General Specification

The above parameters to be followed as minimum. Drive shall be supplied, considering the following

guidelines –

1. Drive shall be used to run an AC Squirrel Cage Induction Motor.

2. Application of this drive is to run a passenger ropeway, where system will start at full load (i.e.

100KW) and run at constant torque mode.

3. Drive shall be equipped with phase sequence monitor and any phase sequence shall be

acceptable to drive.

4. Drive shall be interlocked with other auxiliary loads, like motor air blower, gear box oil pump,

service brake, emergency brake, chain haulage and spacer.

5. Drive shall be run in following modes –

I. Normal full speed with ramp : 2.75 m/s

II. Maintenance Speed (approx 30% of full speed) with ramp : 0.60 m/s

III. Jog forward with ramp : 0.25 m/s

IV. Jog Reverse with ramp : 0.25 m/s

6. Positive and Negative ramp for different mode of run shall be adjustable. There shall be

following types of ramp –

I. +Ve 0-16 Sec (for normal and maintenance run)

II. +Ve 0-4 Sec (for Jog)

III. –Ve 0-16 Sec ( for normal stop in case of normal run and maintenance mode)

IV. –Ve 0-10 Sec (for Emergency Stop Type-I)

V. –Ve 0-6 Sec (For emergency Stop Type-II)

Ramp curve shall be selectable either linear or ‘S’ profile.

7. Drive should be capable to deliver minimum 150% torque at 1 Hz output

8. Drive shall keep its own memory with Lithium battery to keep set program. Drive shall be

programmable and the program shall be ready to copy and paste for future use. Drive shall be

able to store at least 16 previous faults in memory on FIFO sequence.

9. Drive shall be equipped with suitable memory card, to keep the program saved in case of

Lithium battery ageing or failure.

10. Drive shall have additional inbuilt following protections –

I. Lightning & surge protection

II. Heat sink temperature protection with Microcontroller monitored thermal sensor

III. IGBTs shall have soft recovery freewheeling diodes to prevent IGBT failure when

subjected to motor discharge spikes.

per IS: 694 and shall be 660 V / 1100 V with 99.97% pure electrolytic grade bright annealed

stranded bare copper conductors. Special parameters of HFLS/ZHFR PVC insulation like critical

oxygen index, temperature index, smoke density and flammability test shall conform to relevant

IEC and ASTM Standards.

All wires shall be colour coded as follows:

Phase Colour of wire

R Red

Y Yellow

B Blue

N Black

Earth Green (insulated)

Control Grey

19. Component selection shall be done as per ‘Type-2’ coordination.

20. Power Cable termination provision shall be made for incoming and outgoing cables.

21. All live parts shall be covered with transparent cover to avoid any unintentional touch

22. Drive panel shall be equipped with ventilation fan, to maintain drive performance at full load,

considering a room temperature as 300C.

23. Control power supply for drive reference shall be regulated.

24. All power electronics components of drive shall be suitably selected to withstand inverse

voltage.

Other Requirements –

1. Panel Supply, testing and commissioning shall be in scope of vendor

2. All internal components, wires, cables, etc shall be in scope of vendor.

3. Panel components shall be as per approved make, as per attached list.

4. 3 sets of Drive software and drawing shall be supplied along with panel. Drive applicable

software shall be of latest version. Update of the software shall be made available online or off

line free of charge till the drive useful life.

5. Panel testing shall be witnessed by company representative

6. Applicable commissioning spares shall be supplied along with drive.

7. Vendor shall furnish a list of recommended routine spares.

8. Drive and panel shall be guaranteed for a period of 1 year from drive commissioning.

9. All software work shall be in vendor scope. Parameters configuration, including graphics design

in mimic display also shall be in vendor scope.
