Description
0606
Voltage at terminals 56.x/14.x
0611
Voltage at terminals 24.x/20.x
... indicates the analog voltage presently available at this input terminal.
0608
Inversion, terminal 56.x/14.x
0613
Inversion terminal 24.x/20.x
An inversion internally inverts the sign of the analog setpoint at this terminal. The motor direc-
tion of rotation is reversed.
0
No inversion
1
Inversion
There is the following assignment between inversion, direction of rotation, and setpoint:
S
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
0609
Smoothing time, terminal 56.x/14.x
(SRM, SLM)
0614
Smoothing time, terminal 24.x/20.x
(SRM, SLM)
This allows the output of the A/D converter to be smoothed using a PT
0610
Drift/offset correction terminal 56.x/14.x
0615
Drift/offset correction terminal 24.x/20.x
If the motor still continues to turn even with a speed setpoint of 0 V, and this is not desired, then
this parameter can be used to enter a voltage offset to adjust the analog input for zero output.
