The ramps determine how quickly the motor can
accelerate and decelerate, during start-stop or
setpoint changes.
You can set the following:
• acceleration time, 0.1 to 300 seconds
• deceleration time, 0.1 to 300 seconds.
The times apply to the acceleration from 0 rpm to
fixed maximum speed and the deceleration from fixed
maximum speed to 0 rpm.
At short deceleration times, the deceleration of the
motor may depend on load and inertia as there is no
possibility of actively braking the motor.
If the power supply is switched off, the deceleration of
the motor only depends on load and inertia.

You can use this function to avoid condensation in
humid environments. When you set the function to
Active and the pump is in operating mode Stop, a
low AC voltage will be applied to the motor windings.
The voltage is not high enough to make the motor
rotate but ensures that sufficient heat is generated to
avoid condensation in the motor including the
electronic parts in the drive.
Remember to remove the drain plugs and
fit a cover over the motor.
