2.2 TERMS AND DEFINITIONS USED IN THE MANUAL

A: amperes.
DC Busbar (DC Link): intermediary circuit of the servo drive; voltage in direct current obtained by rectifying the
power supply alternate voltage or by external supply; it supplies the output inverter bridge formed by the IGBTs.
U, V and W leg: set of two IGBTs of the servo drive output phases U, V and W.
°C: celsius degree.
°F: fahrenheit degree.
AC: alternate current.
DC: direct current.
CFM: cubic feet per minute.
Pre-Charge Circuit: it charges the capacitors of the DC busbar with limited current, preventing greater current
peaks at the energizing of the servo drive.
HP: horsepower = 746 Watts; Power measurement unit, normally used to indicate the mechanical power of
electric motors.
Heatsink: metal part designed to dissipate the heat produced by power semiconductors.
RFI Filter: radio Frequency Interference Filter - Filter to reduce interference in the radio frequency band.
Switching Frequency: commutating frequency of the IGBTs of the inverter bridge, normally expressed in kHz.
ft: foot - unit of length equivalent to 304.8 mm.
HMI: human machine interface; device that allows viewing and changing the parameters, alarms and faults of the
servo drive. It features navigation keys and LED display.
