“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 temperature 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 temper
ature 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
Throttle invalid
Brake
Pump stops working
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”.
Troubleshooting：Correct open
circuit/short circuit, restart output.
32 Coil2 Driver Open/Short
Driver 2 output shut
1. Connected load open or short.
2. Connecting pin stained.
3. Wrong wiring.
Reason： Driver 2 output(pin 5) is
either open or shorted. This fault
can be set only when “EM brake
Type” set to 0.
Troubleshooting：
Correct open or
short circuit, restart output.
32 EM Brake Open/Short
Electromagnetic brake disconnects
Throttle invalid
Brake
1. Connected load open or short.
2. Connecting pin stained.
3. Wrong wiring.
Reason：
EM Brake output(pin 5)
is either open or shorted. This
fault only occurs when “EM brake
Type” set to 0.
Troubleshooting：
Correct open or
