14-53 Fan Monitor

Option: Function:

Select the frequency converter

action if a fan fault is detected.

[0] Disabled

[1] * Warning

[2] Trip

14-55 Output Filter

Option: Function:

NOTICE

This parameter cannot be

adjusted while the motor is

running.

NOTICE

Reset the frequency converter

after selecting [2] Sine-Wave

Filter Fixed.

CAUTION

OVERHEATING OF

FREQUENCY CONVERTER

When using sine-wave lters,

there is a risk of overheating

of the frequency converter,

which can result in personal

injury and equipment damage.

Always set

parameter 14-55 Output Filter

to [2] Sine-wave xed when

using a sine-wave lter.

Select the type of output lter

connected.

[0] * No Filter This is the default setting and

should be used with dU/dt lters or

high frequency common mode (HF-

CM) lters.

[1] Sine-Wave

Filter

This setting is only for backwards

compatibility. It enables operation

when parameter 14-56 Capacitance

Output Filter and

parameter 14-57 Inductance Output

Filter are programmed with the

output lter capacitance and

inductance. It does not limit the

range of the switching frequency.

[2] Sine-Wave

Filter Fixed

This parameter sets a minimum

allowed limit to the switching

frequency and ensures that the

lter is operated within the safe

range of switching frequencies.

14-55 Output Filter

Option: Function:

Operation is possible with all

control principles. The modulation

pattern is set to SFAVM, which gives

the lowest acoustic noise in the

lter.

[ 1 - 1] Set the actual number of power

units.

4.13.6 14-6* Auto Derate

This group contains parameters for derating the frequency

converter if there is high temperature.

14-60 Function at Over Temperature

Option: Function:

If either heat sink or control card

temperature exceeds a factory-

programmed temperature limit, a

warning is activated. If the

temperature increases further, select

whether the frequency converter

should trip (trip lock) or derate the

output current.

[0] * Trip The frequency converter trips (trip

lock) and generates an alarm. Cycle

power to reset the alarm. The

motor restarts when the heat sink

temperature has dropped below

the alarm limit.

[1] Derate If the critical temperature is

exceeded, the output current is

reduced until the allowable

temperature has been reached.
