Fault display
3. Too large battery impedance.
4. When regenerating braking,
battery disconnects.
Troubleshooting ：
Reduce
capacitor voltage.
25 +5V Supply Failure
No fault(unless VCL set the
incurred fault)
1. External load impedance is too
low.
Reason：
5V supply outside the
5V±10% range
Troubleshooting ： B
ring voltage
within range.
26 Digital Out 6 Failure
Digital Out 6 driver is not active.
1. External load impedance is too
low.
Reason：
Digital Output 6 current
exceeds15mA.
Troubleshooting：
Adjust load, set
“set_digout()” by VCL, and restart.
27 Digital Out 7 Overcurrent
The Digital Out 7 driver is not
active
1. External load impedance is too
low.
Reason：
Digital Output 7 current
exceeds15mA.
Troubleshooting：
Adjust load, set
“set_digout()” by VCL, and restart.
28 Motor Temp Hot Cutback
Driving torque reduced.
1. Motor temperature reaches or
exceeds parameter limit, thus
cause current output reduce.
2.
Motor temperature parameters
incorrect.
3. If motor does not apply
temperature sensor, programming
parameter “Temp compensation”
and “Temp
cutback” must set
“OFF”.
Reason：
Input voltage value of
motor temperature sensor is 0 or
larger than 10V.
Troubleshooting ：
Return the
motor temperature to be within
the permitted limits.
29 Motor Temp Sensor Fault
Max. speed drops to LOS status
and motor te
mperature cutback
invalid.
1. Motor temperature sensor is
connected wrongly.
2. If motor does not apply
temperature sensor, programming
parameter “Temp compensation”
and “Temp cutback” must set
“OFF”.
Reason：
Input voltage value of
motor temperature sensor
is 0 or
larger than 10V.
Troubleshooting: Adjust input
voltage value of motor
temperature sensor to the normal
scope.
31 Coil 1 Driver Open/Short
Driver 1 output shut
1. Connected load open or short.
2. Connecting pin stained.
3. Wrong wiring.
Reason：
Driver 1 (pin 6) is either
open or shorted. This fault can be
set only when “Main Enable” set
to “OFF”.
Troubleshooting：
Correct open or
short circuit, restart output.
31 Main Contactor Coil Open/Short
Motor stops working
Main contactor disconnects
Electromagnetic brake disconnects
1. Connected load open or short.
2. Connecting pin stained.
3. Wrong wiring.
Reason：
Main contactor driver
(pin 6) is either open or shorted.
This fault can
be set only when
“Main Enable” set to “ON”.
