Why Use SMC Controllers?

Major ReasonsMajor Reasons• Help minimize

downtime/ operating costs

• Help provide cost savings by minimizing the effects of – High inrush currents– High starting torque

SMC Helps Minimize Downtime/Operating Cost

• Problem:Problem:– Belts, gears and machinery can be damaged by across-the-line starting

• SMC Solution:SMC Solution: – Lengthens system life by reducing

mechanical stress during starting by using Soft Start– Helps eliminate the need for maintenance people to repair the process– No need to replace damaged parts– Minimal production loss

SMC Helps Minimize Downtime/Operating Cost

• Problem:Problem:– Materials can be

damaged by sudden starts and stops

• SMC Solution:SMC Solution:– Soft Start minimizes

damage by reducinghigh starting torque

– Soft Stop reduces damage by minimizing load shifting or spillage during stop

– Higher yield during production

SMC Provides Cost Savings by Minimizing Inrush Currents

• Problem:Problem:– Power company restrictions on incoming line

current, or you pay the penalty– Weak power lines cannot handle

high inrush currents, causing brown outs or excessive line disturbances, which in turn cause other processesto shut down

• SMC Solution:SMC Solution:– Current Limit starting minimizes the amount of

inrush current, meeting power company restrictions– Process shut down are minimized by reducing the

amount of current drawn during starting

SMC-3 Protection and Diagnostics

MotorMotor– Overload– Phase Reversal– Phase Loss/Open Load– Phase Imbalance

SMCSMC

– Overtemperature– Shorted SCR

Provides motor protection and minimizes the replacement costs of the motor

Provides internal diagnostic to aid in troubleshooting & SMC turns off when any of these faults occur, and LED

indicates fault condition

SMC-3 Protection and Diagnostics

• Phase Loss/Open LoadPhase Loss/Open Load– Helps prevent the primary cause of motor failure by

turning off the SMC when detected

• Phase ImbalancePhase Imbalance– Protects against motor heating due to imbalance in 3-

phase current

• Overtemperature Overtemperature – Protects against misapplication of SMC in incorrect

ambient temperature or excessive duty cycle

• Shorted SCRShorted SCR– Protects motor against single phasing when starting

SMC-3 Fault Indication

• Fault indication– LED for

indication• Number of

flashes for:– RUN/ON– FAULT – OFF
