Drive Power Enabled Switch, Safety Mode
•
By means of an external switch the motor power supply can be interrupted.
•
In this case the valve enters the ‘safety mode’.
•
This motor interlock prevents the valve from moving (e.g. maintenance work).
•
Data reading from the control unit remains possible.
•
When motor interlock is active during power up, the valve directly enters the ‘safety mode’ and is
not able to do homing.
•
When ‘safety mode’ is entered from operation (i.e. pressure control mode), the unit will
automatically switch to safety control mode and remain at current position.
Once motor interlock is deactivated the valve go to control mode ‘Init’, so a homing is necessary
and will carried out depending on ‘Homing’ setting (Refer to ‘Power Up, Homing’)
For safety function without human risk it is recommend using interlock function of the
digital inputs, because no new homing is necessary after release of the interlock.
Refer to ‘Power connector IO’ >> ‘Digital Input’
