Line contactor
A line contactor is used for galvanic separation of the axis system and the supply system.
Operation without line contactor
For more information, refer to chapter Using the line contactor.
Operation without line contactor
Operation of the power supply module is possible without a line contactor.
Observe the following information:
- For the MDP90A.. power supply modules, sizes 1 and 1A, only intrinsically safe braking resistors may be used for operation without a line contactor. Using the internal braking resistor of size 1A is not permitted.
- For MDP90A.. power supply modules sizes 2 – 4, in case of a defective brake chopper, the supply system rectifier is locked internally and the energy flow to the braking resistor is interrupted.
Observe the permitted connection types in chapter Protecting the braking resistors from thermal overload.
