Speed control loop
Drive operating mode with SERCOS and ANALOG interfaces in which
the drive sets the motor speed or the velocity of the moved machine part
with a high dynamic response as a function of the applied velocity
command.
Idling torque, friction torque
The torque required to move the drive and the attached mechanical
construction at constant velocity (machine-related).
Am electromagnetic brake built into the servo motor as an option. It
serves to protect the AC servo motor (servo axis) again involuntary
movement when shut down. The brake is closed when de-energized. It
is not intended as a brake in the event of an E-STOP!
DLF
Sinusoidal position encoder signals are conditioned in the drive control-
ler at high resolution (multiplication factor 2048).
IDG
An optional feature for resolver feedback on AC servo motors for digital
intelligent drives for absolute measurement of the rotor position over
4096 revolutions.
Position encoder, relative position encoder
Incremental encoders supply a defined number of measuring cycles per
revolution or stroke. Position measurement referred to a reference point
is achieved by traversing to the reference point after switching on the
supply voltage with continuous direction-biased counting of the meas-
urement cycles in the NC control or the drive.
DAE
The incremental encoder emulation is an integral part of "ANALOG
interfaces with incremental encoder emulator DAE 1.1". It allows the
output of the drive’s internal position or angle information. This informa-
tion is used by the related NC control as a position actual value signal.
Plug-in card
The transition point for signal interchange between drives, control
systems, encoders, etc. In digital intelligent drive controller units the
basic interfaces are permanently installed. Over and above this, op-
tional, variable application-related interfaces may be plugged into the
controller units.
Loop gain factor
In a position control with a lag error the Kv factor indicates the velocity (m/
min) at which a lag error of 1 mm is occurs.
