4.3 Control element
The control element has the following tasks:
} Controls the semiconductor on the power element
} Exchanges data between the servo amplifier and periphery
} Records and displays errors and messages
} Performs protective functions for the servo amplifier and motor
Processing of the setpoints with current, speed and position controllers is fully digital.
For communication with the periphery the servo amplifier has
} Digital inputs and outputs
} Analogue inputs for specifying the controller setpoint
} Connections for encoder systems
} Interfaces for connecting a PC (e.g. for configuration and commissioning) or a higher
level control system
4.3.1 Supply voltage 24 VDC
The control element is fed with 24 V from an isolated external power supply. Please note
the information provided under “Technical Details”.
WARNING!
Electric shock!
Safe electrical isolation must be ensured for the external power supply that
generates the supply voltage. Failure to do so could result in electric shock.
The power supplies must comply with EN 60950-1, 05/2006, EN 61558-2-6,
11/1997.
4.3.2 Digital inputs and outputs
4.3.2.1 Overview
The PMCprotego D has digital inputs and outputs for a range of applications.
The digital signals can be logically linked within the commissioning software.
