Setting Quench mode

If, under certain circumstances, the modulation switches back on while the motor is still rotating fast,
this can result in a re-supply of the inverter's "overcurrent disconnection".
The quench modus is available to prevent this from happening ("quench" = synchronizing the rotating
magnetic field generated by the frequency inverter with the momentary speed of the triggered motor).
If this function is activated, the frequency inverter's rotating magnetic-field speed is synchronized with
the motor's field at the start of every triggering (nominal value and modulation must have been „0"
beforehand). Switchover into "normal mode" is automatic after the synchronization is completed.
Attention!
Due to the transient motor triggering with maximum frequency at reduced output voltage necessary for
the quench mode, short-term start-up can occur in a stationary motor with low centrifugal force.

Information
If quenching (quench mode = ON) is combined with the brake mode (DC brake mode = 1), quenching
is carried out initially and braking is only carried out in the event of a fault during the quench process.
If quenching is successful, braking is not carried out!

Boost function
ON: automatic voltage increase switched on (factory setting)
OFF: automatic voltage increase switched off

Quench mode
The quench function can be combined with motor braking (DC brake mode). However,
running both functions successively increases the time span until the motor is reaccel-
erated. For normal use, it is recommended to use only the quench mode.
Selection of function for Quench mode
ON = Ouench mode ON (factory setting)
OFF = Ouench mode OFF
