Controller power supplies
  
• Servo/axis load under operation
  
• Cooling systems (fans, vortex, etc.)
  
• Startup/inrush conditions
  
• Allowable headroom for long-term reliability
  

Recommended Circuit Sizing

IM-200 Controller
Typical Configuration: 1–2 Axis Systems

• Recommended Circuit: 10 Amp (120VAC)
  
• Typical operating draw is lower, but this allows:
  
  • Startup surge capacity
    
  • Stable operation under load
    
  • Minor peripheral additions

IM-300 Controller
4-Axis System

• Recommended Circuit: 15 Amp (120VAC)
  
• Designed to support:
  
  • Multi-axis motion under load
    
  • Increased controller demand
    
  • Cooling systems and accessories
    
  
  

6-Axis System

• Recommended Circuit: 20 Amp (120VAC)
  
• Required for:
  
  • High-axis-count applications
    
  • Simultaneous motion loads
    
  • Additional I/O, tooling, and automation components
    
  
  

General Guidelines

• Always use a dedicated circuit for the marking system
  
• Avoid sharing power with:
  
  • Welders
    
  • Compressors
    
  • Large motors or inductive loads
    
  
  
• Maintain proper grounding for controller stability and marking consistency
  
• If additional equipment is tied into the system (feeders, conveyors, vision, etc.), consult CMT for final load verification
  

Notes on Actual Power Consumption
Actual amp draw will vary based on:

• Number of active axes
  
• Duty cycle and marking intensity
  
• Servo acceleration and load
  
• Cooling options (fans, vortex systems)
  

These recommendations are intentionally conservative to ensure:

• Reliable operation
  
• Reduced nuisance trips
  
• Long-term system performance
