Note:
Anyway please first to do identification angle operation.
And please don't try to connect the controller to user program while the motor is still running, let
alone change the setting in user program or Android App. That is to say, if you want to connect
controller to user program or try to do programming, please stop the motor first.
This is the most important thing.
Chapter 2 Features and Specifications
2.1 General functions
(1) External LED error codes indicator. Customers can read the error code in PC
software or Android Tablet also.
(2) Monitoring battery voltage. It will stop driving if the battery voltage is too high and it
will progressively cut back motor drive power as battery voltage drops until it cuts
out altogether at the preset “Low Battery Voltage” setting.
(3) Built-in current loop and over current protection.
(4) Configurable motor temperature protection range.
(5) Current cutback at low temperature and high temperature to protect battery and
controller. The current begins to ramp down at 90
℃
case temperature, shutting
down at 110
℃
.
(6) The controller keeps monitoring and battery recharging voltage during regen
braking.
(7) Maximum reverse speed and forward speed can be configured between 20% and
100% respectively and separately.
(8) A 4pin connector to RS232 port and a Z-TEK USB to RS232 cable allows for
configuration, programming and software upgrades using the tablet which must be
based on Android OS now. People can do the same things on PC software by using
a standard USB to RS232 cable instead.
(9) Provision of a +5 volt and +12 volt output to supply various kinds of hall sensors.
(10) 5 switch inputs which are activated by connection to 12V. Default to throttle switch,
brake switch, reversing switch, forward switch and Boost switch.
(11) 3 analog 0-5V inputs that default to throttle input, Brake analog input and motor
temperature input
(12) Copy signal of one of sensors.
(13) Configurable boost switch. Enables the maximum output power achievable if the
switch is turned on. The effect is the same as full throttle position even if you don
‟t
turn throttle at all.
(14)
12V brake switch input used different port from motor temperature sensor. You can
use both brake switch and motor temperature sensor functions at the same time on
the latest version. Pin 25 is 12V brake switch input port.Pin1
is motor temperature
sensor input port.
