ELITE® Series
5 – 300 HP DC Motor Control, Regenerative and Non-Regenerative
General Description • Standard Features • Specifications • Model Ratings/Dimensions • Connections
Standard Features
- Programmable for operation from 230, 380 or 460 VAC 3 phase line input
- Insensitive to phase rotation of A.C. line input
- Full 10 ampere rated field supply with provisions for interfacing the Field Loss circuit to an external field supply or regulator
- Automatic Field Economy with customer adjustable “delay after stop” to reduce idling field voltage by 35%
- Current transformers for isolated armature current sensing
- Impedance isolation for armature voltage sensing
- Electrically isolated power modules rated at 1400 volts PIV and 1000 volts/microsecond DVDT
- Individual SCR R-C networks for transient protection
- Semiconductor line fuses for power circuit protection
- Thermostatically controlled fan (on forced ventilated models) to extend fan life
- Latching FAULT logic for safety shutdown with form “C” contact output and LED indicators for Phase Loss, Field Loss, Heatsink Overtemp and Overcurrent.
- 5 jumper selectable armature current ranges for each model to match motor rated armature current
- Timed Foldback current limiting and Overcurrent Trip with four programmable time periods of 15/75, 30/150, 45/225 and 60/300 seconds. The first number specifies time allowed at 150% before current “fold back” to 112% current. Second number specifies time of continued operation at 112% before Overcurrent Trip occurs.
- Independent control of positive and negative motor torque from external pot or voltage reference (negative torque on E12000 regen model only)
- Lockout of forward and reverse direction of motor rotation from external contact (reverse on E12000 regen models only)
|
- Independently adjustable linear acceleration and deceleration from 1 to 60 seconds for forward direction and reverse directions (reverse on E12000 regen models only)
- Speed feedback is jumper selectable for Armature Voltage, D.C. Tachometer voltage (7, 50 or 100 VDC/1000 RPM), A.C. Tachometer voltage (45 or 90 VAC/1000 RPM) or Digital Encoder (300 PPR)
- D.C. Tachometer voltage is insensitive to polarity
- 12 VDC @ 100mA rated power supply for encoder excitation
- Summing input for auxiliary input signals with on-board trim pot. for scaling and jumper selection for polarity
- Buffered armature current signal output
- Buffered velocity signal output
- Buffered velocity reference signal output
- Inner current loop type control circuit for responsive and precise control of motor speed and torque
- 115 VAC logic for customer operator interface
- Zero speed logic for controlled ramp-to-stop (braking torque supplied by E12000 regen models only)
- Jog Delay circuit to allow rapid jogging without de-energizing armature contactor to give longer contactor life
- LED indicators Run, Jog, Zero Speed and Foldback for monitoring operating status of the drive
- All important adjustment potentiometers mounted on de-pluggable “Personality Board” to allow Control board replacement while preserving setup parameters. Critical pots are multiturn and normal customer adjustments are single turn with a knob
- Multilevel construction with hinged cover and sub- panel allows ready access to all printed circuit boards, fuses and power components for ease of service and replacement
