MDP92A.. power supply module in direct mode
The following 3 connections exist:
Circuit 1 | Circuit 2 | Circuit 3 |
|---|---|---|

|
[1] | Line contactor | [2] | Braking resistance | [3] | Internal temperature switch | [4] | PLC |
Connection 1
If the internal temperature switch responds, note the following:
- The power supply module switches the axis modules and the MOVIDYN decentralized drives® to "Output stage inhibit".
- A response by the PLC is not required.
- It is not necessary to disconnect the line connection using an external switching device.
Connection 2
The signal contact is only evaluated in the PLC.
If the internal temperature switch responds, note the following:
- The PLC must disconnect the power supply.
- After disconnecting the power supply, the axis modules and the MOVIDYN decentralized drives® respond to line phase failure according to the parameterized response.
With circuit 2, it is possible that the PLC finishes the current travel cycle although the thermal circuit breaker has tripped. Only then is the power supply disconnected. In this case, the residual braking energy Wres = PBR_nom × 20 s must not be exceeded.
Connection 3
The signal contact directly affects the line contactor.
If the internal temperature switch responds, note the following:
- A response by the PLC is not required.
- After disconnecting the power supply, the axis modules and the MOVIDYN decentralized drives® respond to line phase failure according to the parameterized response.
