P880 is used to normalize the speed which is obtained at the gearbox
output of the motor when a setpoint of 1000
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 rota-
tion, and setpoint:
S
Without inversion, the motor rotates clockwise for a positive setpoint
S
With inversion, the motor rotates anti–clockwise for a positive set-
point
Definition of the direction of rotation:
S
When viewing the output shaft, the shaft rotates counter–clockwise
! The motor direction of rotation is counter–clockwise
S
When viewing the output shaft, the shaft rotates clockwise
! The motor direction of rotation is clockwise
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.
The write from P40, the drive must be in closed–loop control, but with
the condition STW.4 = 0 (internal setpoint = 0).
At standstill, the speed controller gain (P17) is changed–over to P54
(P gain, speed controller standstill).
We recommend that the factory default setting of P54 = 2 remains
unchanged.
