Moog DM2020 Series User Manual

which serve to provide the necessary requirements for health and safety
relating to the design and construction of machinery present on the European
market. It applies to fixed, mobile, transportable and hoisting/moving.
Directive (Low
Voltage)
The Low Voltage Directive concerns machinery in which electric low voltage
circuits are present. The manufacturer must compile a technical dossier, make
a declaration of conformity, and affix the CE marking.
Dispersion towards
ground
Current (usually of reduced intensity) flowing from a wire to ground.
Dynamic braking The energy accumulated by the motor during the acceleration is converted into
heat through the braking resistor.
Directive (EMC) The EMC Directive requires that all electrical and electronic devices placed
on the market from 1 January 1996 must satisfy the essential requirements of
electromagnetic compatibility.
The essential electromagnetic compatibility requirements are met by applying
the harmonized technical standards published in the EU Official Journal.
The harmonized standards can be essentially divided into:
l Product standards
l Generic standards
l Basic standards
E
Electric Drive Electric power converter for controlling torque speed and position of a motor.
It consists of four main parts:
l Rectifier of AC mains voltage
l DC link voltage rectified and leveled
l Inverter of the rectified voltage
l Control circuit that transmits signals for the switching of the power
semiconductors of the inverter
Electrical noise Set of unwanted signals or current that overlap the useful signal, typically
transmitted on a communication channel between electronic devices.
EMC Radio frequency emitted during electronic power equipment operation, likely
to generate or induce disturbances in other electronic equipment.
Emissions Electromagnetic interference caused by electronic equipment operating at
frequencies likely to generate or induce disturbances.
Enable Signal that enables the drive.
Encoder Motor feedback component that detects a change in position of the shaft and
transmits it to the drive for controlling the motor.
Encoder, incremental Motor feedback component that detects incremental changes in the position
of the shaft and transmits that to drive for controlling the motor.
Encoder, simulated TTL encoder signals (A, B and C) differential line drivers generated by the
drive, starting from internal information, to emulate an encoder.
Encoder, sinusoidal Motor feedback component that detects incremental changes in the position
of the shaft and transmits that to the drive for controlling the motor. The
information is acquired through the reading of two sinusoidal signals that are
sampled from the drive.
EnDat 22 Serial protocol for communication with Heidenhain encoder. Allows the reading
of the position of absolute encoders, as well as updating and saving data
