Glossary
C
Clock
Clock signal
Common-mode voltage
The maximum amplitude of a disturbance (on both
inputs) which a differential input can eliminate
CONNECT- modules
Modules built into the servo amplifier, with integrated
position control, which provide special versions of the
interface for the connection to the higher-level control
Continuous power of regen circuit
Mean power which can be dissipated in the regen circuit
Counts
Internal count pulses, 1 pulse = 1/4096 turn
-1
Current controller
Regulates the difference between the current setpoint
and the actual value to 0
Output : power output voltage
D
DC-link
Rectified and smoothed power voltage
Disable
Removal of the enable signal (0V or open)
E
Enable
Enable signal for the servo amplifier (+24V)
F
Final speed
Maximum value for speed normalization at ±10V
Fieldbus interface
here: CONNECT modules: CAN-CONNECT
and PROFIBUS-CONNECT
G
GRAY-code
Special method of representing binary numbers
H
Holding brake
Brake in the motor, which can only be used when the
motor is at stillstand
I
I²t threshold
Monitoring of the actually required r.m.s. current
Input drift
Temperature and age-dependent alteration of an analog
input
Incremental encoder interface
Position signalling by 2 signals with 90° phase
difference, not an absolute position output
Ipeak, peak current
The effective value of the peak current
Irms, effective current
The r.m.s. value of the continuous current
K
Kp, P-gain
Proportional gain of a control loop
L
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
Monitor output
Output of an analog measurement
Motion-block
Data packet with all the position control parameters
which are required for a motion task,
only when a CONNECT- module is present
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
