How to prevent measurement errors

To ensure that the encoder operates correctly, it is necessary to mount it accurately as

described in section 4�1 to 4�4, which includes correct mounting of the torque arm�

The radial runout of the drive shaft should not exceed 0�2 mm (0�03 mm recommended),

to prevent an angle error�

An angle error may be reduced by increasing the length of L1*� Make sure that the length

L2 of the torque arm, see below, is at least equal to L1**�

The angle error Δρ

Δρ

= ±90°/π · R/L1

with R: Radial runout in mm

L1:

Example:

For R = 0.06 mm and L1 = 69.5 mm the resulting angle error Δρ

* For this different braces for the torque arm are available on request�

** If L2 < L1, L2 must be used in the calculation formula�
