These include regenerative and DC injection braking, auto/manual restart, Volts/Hz
curve selection, selectable switching frequency, adjustable acceleration and decel-
eration, and 0 - 200 Hz operation.
An isolated multifunction terminal block provides for external control of start/stop,
forward/reverse, and analog input signal following. Other functions include (3) pre-
set speeds, analog output signal (0 - 10 Volts DC), and a programmable output relay.
The KBE2 also contains the following protection features: undervoltage, overvoltage,
overtemperature, ground fault, short circuit, and I
2
t motor overload protection. The
fault codes are shown in the digital display. All models are UL Listed (USA and
Canada), CE and C-tick (N10980) approved and ISO-9002 certified.
Optional features include a DIN Rail Mounting Kit and RFI filter. An external brake
resistor is available for 2 HP and 3 HP - 230 Volt AC models and 1 HP, 2 HP, and 3
HP - 460 Volt AC models. The DownLoad Module™ (DLM) uploads and downloads
drive programs. Drive-Link™ software provides PC communications to facilitate
programming.
STANDARD FEATURES

•
Short Circuit Protection –
Shuts down the drive if a short occurs at the motor
(phase-to-phase or phase-to-ground).
•
Barrier Terminal Blocks –
Separate terminal blocks are provided for power (AC
line, motor) and external signal wiring (potentiometer, multifunction input and
output terminals, voltage and current following).
