SD710 Series Servo Drive User Manal Chapter 10 Troubleshooting
15
Error code
ER. 0b0
ServoON command invalid
Reason
When using certain auxiliary functions, Servo is also enabled by means of them.
Treatment.
Reasons
Confirmation method
Handling measures
1. Internal enable (Pn001.X = 1).
◆
Check if the auxiliary function is
used, while internally enabling
Invalidate the internal enable
setting.
2. External enable signal (s-on) is
active.
◆
Check if the auxiliary function is
used while the external terminal is
enabled
Set the external X terminal S-ON
signal to inactive.
Error code
ER. 100
Servo overcurrent (software)
Error code
ER. bf4
Servo overcurrent (hardware)
Reason
The output current of the exceeds the set threshold.
Treatment.
Reasons
Confirmation method
Handling measures
1. Short circuit in motor
cable U, V, W.
◆
Check whether the motor power cable
U, V, W is short-circuited, and whether the
connector wire has burrs
Connect the motor cables correctly.
2. Grounding of motor
cables U, V and W.
◆
Check the insulation resistance
between the motor power cable U, V, W
and the motor wire. Measure the
insulation resistance between the U, V
and W ends of the and the ground wire
(PE) for megohm (MΩ) level values
Replace the motor with a new one if
the insulation is poor.
3. Motor burnout.
◆
Check that the resistance between
the wires of the motor is balanced.
If it is not balanced, the motor needs
to be replaced.
4. Poor contact with the
motor power cable.
◆
Check whether the connector
terminals of U, V and W of the motor
connection are off
If loose and dislodged, tighten.
5
、
The gain setting is not
reasonable and vibration
occurs
during
motor
operation.
◆
When motor in the starting and
running process, whether the motor has
vibration or strange noise.
Make gain adjustments.
6. The braking resistor is
too small or short-circuited.
◆
If using built-in braking resistor,
confirm that the measurement is reliably
connected between B2/B3 with wires, and
if so, measure the resistance value
between P/B3.
◆
If external braking resistor is used,
make sure the resistance value of external
braking resistor between P /B2 is
measured.
If the resistance value is infinity "∞",
the brake resistor is internally
disconnected:.
If using an internal braking resistor,
adjust to use an external braking
resistor and remove the wire
between B2/B3, the resistor
resistance and power supply can be
selected to match the internal
braking resistor.
If an external braking resistor is
used, replace it with a new one and
reconnect it between P
/B2.
7. Wrong encoder wiring,
loose plug.
◆
Check if you use our standard
Encoder cable, with or without loose
connectors.
Resolder, plug in, or replace the
encoder cable.
