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.
