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
E
Earth short
electrical connection between a phase and
the protective earth (PE)
Enable
Enable signal for the servo amplifier,
Hardware-Enable with 24V signal to X3,
Software-Enable command by setup Software,
fieldbus or permanently set.
Both are required for enabling the amplifier.
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
