P0309 =...
P0309 =...
Rated motor efficiency
(Nominal motor efficiency in [%] from rating plate)
Setting 0 causes internal calculation of value.
P0100 = 0: P0309 no significance, no entry required.
P0310 =...
Rated motor frequency
(Nominal motor frequency in [Hz] from rating plate)
Pole pair number recalculated automatically if parameter is changed.
P0311 =...
Rated motor speed
(Nominal motor speed in [rpm] from rating plate)
Setting 0 causes internal calculation of value.
NOTE
For slip compensation, the input is absolutely necessary.
P0335 =...
Motor cooling
(Selects motor cooling system used)
0 Self-cooled: Using shaft mounted fan attached to motor
1 Force-cooled: Using separately powered cooling fan
P0640 =...
Motor overload factor
(Motor overload factor in [%] relative to P0305)
This defines the limit of the maximum output current as a % of the rated motor
current (P0305).

P1080 =...
Min. frequency
(enters the minimum motor frequency in Hz)
Sets minimum motor frequency at which motor will run irrespective of frequency
setpoint. The value set here is valid for both clockwise and anticlockwise rotation.
P1082 =...
Max. frequency
(enters the maximum motor frequency in Hz)
Sets maximum motor frequency at which motor will run irrespective of the
frequency setpoint. The value set here is valid for both clockwise and
anticlockwise rotation.
P1120 =...
Ramp-up time
(enters the ramp-up time in s)
Time taken for motor to accelerate from standstill up to maximum motor
frequency (P1082) when no rounding is used.
P1121 =...
Ramp-down time
(enters the deceleration time in s)
Time taken for motor to decelerate from maximum motor frequency (P1082) down
to standstill when no rounding is used
P1135 =...
OFF3 ramp-down time
(enters the fast stop ramp-down time in s)
Defines ramp-down time from maximum frequency to standstill for OFF3
command.
