Teco 7200MA VFD settings Help

[JohnTC]

I have a Teco 7200MA VFD 240v 50/60hz. HP: 3 KVA: 4. output 3ph 240v 9.6amp
the original spindle motor has died, I have decided to replace it with a water cooled spindle.
I have bought a Jianken JDG 80/2.2kw 220v 400hz 6A water cooled spindle
these are the VFD parameters sent with it
power: 2.2kw
max speed: 24000rpm
upper limit of the frequency: 400HZ
rated frequency: 400HZ
time of speed up / down: 20~30s

need help with the setup parameters any help would be greatly appreciated.

I have the user manual for the VFD but find it very confusing I would like to get it right first time rather than damage the spindle or VFD

Can you post a PDF of the manual I have some Teco VFD drive manuals but not that one yes you need more than just those parameters

here it is. thanks for taking time to help

This should get you going there may be some other Parameters to adjust or set

Teco 2.2Kw 400Hz 24000 RPM Spindle

BN-01=6 ( Acceleration Adjustable )

Bn-02=8 ( Deceleration Adjustable )

CN-02=400

CN-03=220

CN-04=400

CN-05=200

CN-06=110

CN-07=120

CN-08=66

CN-09=8

CN-10=50

CN-19=30

CN-25=110

CN-26=110

CN-34=4 ( Adjust up to 6 )

CN-45=2400

CN-46=02

SN-66=1 ( Auto Tune after all Parameters are set )

Many Thanks Mactec54

Im getting an PG parameter Error with the above settings
"Quote from manual"
Cn-45 and Cn-46 must meet the following relationship:
2 * Cn-45 * Cn-02 / Cn-46
?If not, an error message “Input Error” will be displayed

Your error is due to incorrect parameters.....the calculation the drive made with the parameters you were given is causing this error

[JohnTC]

thx for reply. yes I realise that. its the Cn-45 parameter that's the problem.

That's the spindle RPM

The CN46=2 for your 2 Pole motor

CN02=400 which is correct

So CN-46 has to match the spindle RPM 24000 I'm not sure if it can accept 24000

So CN-46=24000 Not 2400 should correct this

[mactec54]

Your error is due to incorrect parameters.....the calculation the drive made with the parameters you were given is causing this error

The parameters are correct unless you know better

CN-2=400
CN-46=2 number of Poles
CN-45=24000 spindle speed

CN-45=2400 missing a 0

Yes you posted it wrong

[JohnTC]

well I have a problem. the Cn-45 parameter range is 0000.1 ~ 3000.0 P/R. is there a work around.

He has given you the wrong parameter to set, Like I said earlier, instead just asking someone on the internet get the correct answers from either the dealer or the maker.

Can you solve the problem the parameters are correct as per the manual

[mactec54]

well I have a problem. the Cn-45 parameter range is 0000.1 ~ 3000.0 P/R. is there a work around.

Set it at the default of CN-45=0.0 and see what it does

I have contacted the makers first before posting and they haven't got back to me

Cn-45 parameter looks to be for encoder counts per revolution, I maybe wrong still learning

Is that what the book tells you? Looks as if its set up to give feedback for a rpm indicator.... If so that should be turned off. When I set up my Hitachi drive I only needed to change maybe 4 or 5 parameters, the rest I left at default. I just read through the manual to see which ones to change.

That's all you can come up with, read what I posted, ( This should get you going there may be some other Parameters to adjust or set )

Out of the PDF

(39) PG Parameter (Cn-45)
?The parameter is set in the unit of pulse/revolution. The factory setting is 0.1 P/R.
(40) Pole Number of Motor (Cn-46)
?Cn-45 and Cn-46 must meet the following relationship:

2 * Cn-45 * Cn-02
Cn-46
< 32767
?If not, an error message “Input Error” will be displayed

So Cn46 should be set at number of poles which is 2 try that. I did the calculation and it comes out 40 which is
< 32757
The factory setting for Cn45 should be 0.1
Cn 02 is Max Freq

Other than that, call the dealer in the morning and get the settings they want changed.

The factory setting for CN-45=0.0 not 0.1

CN-45 should be set to 0.0 he is not doing anything with that parameter if you set this Parameter you have to set other Parameters related to it

He already has CN-46 =2 and CN-02=400 check the Parameter list I posted
