Parameter Descriptions 2-125
7000-TD002A-EN-P – September 2007
Sync Xfer Option Parameters
Synchronizing Regulator Output [Sync Reg Output]
Linear Number: 298
Minimum Value: -10.00 Hz
Maximum Value: 10.00 Hz
Access Level: Advanced
Read/Write: Read Only
This parameter is the synchronizing regulator output, which is added to the speed regulator error during a
synchronous transfer from drive to bypass.
Synchronizing Regulator Error [Sync Reg Error]
Linear Number: 297
Minimum Value: -180.0 deg
Maximum Value: 180.0 deg
Access Level: Advanced
Read/Write: Read Only
This parameter is the synchronizing regulator error, which is the phase angle between the measured
bypass voltage and the motor voltage during a synchronous transfer from drive to bypass.
Bypass Voltage [Bypass Voltage]
Linear Number: 117
Minimum Value: 0.000 pu
Maximum Value: 2.000 pu
Access Level: Advanced
Read/Write: Read Only
This parameter specifies the voltage on the line-side of the Bypass Contactor, and is scaled in per unit
with respect to the Rated Motor Voltage.
Bypass Frequency [Bypass Frequency]
Linear Number: 159
Minimum Value: -100.0 Hz
Maximum Value: 100.0 Hz
Access Level: Advanced
Read/Write: Read Only
This parameter specifies the frequency of the voltage on the line-side of the Bypass Contactor.
Synchronizing Error Maximum [Sync Error Max]
Linear Number: 228
Default Value: 0 deg
Minimum Value: 0 deg
Maximum Value: 30 deg
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the maximum allowable synchronizing phase error. The bypass contactor will
be requested to close when the synchronizing phase error has remained below this maximum value for
the time specified by Sync Time (229).
