xx represents a change that affects hardware compatibility, yy represents a change that affects product documentation, and zz
represents a change that does not affect the documentation.
Unidrive SP Software Version
SPDrive.SoftwareVersion
The Unidrive SP software (or firmware) revisions are named using an xx.yy.zz format. xx.yy is displayed in parameter 11.29 of the
database, and zz is displayed in parameter 11.34. This parameter can be found on the Information tab on the Status view while
Online with PowerTools Pro.
xx represents a change that affects hardware compatibility, yy represents a change that affects product documentation, and zz
represents a change that does not affect the documentation.
Unidrive SP Encoder Revolution Counter
SPDriveEncRevCount
This read-only parameter displays the number of whole revolutions that the motor encoder signal has moved since powered up
(absolute) and can be found on the Online tabs on the Status and Position views. The units for this parameter are always revolutions
since those are the units used by the Unidrive SP and its’ option modules. The value for this parameter comes from parameter 3.28
of the database.
Unidrive SP Fine Encoder Position
SPDriveEncRevFinePosition
This read-only parameter displays the number of fractions of a revolution that the master encoder signal has moved, and can be
found on the Online tabs of the Status and Position views. The units for this parameter are always 1/(232) of a revolution since those
are the units used by the Unidrive SP and its’ option modules. The value for this parameter comes from parameter 3.30 of the
database.
Early releases of the SM-EZMotion module do not support use of high resolution encoders. Therefore, the value for this parameter
will always be displayed as 0.
Unidrive SP Encoder Position
SPDriveEncRevPosition
This read-only parameter displays the number of fractions of a revolution that the master encoder signal has moved, and can be
found on the Online tabs of the Status and Position views. The units for this parameter are always 1/(216) of a revolution since those
are the units used by the Unidrive SP and its’ option modules. The value for this parameter comes from parameter 3.29 of the
database.
Drive Status Bitmap
SPDriveStatus
The SPDriveStatus parameter is a decimal value that equates to the state of the Status Bits in the Unidrive SP. This is a read-only
parameter and is read directly from parameter 10.40 in the database. The individual bits in the bitmap are detailed below.
Bit 15 = Not Used Not Used
Bit 14 = Parameter 10.15 Mains Loss
Bit 13 = Parameter 10.14 Direction Running
Bit 12 = Parameter 10.13 Direction Commanded
Bit 11 = Parameter 10.12 Braking Resistor Alarm
Bit 10 = Parameter 10.11 Braking IGBT Active
Bit 9 = Parameter 10.10 Regenerating
Bit 8 = Parameter 10.09 Drive Output Is At Current Limit
Bit 7 = Parameter 10.08 Load Reached
Bit 6 = Parameter 10.07 Above Set Speed
Bit 5 = Parameter 10.06 At Speed
Bit 4 = Parameter 10.05 Below Set Speed
Bit 3 = Parameter 10.04 Running At Or Below Min Speed
Bit 2 = Parameter 10.03 Zero Speed
Bit 1 = Parameter 10.02 Drive Active
Bit 0 = Parameter 10.01 Drive Healthy
