How to control the drive through the I/O interface
The table below describes how to operate the drive through the digital and analog
inputs when:
• the motor start-up is performed, and
• the default parameter settings of the Water default configurations are in use.
Preliminary settings
If you need to change the direction of rotation, check
that limits allow reverse direction: Check parameter
group 30 Limits and make sure that the minimum limit
has a negative value and the maximum limit has a
positive value.
Default settings only allow forward direction.Note that
efficient pump cleaning can require reverse speed.
Make sure that the control connections are wired
according to the connection diagram given for the
Water default.
See section Water default on page

Make sure that the drive is in external control. To
switch to external control, press key .
In external control, the panel display
shows text Auto at the top left.
