Configuration Examples Chapter 11
8. Set the P60 [Lock Mon Input] parameter value to 1 for 2NC (dual-
channel equivalent) operation.
In this example application, the Lock Monitor Input (LM_In) monitors
the TLS-3 GD2 switch, which has two normally-closed (2NC) interlock
monitoring contacts.
9. Go to the next section to set the parameters that configure Safe Maximum
Speed monitoring.
Example 1: Max Speed Group
Figure 52 - Max Speed Group Parameters
Follow these steps to configure Maximum Speed monitoring for the safety
option.
1. From the Max Speed group, choose the P61 [Max Speed Enable]
parameter.
The default value is 0 (Disabled) for no maximum speed limitation.
2. Set the P61 [Max Speed Enable] parameter value to 1 (Enabled), which
monitors that the encoder feedback signal does not exceed the velocity
configured by using the Safe Max Speed parameter.
3. Choose the P62 [Safe Max Speed] parameter.
The default value is 0 rpm or mm/s. Enter a value from 0…6553.5.
4. Type the maximum allowable rpm value for velocity.
The speed is calculated in rpm, based on the Fbk 1 Units parameter setting
(0 = Rotary feedback) entered previously.
5. Choose the P63 [Max Spd Stop Typ] parameter.
