Lifting drive

The illustration below shows the basic configuration of an inverter for powering a drive for lifting ap-
plications like hoists or roll-up gates. A motor with a mechanical brake is used to ensure that the load
cannot slip down when the motor is off.
When the end position is reached the motor is turned off by a limit switch. After this it can only be ac-
tivated in the other direction.
In the wiring diagram on the next page the mechanical brake is controlled via the RUN terminal. The
frequency at which the brake is released can be set with parameter 13.
