A) Traction and pump motor controller
Tractor motor controller type: ZAPI ACE2 48V/350A
Pump motor controller type: ZAPI ACE2 48V/500A
ACE2 controller which is three phase AC asynchronism motor inverter controls
traction motor and pump motor. It has regenerative brake function, CAN bus
port and digital control function (based on motor speed feedback).
Allowable working environment temperature: -30℃~+40℃， Max. allowable
working temperature: 85℃.
Protection function of the ACE2 traction motor controller:
a) battery polarity protection b) incorrect connection protection
c) over heat protection; overload protection; short circuit protection
d) controller protection degree:IP65;
e) out of control protection f) battery over discharging protection
g) Mis-starting protection
The following functions can be realized through controller’s hand console:
a) On line inspection and adjusting on traction and lifting control system
b) On line correction on travelling accelerator and lifting speed adjusting signal
c) Fault detection and inquiry on traction and lifting control system
Important Note:
◆ Test the truck with wheels raised after the controller being fixed, in that case
there will be no danger even the connection is in error.
◆ A certain amount of voltage will remain in filter capacitance after the turn off of
the electric switch. Cut off the battery and make the remained voltage short circuit by
connecting the 10-100ohm resistance to the inverter before checking the inverter.
◆ The quality is assured by the producer. When there is a fault, inform the producer
of the after-sale service. Do not repair as will unless getting the permission from the
