Page - 6/73 AESZP0BA – AC1 SSL SENSORED - FREE VERSION - User Manual

1 INTRODUCTION

The AC1 SSL SENSORED inverter has been developed for applications such as

electric transpallets, golf car, order pickers, sit on stackers with Asynchronous

(AC) traction motors up to 2.5KW.

The AC1 SSL SENSORED can be supplied in two versions:

1) Sensored version using an Encoder (Sensor Bearing) in the Motor axle

2) SenseCoils version using special auxiliary windings in the motor.

Here the Sensored Version is descripted: it adopts an Encoder integrated in the

Ball Bearing (Sensor Bearing).

The Encoder fills up the truck performance, respect to the Sensorless and Sense

Coils versions, with lower minimum speed, the “stop on the ramp” service and a

smoother inversion; on the other hand the reliability gets penalized by the fragile

mechanics and inaccessible position of the Sensor Bearing.

The correct part number for the 24V AC1 SSL SENSORED with Encoder is

FZ2018. The 36V has the part number FZ3010. The 48V part number is FZ5053.

AC1 has also a small brother controller called AC0, both are available in the

Sensored version. The only differencies between AC1 and AC0 are the maximum

current (250A vs. 150A) and the dimensions.

All the Zapi AC controllers have the CAN Bus communication peripheral and a

Serial Link embedded: the SW for the communication via CAN Bus between the

AC1 and the MDI-PRC has been already developed in a standard handling here

descripted.

MDI-PRC is a Zapi module to be mounted on the dashboard of the truck to inform

with a display about the state of the truck and provided with a Leds battery

charge indicator. Besides, the MDI-PRC can drive four electrovalves (two

proportional and two On/Off type) for an advanced hydraulics handling. MDI-PRC

is the natural choice to fill the AC1’s services with those extra functions asked

only on the high level trucks.

AC1 SSL has an additional analogue input (CNA #13) suited to receive a motor

thermal sensor (KTY84-130).

The reference SW release for this manual is AC1TXXX ZP1.07 .
