SC Series
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)
*
Voltage follower/isolator (optional)
*
Multiple preset speeds (optional)
* NEMA 12 enclosure (optional)
* Speed meter (optional)
* Local operator station (optional)
* Remote operator Station (optional)
* Tachometer feedback (optional)
