PowerXL DG1 Series Adjustable Frequency Drives MN040004EN—March 2014 www.eaton.com 187
P21.1.14 632 Fan Control 1, 2, 3, 4 RW
This function allows you to control the PowerXL DG1’s cooling fan. You can set the
fan to run:
1 Continuous fan runs continuously
2 Temperature—based on the temperature of the unit. The fan is switched on
automatically when the heat sink temperature reaches 60°C. The fan receives a
stop command when the heat sink temperature falls to 55°C. The fan runs for
about a minute after receiving the stop command or switching on the power, as
well as after changing the value from “Continuous” to “Temperature”
3 First Start after power up, the fan is stopped until the run command is given and
then fan runs continuously. This is mainly made for common DC-bus systems to
prevent cooling fans to load charging resistors on power up moment
4 Calc Temp starting of cooling fan is based on calculated IGBT temperature.
When IGBT temp = 40°C, fan starts and when temp falls down to 30°C, fan
stops
Note: The fan runs continuously, regardless of this setting, when the frequency
converter is in RUN state.
P21.1.15 633 HMI ACK Timeout 1, 2, 3, 4 RW
This function allows the user to change the timeout of the HMI acknowledgement
time.
Example:
l Transfer delay between the frequency converter and the PC = 600 ms
l The value of HMI Acknowledge Timeout is set to 1200 ms (2 x 600, sending delay
l + receiving delay)
l The corresponding setting shall be entered in the [Misc]-part of the file
l NCDrive.ini:
l Retries = 5
l AckTimeOut = 1200
l TimeOut = 6000
It must also be considered that intervals shorter than the HMI Acknowledge Timeout
time cannot be used in frequency converter drive monitoring.
P21.1.16 634 HMI Retry Num 1, 2, 3, 4 RW
With this parameter you can set the number of times the drive will try to receive
acknowledgement when it has not been received within the acknowledgement time
(HMI Acknowledge Timeout) or if the received acknowledgement is faulty.
