Setting parameters
Parameter Function Setting
P1082[0...2] Maximum frequency [Hz] This parameter sets maximum motor frequency at which
motor will run irrespective of the frequency setpoint.
Range: 0.00 ... 599.00 (factory default: 50.00)
P1120[0...2] Ramp-up time [s] This parameter sets the time taken for motor to accelerate
from standstill up to maximum motor frequency (P1082) when
no rounding is used.
Range: 0.00 ... 650.00 (factory default: 10.00)
P1121[0...2] Ramp-down time [s] This parameter sets the time taken for motor to decelerate
from maximum motor frequency (P1082) down to standstill
when no rounding is used.
Range: 0.00 ... 650.00 (factory default: 10.00)
Setting ramp-up / down rounding time
Rounding times are recommended, since they prevent an abrupt response, thus avoiding
detrimental effects on the mechanics.
Rounding times are not recommended when analog inputs are used, since they would result
in overshoot / undershoot in the inverter response.

P1131[0...2] Ramp-up final rounding time [s] This parameter defines rounding time at end of ramp-up.
Range: 0.00 ... 40.00 (factory default: 0.00)
P1132[0...2] Ramp-down initial rounding time [s] This parameter defines rounding time at start of ramp-down.
Range: 0.00 ... 40.00 (factory default: 0.00)
P1133[0...2] Ramp-down final rounding time [s] This parameter defines rounding time at end of ramp-down.
Range: 0.00 ... 40.00 (factory default: 0.00)
