3.8 SP-## Special Functions

Parameter group for configuring special frequency
converter functions.
SP-00 Fault Level

Use this parameter to customise fault levels.
Option:
[0] Off
[1] Warning
[2] Trip
[3] Trip Lock

3.8.1 SP-1# Line On/Off
Parameters for configuring mains failure monitoring and
handling.

[1] Ctrl.
Decel
76
Function:
Use [0] Off with caution as it ignores all
warnings and alarms for the selected
source.
Changing a fault level from default option
[3] Trip Lock to [2] Trip leads to the
automatic reset of the alarm. For alarms
involving overcurrent, the frequency
converter has a hardware protection that
issues a 3-minute recovery after 2
consecutive overcurrent incidents, this
hardware protection cannot be overruled.
Alarm Off Warning

59 X
Function:
Select the function by which the frequency
converter must act when the threshold set in
parameter SP-11 Line Voltage at Input Fault has
been reached or a Mains Failure Inverse
command is activated via 1 of the digital inputs
(parameter group E-0#).
Only selections [0] No function, [3] Coasting, or
[6] Alarm are available when
parameter P-20 Motor Construction is set to [1]
PM, non-salient SPM.
The energy left in the capacitor bank is used to
run the motor, but is discharged.
The frequency converter performs a controlled
decel. Parameter B-10 Brake Function must be set
to [0] Off.
SP-10 Line failure
Option:
[3] Coasting
[4] Kinetic
back-up
[6] Alarm
NOTICE
For best performance of controlled decel and kinetic
back-up, set parameter H-43 Torque Characteristics to [0]
Compressor or [1] Variable Torque (no Energy Saving
should be active).

Illustration 3.32 Controlled Decel, Longer Mains Failure.
Decelling as long as the energy in the system allows for it,
then the motor coasts.
Illustration 3.33 Kinetic Back-up, Short Mains Failure.
Ride through as long as the energy in the system allows it.

Function:
The frequency converter turns off and the
capacitor bank backs up the control card, thus
ensuring a faster restart when mains reconnect
(at short power zags).
The frequency converter rides through by
controlling speed for generative operation of the
motor utilising the inertia moment of the system
as long as sufficient energy is present.
