GE IC800SSI104RS1-CE VersaMotion S2K controller

Heat Load and Cooling

The heat load of the S2K Series controllers is dependent on the model as shown below:

Stepper Controller

Model SSI105: Heat Load = 20 Watts + (0.3 * current setting in percent) or 50 watts max.

Servo Controllers

Model SSI104: Heat Load = 25 watts + (35 * duty cycle) watts or 60 watts max.

Model SSI107: Heat Load = 35 watts + (65 * duty cycle) watts or 100 watts max.

Model SSI216: Heat Load = 50 watts + (150 * duty cycle) watts or 200 watts max.

Model SSI228: Heat Load = 60 watts + (280 * duty cycle) watts or 340 watts max

Model SSI407: Heat Load = 35 watts + (65 * duty cycle) watts or 100 watts max..

Model SSI420: Heat Load = 60 watts + (250 * duty cycle) watts or 310 watts max.

Duty cycle is defined as the percent of time the controller is at full rated output divided by the

total cycle time. The SSI104 and SSI107 controllers are designed to operate at full rated

current with only natural convection cooling at ambient temperatures up to 50°C. The

SSD104, SSD107, SSI104, SSI107, SSI216, SSI228, SSI407, SSI420 and STI105 models

have built-in fan cooling.

The controllers must be installed vertically for effective cooling. Allow a minimum clearance of

3 inches above and below the unit. A minimum of 2 to 3 inches clearance is also

recommended on the right and left sides of the unit where possible.

Note: For UL approved installation of the following controllers, maximum ambient

temperature is 40°C (104°F): IC800SSI216P2, IC800SSI216RP2, IC800SSI216D2,

IC800SSI216RD2, IC800SSI228P2, IC800SSI228RP2, IC800SSI228D2,

IC800SSI228RD2, IC800SSI407RS1, IC800SSI407RP2, IC800SSI407RD2,

IC800SSI420RP2, IC800SSI420RD2

Stepper Controller Electrical Specifications

The S2K Stepper Controller (IC800STI105xx) is suitable for use on a circuit capable of

delivering not more than 5,000 rms symmetrical amperes and 130 volts maximum when

protected by RK5 class 15A fuses. Table 2-2 summarizes the Stepper Controllers

maximum continuous input power requirements. The actual input power and current is a

function of the motor's operating point and the duty cycle.
