Interaction with other functions
11.2 Setpoint exchange
2- -encoder system
If the SI axis has two encoders, when changing over to the non--SI axes, it is not
permissible that the second safety encoder is de--coupled. Both SI encoders must
be continuously used. The gearbox ratio between the SI axis and the non--SI axes
must be taken into account when configuring the SI gearbox ratios.
STOPS
The setting MD36964 SAFE_IPO_STOP_GROUP <> 0 is not permissible for the
SI axis, as this causes the interpolating relationships to be cancelled.
Brake test
The brake test can only be carried--out in the SI axis. The SI axis must have the
drive checking function for the brake test.
Acceptance test
The acceptance test for non--SI axes must be manually carried--out and logged.
The acceptance test does not provide any support.
