Definition
Point of common coupling
The PCC is the point in the electrical power supply system where the
responsibility of the utility changes to the industrial customer. The utility is
responsible to provide clean voltage and current with respect to harmonic
distortion up to the PCC. The industrial customer is responsible not to distort
voltage and current by its electrical systems.
Proportional-integral-derivative controller
Control loop feedback system for controlling process variables
(eg, pressure, flow)
Protective earth
Power plate communication system
PPCS is an acronym for a serial communication protocol designed for data
transfer via optical fibers between AMC circuit board and INTerface circuit
boards.
Resistance temperature detector or device
The RTD is a temperature sensor where the change in electrical resistance is
used to measure the temperature.
Indicates the operating condition of a circuit or device.
Software
Short form for terminal compartment of the drive
Uninterruptible power supply
Used in the manual to indicate that the drive has reached the value "zero speed"
