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)
Dependency: Refer to: p0432, p0433, p2505
