Hardware Settings (S5.7)

The Hardware Settings submenu (S5.7) provides parameters

for setting information on Internal brake resistor connection,

Fan control, Keypad acknowledge timeout, and Keypad

retries.

P5.7.1

Internal Brake

Resistor

Connection

Range: Connected–Not Connected Default: Connected

Internbrakeres

With this function, you tell the SVX9000/SPX9000 whether the internal brake resistor is connected or not.

If your drive has an internal brake resistor, the default value of this parameter is “Connected”. However, if it is necessary to increase

braking capacity by installing an external brake resistor, or if the internal brake resistor is disconnected, it is advisable to change the value

of this function to “Not Connected” in order to avoid unnecessary fault trips.

Note: The brake resistor is available as an option for all drives. It can be installed internally in frame sizes FR4 to FR6.

5.7.2

Fan Control

Range: Continuous, Temperature, First Start, and Calc Temp

Default: Continuous

Fan Control

This function allows you to control the SVX9000/SPX9000’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 heatsink temperature reaches

60°C. The fan receives a stop command when the heatsink 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 temperature = 40°C, fan starts and

when temperature falls down to 30°C, fan stops.

Note: The fan runs continuously, regardless of this setting, when the SVX9000/SPX9000 is in RUN state.

P5.7.3

Keypad

Acknowledge

Timeout

Range: 200–5,000

Units: ms

Default: 200

Keypad ACK timeout

This function allows the user to change the timeout of the keypad acknowledgement time.

Note: If the SVX9000/SPX9000 has been connected to a PC with a serial cable, the default values of Keypad Acknowledge Timeout and

Number of Retries to Receive Keypad Acknowledgement must not be changed.

If the SVX9000/SPX9000 has been connected to a PC via a modem and there is delay in transferring messages, the value of Keypad

Acknowledge Timeout must be set according to the delay as follows:

Example:

• Transfer delay between the SVX9000/SPX9000 and the PC is found to be 600 ms

• The value of Keypad Acknowledge Timeout is set to 1200 ms (2 x 600, sending delay + receiving delay)

• The corresponding setting is then entered in the [Misc] section of the file 9000XDrive.ini:

• Retries = 5

• AckTimeOut = 1200

• TimeOut = 5000

It must also be considered that intervals shorter than the Keypad Acknowledge Timeout time cannot be used in SVX9000/SPX9000 drive

monitoring.

P5.7.4

Number of

Retries to

Receive Keypad

Acknowledge-

ment

Range: 1–10 Default: 5

Keypad retry

With this parameter, you can set the number of times the drive will try to receive an acknowledgement when it has not been received within

the acknowledgement time (Keypad Acknowledge Timeout) or if the received acknowledgement is faulty.
