Menu PAR Description
22.11.2 3282 Maint.ST on
This parameter defines the value of the DC link voltage (Vdc threshold on figure) below which the MAINT. SOU-
STENS function starts. The default is Von = (√2 x Vmains) x 0.83.
Menu PAR Description
22.11.3 3284 Maint.ST off
This parameter defines the value of the DC Link over which the mains voltage is considered restored. Above this
value the drive stops managing the output frequency in order to maintain the value of the DC Link to Vdc setpoint
and restores the previous value before the power loss.
The default is Voff = (√2 x Vmains) x 0,92.
The Vdc setpoint value is calculated as (PAR 3282 + PAR 3284) / 2 (see figure).
This parameter works IPA when IPA 3286 Rehab.Maint.ST is set to (0) Automatique.
Menu PAR Description
22.11.4 3290 Retour Maint.ST
During the initial phase of the MAINT. SOUSTENS operation, this parameter allows to prevent the Sous tension
alarm by braking the motor with the purpose to increase DC link voltage.
When the DC link voltage drops below Vdc threshold, a frequency step reduction is applied, according to the result
of the following formula: (PAR 3290 + 1) x S, where:
- S is the asynchronous motor slip value
- PAR 3290 is automatically initialized according to the nameplate data of asynchronous motor.
Menu PAR Description
22.11.5 3292 Tps.Maintien.ST
This parameter defines the time between the interruption of the output frequency reduction and the generation of the
Sous tension alarm in case the mains voltage is not restored (Vdc < PAR 3284 Maint.ST off).
The behavior of the Sous tension alarm generated in this case is different compared to the normal Sous tension
alarm. In this case the alarm stops when the DC link exceeds the value of PAR 3284 Maint.ST off.
If the parameter PAR 4640 Redem soustension = (1) Validé, when the timeout expires UV Wng&Restart signal is
generated, in the same mode of the management of a normal Sous tension alarm. If the Sous tension alarm condition
ends within the time specified in the parameter PAR 4642 Redem soustension time, modulation is reactivated.
If the parameter value is zero no timeout is used.
Menu PAR Description
22.11.6 3294 Maintien.ST Kp
22.11.7 3296 Maintien.ST Ti
These parameters are the proportional and integral gains of the PI regulator that co
ntrol the output frequency in order to prevent that the drive goes in Sous tension.The PI input is the difference
between Vdc setpoint and the value of DC link and generates the frequency reference. The parameter values are
automatically calculated according to the motor data.
Menu PAR Description
22.11.8 3276 Reh.Maint.ST.Ext src
This parameter can be used to select the origin (source) of the Rehab.Maint.ST (PAR 3286) signal.
