The ramp times define how fast the pump may start up and shut down at the maximum when
the setpoint is changed.

1.6.4 Automatic PWM frequency reduction
1. "Additional settings"
2. "Automatic PWM frequency reduction"
The "Automatic PWM frequency reduction" function is switched off at the factory. If the
ambient temperature is too high, the pump will automatically reduce its hydraulic power
due to the too high temperature inside the drive. If this reduced hydraulic power leads to a
too low pump output for the application, it is possible to automatically reduce the PWM
frequency of the drive by switching it ON via this menu.
As a result, the pump automatically switches to a lower PWM frequency when a critical,
defined temperature in the drive is reached. By doing so, the required pump output is
achieved.
NOTICE
Due to the automatic PWM frequency reduction, the operating noise of
the pump can increase or change.
16 Diagnostics and measured val-
ues
In order to support fault analysis, the pump provides additional help apart from fault noti-
fications:
The Diagnostics help and the measured values are used for diagnosis and maintenance of
electronics and interfaces. Apart from hydraulic and electrical overviews, information about
interfaces and device information are provided.
