Increase the low-speed filter number if there is
current noise when running at low speed, or
decrease the low-speed filter number to enhance
the system’s response.
A7.04 PG disconnection detecting time
This parameter defines the continuous detecting
time for disconnection fault of PG.
When set A7.04 to 0, then the drive doesn’t detect
the PG disconnection and the fault E025 is
masking.
A7.05 Reduction rate of
motor and encoder
This parameter should be set to 1 when the encoder
is connected to the motor axis directly. Or if there is
reduction rate between motor axis and encoder,
then please set this parameter according to the
actual situation.
6.9 Group A8
A8.00 Protective action of relay
A8.01 Fault masking selection 1
A8.02 Fault masking selection 2
Please set the fault masking selection
function carefully, or it may cause worse accident, bodily
injury and property damage.
A8.03 Motor overload protection
mode selection
0： Disabled
The overload protection is disabled. Be careful to
use this function because the drive will not protect
the motor when overload occurs.
1： Common motor (with low speed compensation)
Since the cooling effects of common motor
deteriorates at low speed (below 30Hz), the motor’s
overheat protecting threshold should be lowered,
which is called low speed compensation.
2 ： Variable frequency motor (without low speed
compensation) The cooling effects of variable
frequency motor is not affected by the motor’s
speed, so low speed compensation is not
necessary.
Auto reset function can reset the fault in preset
times and interval. When A8.04 is set to 0, it means
“auto reset” is disabled and the protective device
will be activated in case of fault.
Note：
The IGBT protection (E010) and external equipment
fault (E015) cannot be reset automatically.
