P0100
Acceleration
Time
- It defines the time to accelerate linearly 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
- It defines the time to decelerate linearly 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
- They defines the minimum and the maximum values of the speed
reference when the drive is enabled
- These values are valid for any reference source

Current (V/f
control mode
current
limitation)
- It avoids motor stalling 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
- It operates in low speeds, modifying the output voltage x frequency
curve to keep the torque constant
- It 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 at low speeds, and may result in a fault
(F048, F051, F071, F072, F078 or F183) or alarm (A046, A047,
A050 or A110) condition
