5.2 ”Speed setpoint” mode (P700 = 1) (from SW 2.0)
5.2.3 Direction of rotation reversal
5-128
P880 is used to normalize the speed which is obtained at the gearbox
output of the motor when a setpoint of 1000hex (4096dec) is entered
using control word STW.
If a negative value is entered into P880, then, in addition, the motor
direction of rotation is inverted.
There is the following assignment between inversion, direction of rotation,
and setpoint:
Without inversion, the motor rotates clockwise for a positive setpoint
With inversion, the motor rotates anti–clockwise for a positive setpoint
Definition of the direction of rotation:
When viewing the output shaft, the shaft rotates counter–clockwise
The motor direction of rotation is counter–clockwise
When viewing the output shaft, the shaft rotates clockwise
The motor direction of rotation is clockwise
5.2.4 Display of the position actual value
The position actual value can be set with P40 when commissioning the
system and so that the axis position can be tracked. P40 corresponds
with the settings of P1 to P4.
Note
The system does not go into the ”drive referenced” state when writing
into P40.
5.2.5 Adaptation of the speed controller
At standstill, the speed controller gain (P17) is changed–over to P54
(P gain, speed controller standstill).
