AE0ZP0EC - AC-0 SSL SENSORED - User Manual
1 INTRODUCTION
The AC-0 SSL inverter has been developed for applications such as transpallet
trucks, stacker trucks and cleaning machines with Asynchronous (AC) traction
and pump motors up to 1.2 kW (Vbatt=24 V), 1.8 kW (Vbatt=36 V) and 2 kW
(Vbatt=48 V).
The AC-0 SSL 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 described: 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 24 V AC-0 SSL with Encoder is FZ2008. The 36
V has a different part number is FZ3006.
AC-0 has also a big brother controller called AC-1, both are available in the
Sensored version. The only differences between AC-0 and AC-1 are the
maximum current (150 A vs. 250 A) 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
AC-0 and the MDI-PRC has been already developed in a standard handling here
described.
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 AC-0’s services with those extra functions asked
only on the high level trucks.
AC-0 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 AC0TXXX ZP1.07.
