HTL High-threshold logic
ID run Motor identification run. During the identification run, the drive will identify
the characteristics of the motor for optimum motor control.
IGBT Insulated gate bipolar transistor; a voltage-controlled semiconductor type
widely used in inverters due to their easy controllability and high
switching frequency
I/O Input/Output
JCU Control unit of the drive module. The JCU is installed on top of the power
unit. The external I/O control signals are connected to the JCU, or
optional I/O extensions mounted on it.
JMU Memory unit attached to the control unit of the drive
JPU Power unit; see the definition below.
LSB Least significant bit
LSW Least significant word
MSB Most significant bit
MSW Most significant word
Parameter User-adjustable operation instruction to the drive, or signal measured or
calculated by the drive
PI controller Proportional-integral controller
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 connections of the drive module. The
JCU is connected to the power unit.
PTC Positive temperature coefficient
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
TTL Transistor-transistor logic
UIFI xxxx Firmware of the ACS850 drive
