Tip To view the following fields, click in a blank space in the Value tab and drag the mouse
upward.
•
Shaft Friction (Bf) — set as desired.
•
Rotational Inertia (J) — set as desired.
•
Rated Rotational Speed (NN) — set as desired.
•
Load Torque (Tl) — set as desired.

2.2.9 Rated Relay
The magnetic relay is a coil with a specified inductance that causes a contact to open or close
when a specified current (Ion) charges it.
Note Refer to the Component Reference Guide for a more detailed discussion of relays.
 To adjust the component’s tolerances:
1. Double-click on the placed component and click the Value tab.
2. Change the following values as desired:
•
Animation Delay Factor — increase this number to slow the speed of animation of the
symbol blowing. This is not a real-time value.
•
Coil Inductance — set as desired.
•
Coil Resistance — set as desired.
•
On Current (Ion) — set as desired.
•
Off Current (Ioff) — set as desired .
•
Maximum Rated Voltage — the maximum voltage allowed. If this value is exceeded
during simulation, the relay blows.
•
Maximum Rated Current — the maximum current allowed. If this value is exceeded
during simulation, the relay blows.
3. Click OK.
