14.22 Ramps
The ramps determine how quickly the motor can accelerate and
decelerate, during start/stop or setpoint changes.
The following can be set:
• acceleration time, 0.1 to 300 s
• deceleration time, 0.1 to 300 s.
The times apply to the acceleration from 0 rpm to maximum
(fixed) speed and the deceleration from maximum (fixed) 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.

14.23 Standstill heating
You can use the 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 applied voltage is not high
enough to make the motor rotate but will ensure that sufficient
heat is generated to avoid condensation in the motor including
the electronic parts in the drive.

14.24 Motor bearing monitoring
You can set the motor bearing monitoring function to these
values:
• Active
• Not active
When the function is set to "Active", a counter in the controller will
start counting the mileage of the bearings.

14.25 Service
Time until next service (Motor bearing service)
This display shows when to replace the motor bearings. The
controller monitors the operating pattern of the motor and
calculates the period between bearing replacements.
Displayable values:
• in 2 years
• in 1 year
• in 6 months
• in 3 months
• in 1 month
• in 1 week
• Now
Bearing replacements
Indicates the number of bearing replacements that have been
done during the lifetime of the motor.
Bearings replaced (Motor bearing maintenance)
When the bearing monitoring function is active, the controller will
give a warning when the motor bearings are to be replaced.
When you have replaced the motor bearings, confirm this action
by pressing [Bearings replaced].
14.26 Number (Pump number)
A unique number can be allocated to the pump. This makes it
possible to distinguish between pumps in connection with bus
communication.

Note
The counter will continue counting even if the
function is changed to "Not active", but a warning will
not be given when it is time for replacement.
When the function is changed to "Active" again, the
accumulated mileage will again be used to calculate
the replacement time.
