Commissioning the functions "STO", "SBC" and "SS1"

Incompatible version in the Motor Module

If there is no compatible version in the Motor Module, the Control Unit will respond as follows

on transition to Safety commissioning mode (p0010 = 95):

● The control unit outputs the fault F01655 (SI CU: aligning the monitoring functions). The

fault initiates fault response OFF2.

● The Control Unit triggers safe pulse suppression via its own Safety switch-off signal path.

● If parameterized (p1215, p9602), the motor holding brake is closed.

● The fault can only be acknowledged after the Safety functions have been blocked (p9601).

Duplicate the parameters for the 2nd channel

After you have parameterized all safety functions, the drive must accept the settings.

To accept the settings in the drive, it must be online.

1. To accept the settings and deactivate the safety functions, click the

The following steps are executed:

– The parameter settings are copied from CPU 1 to CPU 2.

– Copying RAM to ROM is offered.

– Safety mode is deactivated, the icon now has a yellow border.

2. Go offline with the drive.

You can now continue with the further settings of the parameterization. The dialogs are no

longer deactivated.

Behavior when copying

For the encoder parameters (p9515 to p9529), which are used for safe motion monitoring, the

following procedure applies when copying:

● The following applies to safety-related functions that have not been enabled (p9501 = 0):

The parameters are automatically set during startup in the same way as the corresponding

encoder parameters (e.g. p0410, p0474, ...).

● The following applies to safety-related functions that have been enabled (p9501 > 0):

The parameters are checked against their corresponding encoder parameters (e.g. p0410,

p0474, ...).
