2 SPECIFICATIONS
2.1 General features
Within the ZAPIMOS family, the ACE3 inverter (E stands for evolution) is a controller
designed to control AC induction, BLDC and PMAC motors, in the range from 10 kW
to 20 kW continuous power, used in a variety of battery-powered material-handling
trucks.
Typical applications include, but are not limited to: counterbalanced trucks with load
up to 5 tons, HLOP (Vna), GSE, tow tractors and airport ground support vehicles,
aerial-access equipment (telescopic boom and scissor lift).
The main inverter features are:

16 bits microcontroller for motor control and main functions (master
microcontroller), 384+ Kbytes embedded Flash memory

16 bits microcontroller for safety functions (supervisor microcontroller), 320+
Kbytes embedded Flash memory

Field-oriented motor-control algorithm

Smooth low-speed control

Zero-speed holding control

Zapi patented sensorless and sense-coil control

Driver for line-contactor coil

Driver for electromechanical brake

Drivers for PWM-modulated voltage-controlled electrovalves and for one
PWM-modulated current-controlled proportional valve

Overload, short-circuit and open-load protection

Thermal cutback, warnings and automatic shutdown provide protection to the
motor and the controller

Optically isolated and ESD-protected CAN bus interface

Software downloadable via serial link (internal connector) or CAN bus
interface (external connector)

Diagnostics provided via CAN bus interface using Zapi CAN Pc Tool

Rugged sealed housing and connectors meeting IP65 environmental sealing
standards for use in harsh environments
ACE3 controller can be supplied in two I/O configurations and three voltage ratings:

Standard Version
(24V, 36/48V, 80V): with a 23-poles Ampseal connector.

Premium Version
(24V, 36/48V, 80V): with an additional 23-poles Ampseal
connector for enhanced I/O capabilities.
Moreover, two power-rating variants are available (see paragraphs 2.2 and 2.3):

ACE3
: base power ratings.

ACE3 Power
: increased power ratings.
