13.18 "Pulse flowmeter setup"
You can connect an external pulse flowmeter to one
of the digital inputs in order to register the actual and
accumulated flows. Based on this, you can also
calculate the specific energy.
To enable a pulse flowmeter, set one of the
digital-input functions to Accumulated flow and set
the pumped volume per pulse. See section
13.10 Digital inputs.
Factory setting
See section 30. Factory settings.
13.19 "Ramps"
The ramps determine how quickly the motor can
accelerate and decelerate, respectively, 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.

Factory setting

13.20 "Standstill heating"
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 is 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.
13.21 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 starts counting the mileage of the
bearings.
The counter continues counting even if the function
is changed to Not active, but a warning is not given
when it is time for replacement.
When the function is changed to "Active" again, the
accumulated mileage is again used to calculate the
replacement time.
