8.5 Motor rotang direcon
In the default seng, both direcons of motor rotaon are enabled. Oponally, the direcon
of rotaon can be restricted so that only a clockwise rotaon (CW) of the motor is possible.
Precondions
Wiring of the motor phases must be carried out correctly with regard to the direcon of
motor rotaon.
In the documentaon and the parameter selecon texts, the following terms are used for the
direcon of rotaon:
•
Forward = clockwise direcon of rotaon (CW)
•
Reverse = counter-clockwise direcon of rotaon (CCW)
Details
The direcon of rotaon of the motor can be controlled in various ways:
•
Via the funcon "Reverse rotaonal direcon". Possible triggers to be selected for the
funcon "Reverse rotaonal direcon" are available for example in 0x2631:013 (P400.13)
the digital inputs and internal status signals of the inverter.
•
Via network. The denion of the direcon of rotaon is possible via the mappable Net-
WordIN1 data word or one of the predened process data words.
•
By specifying a bipolar setpoint value via analog input. Either via bipolar input range
(-10 ... +10 V) or conguraon of a bipolar seng range.
If a reversal is not required, the direcon of rotaon can be restricted in 0x283A (P304.00) to
"Only clockwise (CW) [0]".

Limitaon of rotaon
(Limit. rotaon)
Oponal restricon of the rotang direcon.
0 Only clockwise (CW) The motor can only be rotated clockwise (CW). The transfer of negave
frequency and PID setpoints to the motor control is prevented.
•
This funcon takes eect aer the "Reverse rotaonal direcon" func-
on (0x2631:013 (P400.13)).
•
Since this funcon only prevents negave setpoints, counter-clock-
wise rotaon (CCW) is possible if the motor has been wired for this
rotang direcon.

Assignment of a trigger for the "Reverse rotaonal direcon" funcon.
Trigger = TRUE: the setpoint specied is inverted (i. e. the sign is inver-
ted).
Trigger = FALSE: no acon / deacvate funcon again.
