Zapi DUALACE2 New Generation Controller User Manual 2020 – Dual AC Traction Inverter PDF

Description

Zapi DUALACE2 New Generation Controller User Manual

The Zapi DUALACE2 NEW GENERATION is a dual-motor controller designed to manage a pair of AC induction, PMSM, SRM and SRPM motors in the 4 kW to 12 kW continuous power range. This 169-page user manual, released by Zapi S.p.A. in 2020, gives installers, integrators and service technicians the complete technical documentation needed to install, configure, program and troubleshoot the controller in battery-powered material handling vehicles.

Typical applications covered by the manual include counterbalanced trucks with loads up to 3 tons, HLOP (VNA), reach trucks, tow tractors, airport ground support vehicles, aerial-access equipment (telescopic boom and scissor lifts) and e-mobility vehicles. Both the Standard (23-pin Ampsel) and Premium (35-pin Ampsel) versions are documented, including dual AC traction, combi AC (traction + pump), dual BL traction with Hall sensors, dual BL traction with sin/cos sensors, and CAN-controlled configurations.

This is more than a wiring reference. The manual walks through field-oriented motor control, the dual-microcontroller architecture used for safety functions, and the full parameter list that governs how each traction and pump motor behaves. Every I/O pin on both the 23-pole and 35-pole Ampsel connectors is documented with its default Zapi function and the alternative functions available through customized software, so you can map the controller into a vehicle harness without guessing.

Installation chapters cover the practical details that decide whether the controller survives: mounting surface preparation and thermal grease, the torque values for power connections (13-15 Nm), cable routing for CAN and I/O to avoid noise coupling, ESD precautions, and how to insulate the truck frame from the power line. The manual also explains the pre-charge sequence, main contactor timing, and the conditions under which the controller refuses to close the main contactor.

Configuration and Programming

Programming is handled through the Zapi PC CAN Console or the Zapi Smart Console over the CAN bus, since the DUALACE2 New Generation has no external serial connector. The manual documents every parameter group: Parameter Change, Set Options, Adjustments, Special Adjustment, Hardware Setting and SLV HW Setting. It also covers the acquisition procedures for the accelerator (PROGRAM VACC), lift/lower potentiometers, steering sensor, and the absolute position sensor acquisition needed for PM motors.

Because the controller supports both torque mode and speed mode, you can tune the machine for the driving feel the application needs. Regenerative braking, release braking, inversion braking, deceleration braking, pedal braking and speed-limit braking each have their own ramps. Steering curves, throttle profiles and torque profiles are all defined in the manual, along with the thermal cutback curve that starts at 85 degrees C and reduces current toward 0 A at 105 degrees C.

Diagnostics and Maintenance

The diagnostic system is one of the strongest parts of the document. Every alarm from the master microcontroller and the supervisor microcontroller is listed with its effect, the condition that triggers it, the restart procedure, and the CAN open code and Zapi code. Troubleshooting sections explain how to isolate the fault, from encoder errors and sin/cos direction faults to contactor driver issues, VACC out-of-range, motor phase shorts, thermal sensor problems and watchdog alarms. The alarm logbook stores the most recent events with hour-meter readings and temperature, and the on-board red LED flashes the two-digit code so you can read faults without a console.

Periodic maintenance is covered with a three-month check schedule for contactors, microswitches, battery and motor cables, pedals and tiller mechanisms. The appendices add a PC CAN Console user guide and a Zapi Smart Console user guide, including parameter download, alarm logbook access and USB parameter saving.

What This Manual Enables

With the Zapi DUALACE2 New Generation user manual, a technician can commission a new controller from scratch, verify every input and output, set up dual traction or traction-plus-pump operation, acquire the position sensor on a PM motor, and interpret any diagnostic code the controller raises. The specifications chapter provides the current and voltage ratings needed to fuse and cable the installation correctly, and the connection drawings cover the full range of Standard and Premium configurations.

Correct procedures matter here. The controller manages high power levels and high torque, and a wiring error or a wrong parameter can cause the vehicle to move in the wrong direction or at the wrong speed. The manual’s safety notices, pre-power-up checklist and discharge procedure for the DC-link capacitors are there to prevent equipment damage and personal injury. Having the exact Zapi documentation for this controller means you work from the manufacturer’s own pinouts, thresholds and parameter ranges rather than from generic assumptions.

IMAGES PREVIEW

The manual is delivered as an instant PDF download after purchase. No shipping, no waiting. It opens on any device – laptop, tablet or phone – and can be printed if you prefer a paper copy in the workshop. Keep it on the service computer or in the truck’s maintenance file, and you have the complete Zapi reference for the DUALACE2 New Generation controller whenever a fault code, a parameter change or an installation question comes up.
