is over 120°C.
9-12
Checking Method
1. Check if the servo is properly
grounded.
2. Check if the encoder cable
separates from the power supply
or the high-current circuit to avoid
the interference.
3. Check if the shielding cables are
used in the wiring of the encoder.
Checking Method
1. Check if P1-57 is enabled.
2. Check if P1-57 is set too small
and the time of P1-58 is set too
short.
Checking Method
Check if U, V, W of the motor is
incorrect connected or the
connection is breakdown.
Checking Method
Check if the environment
temperature is excessive or the
motor temperature is over 105°C.
Corrective Actions
1. Please connect the UVW
connector (color green) to
the heat sink of the servo
drive.
2. Please check if the
encoder cable separates
from the power supply or
the high-current circuit.
3. Please use shielding
mesh.
4. If issue persists, please
send the drive back to the
distributors or contact
Delta.
Corrective Actions
1. If it is enabled by mistake,
please set P1-57 to zero.
2. According to the actual
torque setting, if the value
is set too small, the alarm
will be triggered by
mistake. However, if the
value is set too big, it will
lose the function of
protection.
Corrective Actions
Follow the user manual to
correctly wire U, V, and W
and make sure it is
grounded.
Corrective Actions
Try to reduce operating
temperature.
