Parameter Descriptions
2-171
7000-TD002A-EN-P – September 2007
DC Current Factor 7 pulse to 5 pulse [Idc Fac 7p to 5p]
Linear Number:
640
Default Value:
1.00
Minimum Value:
0.00
Maximum Value: 2.00
Access Level:
Service
Read/Write:
Read/Write
This parameter is used to modify the default level of dc current reference at which the rectifier will switch
from 7 pulse to 5 pulse operation. For normal drive operation, this parameter does not need to be
changed from the default of 1.00 pu because most drives can run in 7-pulse mode for the entire dc
current range. The purpose of this parameter is to reduce the amount of losses and heating in the
rectifier by reducing the switching pulse number.
Rectifier PWM Max Frequency [Rec PWM Max Freq]
Linear Number:
155
Default Value:
440 Hz
Minimum Value:
100 Hz
Maximum Value: 1000 Hz
Access Level:
Service
Read/Write:
Read/Write
This parameter is valid for PWM rectifier drives only and specifies the maximum switching frequency of
the power semiconductor devices.
Inverter PWM Max Frequency [Inv PWM Max Freq]
Linear Number:
154
Default Value:
440 Hz
Minimum Value:
100 Hz
Maximum Value: 1000 Hz
Access Level:
Service
Read/Write:
Read/Write
This parameter specifies the maximum switching frequency of the power semiconductor devices used in
the inverter.
Rectifier Device Gating Sequence A [Rec DvcGat SeqnA]
Linear Number:
620
Minimum Value:
0
Maximum Value: 65535
Access Level:
