Introduction and Technical Data 23
Control Circuits: Fully isolated from po w er circuit.
Control Action: Advanced PI with fully adaptive current loops for optimum dynamic performance.
Self-Tuning Current Loop utilising " Autotune " algorithm.
Adjustable speed PI with integral defeat.
Speed Control: By Armature Voltage feedback with IR compensation.
By encoder feedback or analogue tachogenerator.
By a combination of encoder feedback and analogue tachogenerator or A VF.
Speed range 100 to 1 typical with tachogenerator feedback.
Steady State A ccuracy: 0.1 % Analogue Tachogenerator Feedback. (subject to tachogenerator)
2 % Armature Voltage Feedback
0.01 % Encoder only, Encoder + tacho, encoder + A VF – (With digital reference)
Protection: Interline device net works. High energy MOV'S.
Overcurrent (instantaneous). Overcurrent 150 % for 25s.
Field failure. Tacho failure. (With auto A V F back-up option).
Motor over-temperature. Thyristor Stack over-temperature.
Thyristor " Trigger" failure. Zero-speed detection.
Standstill logic. Stall protection.
