2-174 Parameter Descriptions
7000-TD002A-EN-P – September 2007
Fan Configuration for Liquid-Cooled Drive Heat Exchangers [Fan Config]
Linear Number: 477
Default Value: 3 In-line
Access Level: Service
Read/Write: Read/Write
This parameter specifies the fan configuration for the heat exchanger used on PowerFlex Liquid-Cooled
drives. This parameter lets the drive know how many fans are installed, and their configuration. The
control can then properly turn the fans on and cool the system. The following are the available
configurations:
3 In-line 3 fans across the heat exchanger in series
4 Block 4 fans in a square configuration
4 Redundant 4 fans in a square configuration, but one is redundant
No Fans No fans (Liquid-to-Liquid heat exchanger)
Style #5 Reserved for Future Use
Coolant Temperature Warning [Coolant Temp Wrn]
Linear Number: 478
Default Value: 49 C
Minimum Value: 35 C
Maximum Value: 85 C
Access Level: Service
Read/Write: Read/Write
This parameter specifies the value of coolant temperature that will initiate a Coolant Temperature
warning. The temperature is measured from a thermistor in the cooling system.
Coolant Temperature Trip [Coolant Temp Trp]
Linear Number: 483
Default Value: 54 C
Minimum Value: 35 C
Maximum Value: 85 C
Access Level: Service
Read/Write: Read/Write
This parameter specifies the minimum value of coolant temperature that will initiate a Coolant
Temperature fault. The temperature is measured from a thermistor in the cooling system.
Pump Duty Cycle [Pump Duty Cycle]
Linear Number: 432
Default Value: 8 hrs
Minimum Value: 1 hrs
Maximum Value: 720 hrs
Access Level: Service
Read/Write: Read/Write
This parameter specifies the duty cycle for the pumps which circulate the liquid coolant.
