P0100 Acceleration time - Defines the time to linearly accelerate from 0 up to the maximum speed
(P0134)
- If set to 0.0 s, it means no acceleration ramp
0.0 to 999.0 s 20.0 s
P0101 Deceleration time - Defines the time to linearly decelerate from the maximum speed (P0134)
up to 0
- If set to 0.0 s, it means no deceleration ramp
0.0 to 999.0 s 20.0 s
P0133
Minimum speed - Defines the minimum and maximum values of the speed reference when
the drive is enabled
- These values are valid for any reference source

P0135 Max. output
current - Avoids motor stall under torque overload condition during the
acceleration or deceleration
- The factory default setting is for "Ramp Hold": if the motor current
exceeds the value set at P0135 during the acceleration or deceleration,
the motor speed will not be increased (acceleration) or decreased
(deceleration) anymore. When the motor current reaches a value below
the programmed in P0135, the motor speed is again increased or
decreased
- Other options for the current limitation are available. Refer to the CFW-11
programming manual

P0136
Manual torque
Boost - Operates in low speeds, modifying the output voltage x frequency curve
to keep the torque constant
- Compensates the voltage drop at the motor stator resistance. This function
operates in low speeds increasing the inverter output voltage to keep the
torque constant in the V/f mode
- The optimal setting is the smallest value of P0136 that allows the motor to
start satisfactorily. An excessive value will considerably increase the motor
current in low speeds, and may result in a fault (F048, F051, F071, F072,
F078 or F183) or alarm (A046, A047, A050 or A110) condition
