HELI CPD15 Service Manual

88
Battery disconnected while regen
braking.
25
5V Supply Failure
5V supply overload.
5V supply (pin 26)
outside the 5V±10％
range.
26
Digtial Out 6 Overcurrent
Digital Output 6 overcurrent.
Digital Output 6
(pin19) current
exceeded 15mA.
27
Digtial Out 7 Overcurrent
Digital Output 7 overcurrent.
Digital Output 7
(pin20) current
exceeded 15mA.
28
Motor Temp Hot Cutback
Motor temperature is too high.
Motor temperature is
too high.
The parameter adjustment of
temperature sensor is wrong.
29
Motor Temp Sensor Fault
Motor temperature sensor is not
connected properly.
Motor temperature
sensor input (pin8) is at
the voltage rail (0 or
10V).
The parameter adjustment of
temperature sensor is wrong.
31
Coil1 Driver Open/Short
(Main Open/Short)
Open or short on driver load.
Check COIL1 for open
or short.
Bad contact.
Wiring error.
32
Coil2 Driver Open/Short
(EMBrake Open/Short)
Open or short on driver load.
Check COIL2 for open
or short.
Bad contact.
Wiring error.
33
Coil3 Driver Open/Short
Open or short on driver load.

Check PD for open or
short.
Bad contact.
Wiring error.
36
Encoder Fault
Motor encoder failure.
Check encoder for
fault.
Wiring error.
37
Motor Open
Motor phase is open.
Check motor phase U,
V or W for open.
Bad crimps or faulty wiring.
38
Main Contactor Welded
Main contactor welded.
Check B+ or B-
voltage of main
contactor and
controller.
An alternate voltage path (such as
external precharge resistor) is
providing a current to the capacitor
bank.
39
Main Contactor Did Not
Close
Main contactor did not close.
Check contactor and
fuse.
Main contactor tips are oxidized.
External load on capacitor bank that
prevents capacitor bank from
charging.
Blown B+ fuse.
41
Throttle Wiper High
Throttle pot wiper voltage too high.
Replace throttle 1.
42
Throttle Wiper Low
Throttle pot wiper voltage too low.
Bring throttle pot2
wiper (pin16) voltage
above the fault
