SERVOSTAR 640/670 Instructions Manual
12/2010
Converts superfluous energy, which is fed back
during braking, into heat in the brake resistor
Clock signal
The maximum amplitude of a disturbance (on both
inputs) which a differential input can eliminate
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
Mean power which can be dissipated in the brake 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)
Enable signal for the servo amplifier (+24V)
Maximum value for speed normalization at ±10V
CANopen, PROFIBUS, SERCOS, EtherCAT
Special method of representing binary numbers
Brake in the motor, which can only be used when the
motor is at stillstand
Monitoring of the actually required r.m.s. current
Temperature and age-dependent alteration of an analog
input
Position signalling by 2 signals with 90° phase
difference, not an absolute position output
The effective value of the peak current
The r.m.s. value of the continuous current
Proportional gain of a control loop
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
Output of an analog measurement
Data packet with all the position control parameters
which are required for a motion task
Machine with several independently driven axes
Free movement of air for cooling
Optical connection between two electrically
independent systems
