Cannot able to change the paramaeters of drive during running related to safty and motor in Siemens Sinamics G120 drives.
The parameter related to motor like motor voltage , rated speed and motor current can able to change after stopping the motor and setting quick ommissioning parameters.
However the parameters related to analog input / output can be changed even when the drive is in operation.
The procedure for quick commissiong of Sinamics G120 is as follows
The following parameters are necessary for quick commissioning (p0010 =1).
.
p0010 Drive commissioning parameter filter1
p0100 *) IEC/NEMA mot stds4 C(1)
p0205 Power unit application1 C(1)
p0230 Drive filter type, motor side3 C(1,2)
p0300 Motor type selection2 C(1,3)
p0301 Motor code number selection2 C(1,3)U
p0304 Rated motor voltage1 C(1,3)
p0305 Rated motor current1 C(1,3)
p0307 Rated motor power1 C(1,3)
p0308 Rated motor power factor1 C(1,3)
p0309 *) Rated motor efficiency1 C(1,3)
p0310 Rated motor frequency1 C(1,3)
p0311 Rated motor speed1 C(1,3)
p0314 Motor pole pair number3 C(1,3)
p0316 Motor torque constant3 C(1,3)UT
p0322 Maximum motor speed1 C(1,3)
p0323 Maximum motor current1 C(1,3)
p0335 Motor cooling type2 C(1,3)T
p0500 Technology application1 C(1,5)T
p0640 Current limit1 C(1,3)UT
p0700 Command source selection1 C(1)T
p0922 PROFIdrive telegram selection1 C(1)T
p1000 Selecting the speed setpoint
p1080 Minimum speed
p1082 Maximum speed
p1120 Ramp-function generator ramp-up time
p1121 Ramp-function generator ramp-down time
p1135 OFF3 ramp-down time
p1135 OFF3 ramp-down time
p1300 Open-loop/closed-loop control operating mode
p1500 Selecting the torque setpoint
p1900 Motor data identification and rotating
measurement
p3900 Completion of quick commissioning
At the end of the quick commissioning sequence, set p3900 =3 to carry out the necessary
motor calculations and clear all other parameters (not included in p0010 =1) to their default
settings.
When p0010 =1 is chosen, p0003 (user access level) can be used to select the parameters
to be accessed.
Only few parameters can changed during running conditions
IF you mean VFD most of drives NOT ALLOWED to change parameter during running like Seimens ,in Allen Bradly you can but its not recommended to change parameters during running cause of malfunction
for safety reasons we do not allow changing of important parameters in the drive to avoid any disturbances of the operation or something which may cause disruption or shutdown. If for any emergency means however there are some few parameters that can be change and is safe. However we make sure all these parameters are necessary or in need at large. If we can however wait for the right timing needless to adjust right away
The Parameters we can able to change, by disabling the Write Protection or by Advanced Level Access Password.....
IT is correct that in ABB/Siemens /Yaskawa/Allen Bradly drive/VFD/VVFD & most of the drive threre are2 types of parameters.1st type we con't change those are like drive application standards i.e SCALER( simple V/F,Siemens),VECTOR( Field oriented),DIRECT TORQUE Control( ABB).Ther are more parametrs you can't Change.
But in case of2n dType parameter you can change some parameter like Ramp UP Time /Ramp down Time.
But it is not recomanded to change any parameter change, which will affect the PID tuning of DRIVE TO Motor, because of that malfunctioning will occur.
In ABB ACS Drives if you change any parameter, it is recomanded to stop the drive, De-couple the Motor do ID Run & Save the Parameter for smooth & efficient operation.
The motor will stop because the PLC wont know what you wanted to do
