INTRODUCTION Thank you for purchasing the T300MVi Medium Voltage ASD. This adjustable frequency, solid- state AC drive features a 3φ input isolation transformer with a 24-pulse converter design, a 32-bit CPU, and a three-unit power module inverter section providing a 5 level output for 4160/3300V drives and 3 level output for 2400V drives.
INITIAL COMMISSIONING CAUTION The drive should be commissioned by qualified personnel only. Below are some general steps required for commissioning. CAUTION Confirmation of Wiring Make the following final checks before applying power to the unit: 1) Confirm that source power is connected to terminals L1, L2, L3 (R, S, T). Connection of incoming source power to any other terminals will damage the drive.
CAUTION Cautions on Changing Setting Parameters The setting data of the T300MVi MV is saved in an EEPROM, non-volatile memory. When the micro controller initializes at power-up, it reads the EEPROM data and copies it to the RAM (Random Access Memory). From then on, the micro controller controls the drive using the values in the RAM. When the setting parameters are changed, by the display-keypad or personal computer ("support tool"), only the execution parameters in RAM are changed.
INSPECTIONS AND MAINTENANCE CAUTION DANGER Maintenance and inspection is a particularly effective means to help prevent failures and reduce down time. Creating equipment specific inspection and maintenance check sheets can help to perform maintenance and inspection effectively. Detailed inspections and regular maintenance should be carried out in short cycles initially until a schedule reflecting the site-specific conditions can be determined.
INSPECTIONS AND MAINTENANCE (cont’d) CAUTION Main Components 1) Cooling fan - Check to see if there is any abnormality with airflow, increased fan noise, etc. 2) Air filter - Visually check if the air filter is clogged. Gently tap it outside the room to remove loose dust.

INTERFACE The interface between the drive system and external devices is divided into two categories: power supply system and control system. Power Supply Interface and Ground The power supplies required are the main circuit input of 2400/4160V and (optional) control power supply of AC480V-60 Hz.
INTERFACE (cont’d) Motor Interface If armored and shielded cables are to be used, be sure to connect the shield drain or armor to the ground bus provided in the drive equipment near the motor terminals (U, V, W). Ensure that the motor is connected properly at the junction box and properly insulated to protect against accidental shorting or grounding.
INTERFACE (cont’d) Pulse Signal Output If a speed sensor is used, speed feedback signals can be output as pulse signals. The PG pulse output circuit is shown in the following figure. The power supply for the pulses should supplied from an outside source in a range of 12 V to 24 V.

INTERFACE (cont’d) Digital Output There are 6 programmable digital outputs (DO0-5). DO5 is used internally for control of the input contactor and should not be changed. The other 5 outputs are available for optional control or indication functions. These relays can be programmed to any bit in any word in the drive. The most commonly used bits can be found in the SSEQ_OUT1 and SSEQ_OUT2 words.
INTERFACE (cont’d) [Setting examples] • Example 1: When a 0~8V (0 to 100%) speed reference is input to AIN1. Set the input jumpers as per the drawings for single ended voltage input. Set a 0 to 100% (count 0 to 25000) speed reference signal at 0 to +8 V so that it is stored in SP_REF_AIN1. Input The input characteristic is shown in the right hand figure.
INTERFACE (cont’d) Additional Analog Outputs Six channels (D/A1 to D/A5 and Amp A) are provided as additional analog outputs. These outputs are wired out to terminal block TB-AO. Channel A is direct current feedback from the U phase Hall CT. The other five channels are programmable ±10vDC outputs.
CIRCUIT OPERATION Main Circuit Configuration The following circuit shows the configuration of the T300MVi 4160V drive. Input AC is supplied through an input controller to transformer T1. The transformer has four (4) isolated secondary windings per output phase, each feeding a 3-phase full wave rectifier bridge. The output of the rectifiers is connected to three inverter power modules that produce 3-phase AC power at the frequency and voltage required by the motor.
Page 54
CIRCUIT OPERATION (cont’d) The AC output voltage of the each inverter power module is 2400V line to neutral. With phase voltages shifted 120° from one other, an output voltage of 4160V between phases is generated. The output voltage closely approximates a sine wave. This is shown in the output waveform below. This produces a sine wave motor current with low distortion.
CIRCUIT OPERATION (cont’d) Control The following figure shows the T300MVi Vector Control block diagram. Vector Control Block Diagram D/q axis D/q axis Speed Torque Voltage Speed current current control reference control reference reference reference reference limit Tension ld/lq current detection control Speed detection (Option)
CIRCUIT OPERATION (cont’d) Speed Reference An external speed reference with count 25000/100% weighting is input by serial transmission or analog input and subjected to rate processing and limit processing to output an SP_R signal. The sign of the speed reference signal is "+" for normal rotation and "-" for reverse rotation. EXT=1 SEL_DI=1 25000 count/100%...
CIRCUIT OPERATION (cont’d) Speed Control The following figure shows the speed control block diagram. The speed reference signal SP_R and the filtered speed feedback are input and the deviation between these two is subjected to proportional/integral operations and output. After this signal is subjected to torque filtering and torque limit processing, a torque reference SFC_T_R is output.
CIRCUIT OPERATION (cont’d) Simulator Follower Control (SFC, optional control used with a speed sensor) When the machine has torsional resonance, the (SFC) function may be used to try to reduce the torsional vibration and increase the speed response. With SFC, the speed regulator output signal is input to an inertia compensation block. This block produces an estimated speed signal.
CIRCUIT OPERATION (cont’d) IQ Limit (Torque current limit) The IQ limit has a flat characteristic from 0 to base speed and tapers from base to top speed. The following settings are used to adjust the limits. LMT_IQ_BAS: Base speed torque current limit. Set 110%, 115%, etc. according to OL specification of the drive.
CIRCUIT OPERATION (cont’d) D-Q Axis Current Control The figure on the following page shows the block diagram of D-Q axis current control. This system controls the current of an induction motor by separating it into a magnetic flux (Field) component and a torque component. This drive controls the current on the D-Q coordinates. It can control the current to an AC motor as a DC value, achieving high performance control irrespective of output frequencies.
CIRCUIT OPERATION (cont’d) Output Voltage References (1) Output voltage references ED_R and EQ_R (the results of the current regulator) and the flux angle are input into a two to three phase conversion block. This block outputs the phase voltage references to the PWM (pulse width modulation) controller.
CIRCUIT OPERATION (cont’d) Speed Feedback (Option) As an option, a Resolver or a Pulse Generator (PG) can be selected for speed feedback. Speed control with a Tach Generator is not available because Tach Generator performance is poor. Resolver A resolver is an analog feedback device that used for speed feedback. Two sinewave excitation signals (sine and cosine) are sent to the resolver and two signals (sine and cosine) are returned to the drive.
CIRCUIT OPERATION (cont’d) Control Board Configuration The boards in the following table are used in the drive. The figure below shows the control board configuration. Boards Used Board Name Device Main function ARND-3110(*) Main control circuit ARND-3126B GSD3+ Gate signal distribution circuit ARND-8205(*) Optical gate signal circuit (electrical/optical signal conversion)
OPERATION The powering-on operation must follow a certain sequence. Failing to observe the powering-on sequence described here may cause unnecessary stress on the equipment. Be sure to observe the powering-on sequence. WARNING While the equipment is in operation and the motor is running, do not turn off the main circuit power supply or control power supply under any circumstances.
OPERATION (cont’d) Pre-Operation Check Points Check the following points before starting the operation. 1) Wiring is correct. 2) A voltage of 2400 V, or 4160 V, ±10% can be supplied as the input power supply voltage. 3) A voltage of 480 VAC ±10% can be supplied as the control power supply voltage. 4) The ground bus and any shielded wires are grounded.
