Parameter Descriptions 2-9
7000-TD002A-EN-P – September 2007
Slave2 Bridge Phase Angle [Slave2 Angle]
Linear Number: 617
Minimum Value: -360.0 deg
Maximum Value: 360.0 deg
Access Level: Service
Read/Write: Read Only
This parameter is the measured phase angle between the Master and the Slave 2 bridges and is
applicable for 18 SCR drives only. It should be close to +20 deg.
Harmonic Voltage [Harmonic Voltage]
Linear Number: 683
Minimum Value: 0.000 pu
Maximum Value: 32.767 pu
Access Level: Service
Read/Write: Read Only
This parameter represents the calculated value of the Harmonic Voltage on the input to the rectifier. The
firmware looks at the rectifier voltage and will measure the 5
th
harmonic voltage only. This value is
normalized to the rated line voltage, and will trip when the harmonic voltage exceeds the setting in the
parameter Harmonic VoltTrp (675) for the time specified in Harmonic VoltDly (676).
Common Mode Peak Current [ComModeCur Peak]
Linear Number: 779
Minimum Value: 0.00 A
Maximum Value: 655.35 A
Access Level: Service
Read/Write: Read Only
This parameter is for Direct-to-Drives only and displays the peak value of common mode current flowing
in the neutral resistor.
Peak Transient Volt [TransientVoltMax]
Linear Number: 778
Minimum Value: 0.000 pu
Maximum Value: 2.000 pu
Access Level: Service
Read/Write: Read Only
The peak capacitor voltage during the last bus transient is saved in the variable Peak Tran Volt #778.
Bus Transient Trip [BusTransient Trp]
Linear Number: 684
Minimum Value: 0.000 pu
Maximum Value: 32.767 pu
Access Level: Service
Read/Write: Read Only
This parameter shows the internal Bus Transient Trip value.
