100Base-TX
Ethernet network standard based on symmetrical copper cables in which the nodes are
connected to a switch via copper cables twisted in pairs (shielded twisted pair, CAT 5e
quality level).100Base-TX is the subsequent progression from 10Base-T and includes those
properties with the option of a transfer speed of 100Mbps (Fast Ethernet).
Discharge
A discharge designates the process that causes the discharge of the DC link capacitors.
Requirements for the discharge process: the mains supply is disconnected and no energy
flows back from the motor to the drive controller.
Discharge time
Period until the DC link capacitors are sufficiently discharged until safe operation of the
device is possible.
Electronic nameplate
STOBER synchronous servo motors are generally equipped with absolute value encoders
that provide a special memory. This memory includes the electronic nameplate, i.e. all
typerelevant master data as well as special mechanical and electronic values of a motor.
When you operate a drive controller with a STOBER synchronous servo motor and an
absolute value encoder, the electronic nameplate is read and all motor data transferred if
the drive controller is connected online. The drive controller automatically determines the
associated limit values and control parameters from this data.
PTC thermistor
Thermistor whose resistance significantly changes with temperature. When a PTC
thermistor reaches its defined nominal response temperature, the resistance increases
dramatically, by twice or more the original resistance to several kOhms. PTC thermistors
allow for effective motor protection as PTC drillings.
Self-discharge
Passive running process that causes the DC link capacitors to discharge even when no
electrical load is connected.
Time between energizing two devices
Specified time span between energizing two devices.
