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
