Welcome to G-TV!
Today I would like to demonstrate how to do a basic start up and operation of an ABB ACS
355 AC Drive using a standard control pad.
After verifying that the wiring is correct, I can apply power to the drive to begin programming.
This particular drive has a standard control pad mounted to the front opposed to the advanced
control pad.
The standard control pad has a single LCD line display and is divided into five areas.
The upper left indicates the control location with either local or remote.
The center shows the value or parameter with the unit of this value displayed in the upper
right.
The lower left corner shows the panel operation state.
This could display output mode, parameter mode, main menu, or fault.
Finally the bottom right indicates the direction and status of the motor.
The soft keys below help navigate through the control pad and will be used in throughout
this set up guide.
There is also a local/remote key to allow an easy change to the control location and
a direction key to change direction of the motor.
To access the parameter menu, I will push the menu soft key.
The output on the bottom left should then change to menu.
I can then scroll with the arrows until I see PAR and push enter.
The menu and enter key are both the same and labeled on the standard control pad.
In the parameter menu the bottom left will now display PAR for parameter.
I will first go to parameter 9901 by using the arrow keys.
This parameter changes the language and can be adjusted by pushing the enter key for a
few seconds.
Since English is the default, I will keep this parameter without saving.
To do this, I will push the reset/exit soft key on the left.
The 99 parameter group is the start up data and will require the motor data found on the
nameplate located on the motor itself.
The next parameter is 9902, this sets the application macros.
This is application specific and should only be altered if required.
Some of these applications include PID control, 3-wire, potentiometer settings, and Modbus.
The next parameter is 9903 for motor type.
This can either be set for asynchronous motors or permanent magnet synchronous motors. 9904
sets the motor control mode for sensorless vector, vector, or scalar control mode.
For a basic start up, I will keep the 9903 and 9904 parameters at the default settings.
The 9905 parameter is for the motor nominal voltage, I’ll hold the enter button for
a few seconds to adjust the parameter.
The motor in this demonstration unit is approximately 460 Volts.
I’ll scroll to this value by holding down on the arrow keys and then push the enter
key to save.
Next I will arrow down to 9906 for the motor nominal current.
This should be listed in amps on the nameplate.
I will put in .8 for this motor, then hit enter to save.
Next I’ll go to parameter 9907 and I’ll enter the motor nominal frequency, which is
60.0Hz in this case.
Next I’ll go to parameter 9908 and enter the motor’s nominal speed.
My motor lists this as min minus 1,but many motors will list this in RPM.
The value on the nameplate is 1660.
Next I’ll go to parameter 9909 where I will enter the Motor Nominal Power.
This will be .25 horsepower according to the nameplate.
Some motors manufactured outside of the US will use kilowatts in place of horsepower
on the motor.
The values might be similar, but should not be taken as the same.
At this point I have completed the entry of my motor nameplate data.
If needed, I can change the acceleration and deceleration of the motor by going to parameter
2202 and 2203.
The default value is 5 seconds, which could be adjusted from anywhere from .1 to 1800
seconds.
Once I am finished with adjusting the parameters, I can push the EXIT key a few times to get
back to the output mode.
I’ll be sure to check that there are no faults or alarms shown on the display before
I start the motor.
Now I’ll Push the up arrow for my desired speed and then push the START button.
The bottom should flash FWD until it reaches the set point.
Once the desired speed is achieved the FWD will turn to a steady on.
By pushing on the arrow keys I can check the speed, current drawn, and the percentage of
torque the motor is producing.
I can push the direction button to switch direction of the motor.
The drive will ramp the motor down to zero speed, and reverse the motor direction.
The bottom right will display REV and the motor will then ramp back up to the commanded
speed.
To stop the motor I can push the stop key here.
