8.5 Motor rotang direcon
In the default seng, both direcons of motor rotaon are enabled. Oponally, the direcon
of rotaon can be restricted so that only a clockwise rotaon (CW) of the motor is possible.
Precondions
Wiring of the motor phases must be carried out correctly with regard to the direcon of
motor rotaon.
In the documentaon and the parameter selecon texts, the following terms are used for the
direcon of rotaon:
•
Forward = clockwise direcon of rotaon (CW)
•
Reverse = counter-clockwise direcon of rotaon (CCW)
Details
The direcon of rotaon of the motor can be controlled in various ways:
•
Via the funcon "Reverse rotaonal direcon". Possible triggers to be selected for the
funcon "Reverse rotaonal direcon" are available for example in 0x2631:013 (P400.13)
the digital inputs and internal status signals of the inverter.
•
Via network. The denion of the direcon of rotaon is possible via the mappable Net-
WordIN1 data word or one of the predened process data words.
•
By specifying a bipolar setpoint value via analog input. Either via bipolar input range
(-10 ... +10 V) or conguraon of a bipolar seng range.
If a reversal is not required, the direcon of rotaon can be restricted in 0x283A (P304.00) to
"Only clockwise (CW) [0]".

(Limit. rotaon)
Oponal restricon of the rotang direcon.
0 Only clockwise (CW) The motor can only be rotated clockwise (CW). The transfer of negave
frequency and PID setpoints to the motor control is prevented.
•
This funcon takes eect aer the "Reverse rotaonal direcon" func-
on (0x2631:013 (P400.13)).
•
Since this funcon only prevents negave setpoints, counter-clock-
wise rotaon (CCW) is possible if the motor has been wired for this
rotang direcon.

Assignment of a trigger for the "Reverse rotaonal direcon" funcon.
Trigger = TRUE: the setpoint specied is inverted (i. e. the sign is inver-
ted).
Trigger = FALSE: no acon / deacvate funcon again.
