Introduction to the manual 15
Network
control
With fieldbus protocols based on the Common Industrial Protocol (CIP
TM
),
such as DeviceNet and Ethernet/IP, denotes the control of the drive using the
Net Ctrl and Net Ref objects of the ODVA AC/DC Drive Profile. For more
information, see www.odva.org
, and the following manuals:
• FDNA-01 DeviceNet adapter module User’s manual (3AFE68573360
[English]), and
• FENA-01/-11 Ethernet adapter module User’s manual (3AUA0000093568
[English]).
Parameter User-adjustable operation instruction to the drive, or signal measured or
calculated by the drive
PID controller Proportional–integral–derivative controller. Drive speed control is based on
PID algorithm.
PLC Programmable logic controller
Power unit Contains the power electronics and power connections of the drive (or inverter
module). The drive control unit is connected to the power unit.
PSL2 Protocol used in communication between the drive control unit and the power
unit
PTC Positive temperature coefficient
PU See power unit.
RDCO-0x DDCS communication module
RFG Ramp function generator.
RO Relay output; interface for a digital output signal. Implemented with a relay.
SSI Synchronous serial interface
STO Safe torque off
Supply unit The part of the drive that converts AC to DC. An IGBT supply unit (ISU) is also
capable of feeding regenerative energy back into the supply network.
TTL Transistor-transistor logic
UPS Uninterruptible power supply; power supply equipment with battery to
maintain output voltage during power failure
ZCU Type of control unit used in ACS880 drives (primarily in drive modules, or
inverter/supply units consisting of a single power module). Consists of an I/O
board built into a plastic housing.
Depending on the type of hardware, the control unit may be integrated into or
fitted onto the drive/inverter module, or installed separately.
