The SC control is flexible, cost effective way to implement compact mini systems for manual or automatic motion control.
It combines the popular OC2 control design with standard options and logic circuits.The SC series is available in three basic types:
BSC for forward operation without armature contactors
FSC for forward operation with one armature contactor
RSC for forward and reverse operation with two armature contactors and dynamic braking
Ratings:
1/8 – 1 HP
Input:115 VAC + 10%, 1Ø, 50/60Hz + 5%
Output: 0-90 VDC armature, 100VDC field
1/4 – 5 HP
Input: 230 VAC + 10%, 1Ø, 50/60Hz + 5%
Output: 0-180 VDC armature, 200VDC field
Overload Capacity: 150% for one minute
Acceleration: Adjustable from 0.5 to 15 seconds.
Torque (current) limit: Adjustable from 50 to 150% of rating.
Minimum speed: Adjustable from -5 to 10%
Maximum speed: Adjustable from 70 to 110%
IR Compensation: Adjustable from 0 to 10% boost.
FEATURES:
- Short circuit protection by sub-cycle line fuses.
- Independent, simultaneously operating torque and speed loops with sharp/smooth transition provide optimum speed regulation and precise torque limit cut-in regardless of speed setting.
- External torque limit program terminals can be used to set maximum torque in speed program mode or to program torque for tension control.
- Low level logic for options interfacing
- Screw type input-output connections
- Dynamic braking (standard on RSC, optional on FSC)
- Pushbutton start-stop operation
- Adjustable jog (optional)
- Automatic reversing (optional on RSC only)
- Multiple preset speeds (optional)
- NEMA 12 enclosure (optional)
- Speed meter (optional)
- Local operator station (optional)
- Remote operator Station (optional)
- Tachometer feedback (optional)
