INU Inverter unit of the drive. The INU converts the DC voltage to the
required AC motor voltage and frequency.
IOEC module The IOEC module is an active input and output device for digital and
analog signals.
Line voltage RMS voltage of the main power supply of the drive
MCB Main circuit breaker
The MCB is a major protection device of the drive and is the main
connection and disconnection point between the main power
supply and the drive.
MCD Minimum creepage distances
Molykote Brand name for lubricants
PCB Printed circuit board
PCC 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.
PID controller Proportional-integral-derivative controller
Control loop feedback system for controlling process variables (eg,
pressure, flow)
PE Protective earth
PPCS 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.
RTD Resistance temperature detector or device
The RTD is a temperature sensor where the change in electrical
resistance is used to measure the temperature.
Safeline ABB synonym for uninterruptable power supply
Supervisory signal Indicates the operating condition of a circuit or device.
SW Software
TC Short form for terminal compartment of the drive
UPS Uninterruptible power supply
Zero speed
threshold Used in the manual to indicate that the drive has reached the value
“zero speed” that is set in a parameter. The value can be set in the
range of 0 and maximum speed (the unit for the speed is rpm).
