2.2 List of parameters
Note:
While the technology controller is enabled, the following applies:
When switching off with OFF1, OFF3 and for pulse inhibit, bits 10 and 11 are simultaneously set to 1 as the controller
output is defined by the internal limiting.
Description:
Setting to assign the encoder.
The actual value preprocessing and the closed-loop position control are carried out using the assigned encoder.
Value:
0:
No encoder
1:
Encoder 1
2:
Encoder 2
Dependency:
Refer to: p0187, p0188
Notice:
For the setting p2502 = 0 (no encoder), closed-loop position control is not possible. This setting is only practical as
supportive measure to implement encoderless closed-loop speed control (e.g. if the motor encoder is defective).
Note:
The assigned encoder (p2502 = 1, 2) must be allocated an encoder data set (p0187, p0188).
Description:
Sets the neutral length units LU per 10 mm.
Therefore, for a linear scale, a reference is established between the physical arrangement and the neutral length
units LU used in the drive.
Example:
Linear scale, 10 mm should be broken down to units of µm (i.e. 1 LU = 1 µm).
--> p2503 = 10000
Note:
The assignment to the grid spacing can be achieved using this for a rotary axis with linear encoder.
LU: Length Unit
Description:
Sets the motor revolutions for the gearbox factor between the motor shaft and load shaft.
Gearbox factor = motor revolutions (p2504) / load revolutions (p2505)
