List of parameters
p2505[0...n] LR motor/load motor revolutions / Mot/load motor rev
SERVO_S110-CAN Can be changed: C2(25)
(Pos ctrl),
Data type: Integer32
SERVO_S110-DP
(Pos ctrl),
P-Group: Closed loop position control
SERVO_S110-PN
Not for motor type: -

Description: Sets the load 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, p2504
Note: The gearbox factor between the encoder shaft and the motor shaft is set using p0432 and p0433.
p2506[0...n] LR length unit LU per load revolution / LU per load rev
SERVO_S110-CAN Can be changed: C2(25)
(Pos ctrl),
Data type: Unsigned32
SERVO_S110-DP
P-Group: Closed loop position control
(Pos ctrl),
Not for motor type: -
SERVO_S110-PN
(Pos ctrl)
Min
1 [LU]
Description: Sets the neutral length units LU per load revolution.
Therefore, for a rotary encoder, a reference is established between the physical arrangement and the neutral length
units LU used in the drive.
Example:
Rotary encoder, ballscrew with 10 mm/revolution, 10 mm should be broken down to units of µm (i.e. 1 LU = 1 µm).
--> One load revolution corresponds to 10000 LU
--> p2506 = 10000
Note: The position controller can only process position setpoints in the interpolator clock cycle (IPO clock cycle) in integer
length units (LU, Length Unit). This is the reason that speed setpoints that are not a multiple integer of 1 LU per IPO
clock cycle can only be realized as an average. The result speed setpoint steps are especially noticeable for a high
loop gain or when the pre-control is active. Increasing p2506 counteracts this behavior.
