Description of Indicator:
POWER (Green) power indicator:
If the controller is charged, this indicator lights up to indicate that controller is under normal operation.
TORQUE (Red) over-current indicator
:
T
urns red to indicate that output current of the controller exceeds client’s
pre-set current, and the controller will automatically
limit the output current to such value.
Regulation Description of Functional Potentiometer
:
MAX (Maximum Revolving Speed Limit)
It is used for limiting motor’s maximum revolving speed. Increase in clockwise rotation and decrease in
counter clockwise rotation.
IR (Torque Compensation)
Regulate “IR” enable motor work under different loads and keep re
volving speed constant (normally factory default is 0), Increase
in clockwise rotation and decrease in counter clockwise rotation.
RAMP (Soft Start/ Stop)
Regulate “RAMP” to set motor’s starting and stopping time (1
-20 S). Increase in clockwise rotation.
TORQUE (Current Limit Regulation)
Regulate “TORQUE” to set over
-current protection value of the controller; regulating range is 0-20A, Increase in clockwise rotation
and decrease in counter clockwise rotation. When reaches over-current limit value, over-current indicator (Red) lights constantly
and current is be limited to such value, at this time, continue to regulate the external potentiometer, current value is invariant(
i.e. amplitude limiting).
Driver Examination steps before Charged:
•
Firstly, check whether positive and negative connection of battery pack and driver is correct, reliable and whether input
power is within driver’s applicable range.
•
Check whether the circuit board of driver is clean, clear and without conductive metals, humidity, dew and debris
•
Check whether periphery connecting line of driver is correct and free from short circuit and ground connection.
•
Confirm that external speed governing potentiometer is at minimum position (given signal is at 0)
Common Fault Treatment:
PROBLEMS
CAUSES
RECOMMENDED SOLUTIONS
Motor is out-of-
operation
1. Wiring is incorrect.
2. Command signal is
０
V.
3. Disconnection of INHIBIT enable
terminal.
4. Current output is limited.
1. Carefully check the wiring between controller and motor
2. Regulate external potentiometer or external analogue signal
3. Contact enable terminal
4. Regulate the output current of controller after confirming that
motor is not blocked
Acceleration and
deceleration time of
motor is improper
Regulate of starting and breaking
potentiometer is inappropriate
Regulate starting and breaking potentiometer
Motor vibrates after
acting load
1. IR COMP setting is too big
2. Lack of current limit
1. Carefully regulate the setting of IR COMP
2. Regulate the TORQUE potentiometer after confirming that motor
matches well with the driver
Speed up after acting
load of motor
IR COMP setting is too small
Increase IR COMP setting
Slow down after
acting load of motor
IR COMP setting is too big
Decrease IR COMP setting
