If the drive output of a gantry with drive motors is distributed over multiple axes to achieve a more compact design and enhanced motion, these motors can be operated cost-optimized in parallel with a converter with an appropriate total power rating. The Motor Multi Connection Modules are used to protect the individual motors from the total power of the converter. Motor Multi Connection Modules contain the motor circuit breakers. Each motor circuit breaker protects one motor. Several motor circuit breakers are connected in parallel on the input side into a section for connection to a Motor Module. The Motor Multi Connection Modules can be equipped with optional analog measuring instruments built into the cabinet door for indicating the current motor currents and current output voltage of the Motor Modules.

Дизайн

In total, 4 control cabinet versions are available for connecting 12, 16, 20 or 24 motors with an appropriate number of motor circuit breakers. The motor circuit breakers are designed for a rated current of 45 A to 63 A. The motor circuit breakers are always connected at the input side into 4 groups of 3, 4, 5 or 6 motor circuit breakers for connection to Motor Modules. Up to 2 Motor Modules can be connected to one Motor Multi Connection Module for operating up to 2 sections of motors connected in parallel. As an option, depending on the control cabinet version, 12, 16, 20 or 24 ammeters for indicating the motor currents as well as 2 voltmeters for indicating the output voltages of the Motor Modules can be integrated in the cabinet door of the Motor Multi Connection Module.

Интеграция

The motors and Motor Modules are connected to the Motor Multi Connection Module in accordance with the grouping.
