Configuration Examples Chapter 11
12. Enter 5, 9, or 12V to monitor voltage in accordance with the encoder’s
specifications, or enter 0 (default) to disable encoder voltage monitoring.
13. Choose the P42 [Direction Mon] parameter.
14. Set the P42 [Direction Mon] parameter value to 0 (default), which equals
Disabled.
You may disable Safe Direction Monitoring if only one direction of
rotation is possible or there is no safety-related restriction on the direction
of rotation.
15. Go to the next section to set the parameters found in the Stop parameters
group.
Example 1: Stop Group Settings
Figure 49 - Stop Group Parameters
Follow these steps to configure the Stop operation of the safety option.
1. From the Stop group, choose the P44 [Safe Stop Input] parameter.
2. Set the P44 [Safe Stop Input] parameter value to 1 (default) for 2NC
(dual-channel equivalent) operation.
In this example application, the Safe Stop input (SS_In) monitors an E-
Stop button with two normally-closed (2NC) contacts.
3. Choose the P45 [Safe Stop Type] parameter.
TIP The P33 [Fbk 1 Speed] parameter displays the output speed of the encoder as a
value between -214,748,364.8…214,748,364.8 rpm based on the encoder’s
configuration. You do not need to enter a setting or value for this parameter.
