4.2.6.2 SinCos or ComCoder
If you are using SinCos or ComCoder as motor feedback, use the equations below to
determine the appropriate parameters for setup.
Kip
Kip = 2*PI()*2000*(motor line to line inductance)
Ex: l-l inductance = 0.018 H
Kip = 2*PI()*2000*(0.018)
Kip = 226 V/A
I2TF0
I2TF0 = 5/(2*PI()*(motor time constant in minutes)*60))
Ex: Mtc = 20 minutes
I2TF0 = 5/(2*PI()*20*60)
I2TF0 = 0..000663 Hz
I2TTrip
I2TTrip = (motor continuious current)*1.25
Ex: Ics = 4 Arms
I2TTrip = 4*1.25
I2TTrip = 5 Arms
ILmtPlus
ILmtPlus = (motor peak current)/(drive peak current)*100
Ex: Motor Ip = 4.5 Arms, Drive Ip = 9 Arms
Motor Ip = (4.5/9)*100
Motor Ip = 50%
ILmtMinus
Typically ILmtMinus is set to the same value as ILmtMPlus. Although there can be asymetrical
current limits in the drive.
Dpoles
Dpoles = motor poles
4.2.7 Save Options
There are three types of Save options. It is important to know how to use each type to ensure
that configurations are not lost.
Download NV - This button will save the parameter settings displayed in S200 Tools to the
selected drive. These parameters are saved to the drive's permanent memory and are recalled
during a power-up cycle.
Download Drive - This button will save the parameter settings displayed in S200 Tools to the
selected drive/node. However, unlike Download NV, these parameters are only saved to the
drive's temporary RAM and will not be recalled at a power-up cycle. It is recommended that you
use the Download Drive button when testing settings. Once you are satisfied with the settings,
click the Download NV button to permanently save the settings to the drive.
Save/Save As - You can also save the settings of a drive as a configuration file (*.S2C).
Remember, saving a configuration file does NOT save the settings to the drive. Configuration
files can be helpful for saving multiple drive setups. You can easily download a setting to a
drive by opening the configuration file in the Offline mode and clicking the Download NV/Drive
buttons once the proper drive is selected in the Online mode. It is recommended that you save
a configuration file for each setup.
