Motor Rotating Direction - Lenze i55AE125B Manual

Motor control

Motor rotating direction

8.5 Motor rotating direction
In the default setting, both directions of motor rotation are enabled. Optionally, the direction
of rotation can be restricted so that only a clockwise rotation (CW) of the motor is possible.
Preconditions
Wiring of the motor phases must be carried out correctly with regard to the direction of
motor rotation.
In the documentation and the parameter selection texts, the following terms are used for the
direction of rotation:
Forward = clockwise direction of rotation (CW)
•
Reverse = counter-clockwise direction of rotation (CCW)
•
Details
The direction of rotation of the motor can be controlled in various ways:
Via the function "Reverse rotational direction". Possible triggers to be selected for the
•
function "Reverse rotational direction" are available for example in
the digital inputs and internal status signals of the inverter.
Via network. The definition of the direction of rotation is possible via the mappable Net-
•
WordIN1 data word or one of the predefined process data words.
By specifying a bipolar setpoint value via analog input. Either via bipolar input range
•
(-10 ... +10 V) or configuration of a bipolar setting range.
If a reversal is not required, the direction of rotation can be restricted in
"Only clockwise (CW) [0]".

Info
Optional restriction of the rotating direction.
The motor can only be rotated clockwise (CW). The transfer of negative
frequency and PID setpoints to the motor control is prevented.
• This function takes effect after the "Reverse rotational direction" func-
tion (0x2631:013 (P400.13)).
• Since this function only prevents negative setpoints, counter-clock-
wise rotation (CCW) is possible if the motor has been wired for this
rotating direction.
Both directions of motor rotation are enabled.
Assignment of a trigger for the "Reverse rotational direction" function.
Trigger = TRUE: the setpoint specified is inverted (i. e. the sign is inver-
ted).
Trigger = FALSE: no action / deactivate function again.
