Lenze 8600 series - Features of Setpoint; Offset and Gain Adjustment

Features of setpoint 2
Setpoint 2 tan only be provided via the differential input
Xl/terminals 1,2, independently of the selected operating mode
(Cool). Its value tan only be displayed in per cent under code
co49.
Setpoint 2 is processed first by a special ramp generator, before it
is added to setpoint 1 .The ramp times of the ramp generator are
set separately via C220 and C221.

In the factory-set configuration CO05 = -0-, setpoint 2 is not active.
If you want to use setpoint 2, e.g. as additional setpoint, you have
to select another configuration and to set the gain of the setpoint
channel correspondingly.
Please also note that setpoint 2 is set to zero as long as a JOG
frequency is active.
In the configurations with dancer-Position controller a diameter
Sensor is connected to the differente input Xi / terminals. 1, 2.

Offset and gain adjustment
Using these functions you tan eliminate undesired distortions of the
analog input channels and adapt the connected encoder.
Offset
To compensate offset errors, first apply the Signal for the setpoint
or act. value = 0. Then select under CO25 the corresponding
analog input. Adjust the offset correction under CO26 such that the
internal display is also set to Zero.
Internal offset faults are already adjusted before delivery.
Your changes will not be reset when loading the factory setting
(CO02 = -o-).
