1.2 GENERAL DESCRIPTION
ZAPI COMBI SEM-1 controller performs all the electric functions that are usually
presents in transpallet, stacker, low order picker etc.
The controller can perform the following functions:
-
Traction controller for SEM motor; full-bridge on the field, half-bridge on the armatu-
re.
-
Lifting controller for series excited motors.
-
Drivers for ON/OFF electrovalves and for one proportional valve (electrodistributor)
-
Interface for serial tiller head
-
MDI interface (Multifunction Digital Instrument) battery discharge indicator,
hourmeter, alarms, programmed maintenance.
1.3 MAIN FEATURES
-
High frequency MOSFET controller (high efficency, silent, etc.).
-
Speed control with regenerative braking (controls the truck also on the slope)
-
Idraulic functions control with different programmable speeds and ramps, It is
possible to use proportional functions.
-
Lowering speed control through proportional valve.
-
All the parameters are programmable by means of the ZAPI console.
-
Complete diagnosis through console or MDI.
-
High temperature protection with current reduction.
-
Drivers real time diagnosis (electro-brake, general contactor and proportional valve.
-
Electrobrake and general contactor are controlled with a PWM.
-
Drivers protected against short-circuits.
