Clock signal
The maximum amplitude of a disturbance (on both
inputs) which a differential input can eliminate
Mean power which can be dissipated in the
regen circuit
Internal count pulses, 1 pulse = 1/2
Regulates the difference between the current
setpoint
and the actual value to 0
Output : power output voltage
Rectified and smoothed power voltage
Removal of the enable signal (0V or open)
electrical connection between a phase and
the protective earth (PE)
Enable signal for the servo amplifier (+24V)
CANopen, PROFIBUS, SERCOS
Free movement of air for cooling
Special format for representing binary numbers
Brake in the motor, which should only be used
when the motor is at standstill
Monitoring of the r.m.s. current that is actually
required
Position signalling by 2 signals with 90° phase
difference, not an absolute position output
Temperature and age-dependent alteration of an
analog input
The effective value of the peak current
The r.m.s. value of the continuous current
Proportional gain of a control loop
Maximum value for speed normalization at ±10V
Switch limiting the traverse path of the machine;
implemented as n.c. (break) contact
The complete assembly of all connected parts or
devices, of which at least one is movable
Set of all the position control parameters
which are required for a motion task
Machine with several driven axes
Free movement of air for cooling
Optical connection between two electrically
independent systems
