AC Drives - True Genius TG-600 Ac Drives - Victor G1000 & 2000
» Down |
INTRODUCTION :
VICTOR is a Microcomputer controlled General Purpose AC Drive (Inverter) with state-of-the -art electronics and incorporates the lastest semiconductor power device - Insulated Gate Bipolar Transistors (IGBT) and unique display unit consisting of 4 seven segment LED's and 16 x 2 character LCD's. VICTOR AC Drives are available in VICTOR G1000 and VICTOR G2000 Series.
The control circuity is centered around a 6 bit Microcontroller. The control method used is Specae Vector Modulation (SVM) in VICTOR G1000 and Sinusoidal Pulse Width Modulation with Flux Control in VICTOR G2000, which optimises utillisation of input voltage and facilitates smooth rotation of the Motor al low speeds.

FEATURES
» RAISE/ LOWER OPERATION
The output frequency setting can be increased or decreased through external potential free contacts. This feature eliminates the need of external reference units such as Satic reference unit, Motorised potentiometer.
» CURRENT LIMITING FUNCTION
VICTOR Drives are capable of limiting the output current to a pre-set level ensuring continuous operation of the Drive without tripping, espacially during acceleration.
» THREE WIRE OPERATION
This feature allows to control run or stop operation by means of one pulse command eliminating additioal external relay circuit.
» CATCH ON FLY
In high inertia loads, during power resumption after failure, Inverter will catch on from the frequency corresponding to the actual motor speed and accelerates to the reference speed.
» FAULT MEMORY
Upto 19 previous faults are stored on first out order and can be viewed in the same order. This facilitates ease of trouble shooting. |
» DC INJECTION BRAKING
This function is used to decrease the stop time and to improve the stop position accuracy. The frequency at which DC injection braking starts, braking voltage and braking time can be programmed.
» EIGHT STOP SPEED CONTROL
Multi-step speed operation can be realised by turning on and off with three external potential free contacts and a miximum of eight different speeds can be programmed.
» ELECTRONIC THERMAL OVERLOAD RELAY
The Drive will trip considering the Motor cooling characteristics at low speed (inverse time characteristics).
» SLIP COMPENSATION
This function corrects the AC Drive output frequency based on load current to compensate the slip of the AC Motor and the resulting accurancy can be 1% of base speed.
» MULTI ACCELERATION/DECELERATION TIME
This function enables to program four different acceleration or deceleration time realised through two digital inputs.
