2 direction signals:
The desired direction is set by using terminals RU (terminal 51) and RO (terminal 52):
RU RO Response
0 0 none or stop
0 1 up-travel
1 0 down-travel
1 1 none or stop
If a direction signal fails during the travel operation, the controller starts a deceleration ramp and
stops. A change of direction signals during the travel operation results in a direct change of the
required value sign up to a speed of 25 rpm. In the case of higher speeds, the change of direction
command is ignored for safety reasons and a warning message is signalled on the display.
5.2.2.2.4 Control via floating contacts, internal control voltage
5.2.2.2.5 Control via floating contacts, external control voltage
Important Note!
The positive potential of the 24 V supply voltage of the control unit and the VVVF controller must not
be connected to one another, only the reference potential ( ground ) may be the same.
