Enclosure Rating: IP20.
Overload: 150% x 60 seconds every 10 minutes, 175% x 2 seconds at start.
Speed Control Range: 0-600Hz.
Braking: Full load for 90 seconds every 120 seconds to 175 Ohm minimum, 800 Ohm Maximum external resistor (not supplied) – see the Resistor options linked below or use the ‘Which Resistor’ button on this page.
Keypad: See optional products linked below.
Features: 2 x Analogue Inputs, 5 x Digital Inputs, 1 x Analogue Output, 1 x Digital Output, 1 x Relay Contact set.
DC Bus terminals with charge limit in circuit for DC supply from PV panels, or for common bus energy saving applications.
‘Safe Torque Off’ (STO) function to SIL 3.
Programmable from a PC via ‘DriveWindow’ or using the ABB FlashDrop tool.
AC Input Voltage: 380-480V Three Phase at 50/60Hz ±5%.
AC Input Current: 4.1A, or 2.3A when supplied via a minimum 6.4mH AC Input choke (see the products linked below) to reduce the metered kVA from 2.8kVA per drive, to 1.6kVA.
