-
Setting this parameter to 1 saves the current parameter settings as "User default parameters". When the User carries out a 3-button
default parameter command (UP, DOWN and STOP), the parameters saved when P6-29 was last set to 1 will be restored, Setting “2”
clears user parameters.

A
For Geared (Induction) motors only: magnetizing / no load current, before Auto-tune, this value is approximated to 60% of motor
rated current (P1-08), assuming a motor power factor of 0.8. Note: For gearless PM motors this value must be 0.

Provides a pre-torque value (prior to brake release), normally used to improve Gearless motor rollback if P7-13 limit has been
reached, and also helps reduce noise as a result of rollback function. Also Active in Rescue mode.

P7-13
Rollback Control Gain
0.0
400.0
0.0
%
Sets the Rollback gain value (Active during P3-07 brake release time). Increase to solve rollback, too high a value can cause
instability/Vibrations/Over current trips, See section 13.3 for full details. Also Active in Rescue mode.
P7-14
Low frequency torque boost
0.0
100
0.0
Not used when P4-01 = 2, Primarily intended for PM Motors operating in open loop.
Allows a Boost current to be applied at start-up and low frequency (limit defined by P7-15), as a % of the motor rated current (P1-
08). Injecting some additional current into the motor at low speed to ensure that rotor alignment is maintained, and improving
operation during starting and low speed.
P7-15
Torque boost frequency limit
0.0
50.0
0.0
Hz
Frequency range for applied boost current (P7-14) as a % of motor rated frequency (P1-09). This sets the frequency cut-off point
above which boost current is no longer applied to the motor.

Sets the proportional gain value for the speed controller during rescue Mode operation.
Too high a value can cause instability or even over current trips.
