K Kp, P-gain Proportional gain of a control loop
L Limit speed (final speed) Maximum value for speed normalization at ±10V
Limit switch Switch limiting the traverse path of the machine;
implemented as n.c. (break) contact
M Machine The complete assembly of all connected parts or
devices, of which at least one is movable
Motion block Data packet with all the position control
parameters which are required for a motion task
Multi-axis system Machine with several independently driven axes
N Natural convection Free movement of air for cooling
O Optocoupler Optical connection between two electrically
independent systems
P P-controller Control loop with purely proportional behavior
Phase shift Compensation for the lag between the electro-
magnetic and magnetic fields in the motor
PI-controller Control loop with proportional and
differential behavior
Position controller Regulates the difference between the position
setpoint and the actual position to 0
Output: speed setpoint
Potential isolation electrically decoupled, electrical isolation
Power contactor System protection device with phase monitoring
Pulse power of the regen circuit Maximum power which can be dissipated in the
regen circuit
R regen circuit Converts superfluous energy fed back by the
motor during braking (regenerated energy) into
heat.
Reset New start of the microprocessor
Resolver/digital converter Conversion of the analog resolver signals into
digital information
Reversing mode Operation with a periodic change of direction
Ring core Ferrite rings for interference suppression
ROD-interface Incremental position output
S Servo amplifier Control device for regulating the speed, torque
and position of a servomotor
Setpoint ramps Limits for the rate of change of the speed setpoint
Short-circuit here: electrically conductive connection between
two phases
Speed controller Regulates the difference between the speed
setpoint and the actual value to 0
Output : current setpoint
SSI-interface Cyclically absolute, serial position output
Supply filter Device to divert interference on the power supply
cables to PET
T Tachometer voltage Voltage proportional to the actual speed
Thermostat (contact) Temperature-sensitive switch built into the
motor winding
Tn, I-integration time Integral component of a control loop
Z Zero pulse Output once per turn from incremental encoders,
used to zero the machine
