Parameter Descriptions 2-7
7000-TD002A-EN-P – September 2007
Master Bridge Line Voltage [Master Line Volt]
Linear Number: 136
Minimum Value: 0.000 pu
Maximum Value: 2.000 pu
Access Level: Service
Read/Write: Read Only
This parameter is the estimated value of the master bridge input voltage in per unit. This is calculated
from the measured rectifier input voltage and adding the voltage drop in the input impedance due to the
measured line current Master Line Cur (382). The Input Impedance (140) is determined by auto-tuning.
Slave 1 Bridge Line Voltage [Slave1 Line Volt]
Linear Number: 137
Minimum Value: 0.000 pu
Maximum Value: 2.000 pu
Access Level: Service
Read/Write: Read Only
This parameter is the estimated value of the slave 1 bridge input voltage in per unit. This parameter is
valid for 18 SCR drives only. This is calculated from the measured slave1 bridge voltage and adding the
voltage drop in the input impedance due to the measured line current Slave1 Line Cur (383). The Input
Impedance (140) is determined by auto-tuning.
Slave 2 Bridge Line Voltage [Slave2 Line Volt]
Linear Number: 138
Minimum Value: 0.000 pu
Maximum Value: 2.000 pu
Access Level: Service
Read/Write: Read Only
This parameter is the estimated value of the slave 2 bridge input voltage in per unit. This parameter is
valid for 18 SCR drives only. This is calculated from the measured slave2 bridge voltage and adding the
voltage drop in the input impedance due to the measured line current Slave2 Line Cur (384). The Input
Impedance (140) is determined by auto-tuning.
Master Bridge Line Current [Master Line Cur]
Linear Number: 382
Minimum Value: 0.000 pu
Maximum Value: 4.000 pu
Access Level: Service
Read/Write: Read Only
This parameter specifies the measured master bridge input current.
Slave 1 Bridge Line Current [Slave1 Line Cur]
Linear Number: 383
Minimum Value: 0.000 pu
Maximum Value: 4.000 pu
Access Level: Service
Read/Write: Read Only
This parameter specifies the measured slave1 bridge input current in per unit for 18-pulse drives.
