P P-controller Control loop with purely proportional behaviour

phase shift Compensation for the lag between the electro-

magnetic and magnetic fields in the motor

PID-controller Control loop with proportional, integral and

differential behaviour

PID-T2 Filter time constant for the speed controller output

position controller Regulates the difference between the position

setpoint and the actual position to 0

Output : speed setpoint

potential isolation electrically decoupled

power contactor System protection device with phase monitoring

pulse power of the regen circuit Maximum power which can be dissipated in the

regen circuit

R regen circuit Converts superfluous energy, which is fed back

during braking, into heat in the regen resistor

reset New start of the microprocessor

reversing mode Operation with a periodic change of direction

ROD-interface Incremental position output

S servo amplifier Control device for regulating the speed, torque

and position of a servomotor

setpoint ramps Limits for the rate of change of the speed

setpoint

short-circuit here: electrically conductive connection between

two phases

speed controller Regulates the difference between the speed

setpoint and the actual value to 0

Output : current setpoint

SSI-interface Cyclic-absolute, serial position output

supply filter Device to divert interference on the power supply

cables to PE

T T-tacho, tachometer time constant Filter time constant in the speed feedback of

the control loop

tachometer voltage Voltage proportional to the actual speed

thermostat Temperature-sensitive switch built into the

motor winding

Tn, I-integration time Integral section of a control loop

Z zero pulse Output once per turn from incremental encoders,

used to zero the machine
