11 Appendix
11.1 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 integra-
ted position control, that provide special versions
of the interface for the connection to the higher-
level control.
Counts Internal count pulses, 1 pulse = 1/2
20
turn
-1
Continuous power of regen circuit Mean power that can be dissipated in the regen
circuit
Current controller Regulates the difference between the current
setpoint and the actual value to 0
Output : power output voltage
D DC bus link Rectified and smoothed power voltage
Disable Removal of the ENABLE signal (0 V or open)
E Earth short electrical connection between a phase and
the protective earth (PE)
ENABLE Enable signal for the servo amplifier (+24 V)
F Fieldbus interface CANopen, PROFIBUS, SERCOS etc.
Final speed (limit speed) Maximum value for the speed normalization at
±10 V
G GRAY-code Special format for representing binary numbers
H Holding brake Brake in the motor, that can only be used when the
motor is at standstill
I I²t threshold Monitoring of the r.m.s. current that is actually
required
Input drift Temperature and age-dependent alteration of an
analog input
Incremental encoder interface Position signaling by 2 signals with 90° phase
difference (i.e. in quadrature), is 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 speed (final speed) Maximum value for speed normalization at ±10 V
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
