6.6.6 Restrictions
Both measuring systems on a drive amplifier work widely indepen-
dently. Merely at switch-on of the drive amplifier, resp. restart of the
rho4, and with drive-controlled referencing, the position value of the ex-
ternal encoder (S−0−0053) is equated to the position value of the inter-
nal encoder (S−0−0051).
Therefore it must be ensured, that after a restart or referencing the belt
encoder value is always set to the desired value by the belt synchroni-
sation logic (reset belt encoder).
