(4) Grounding
In order to prevent electric shock, be sure to ground the reactor, noise filter, driver;
When multiple servo drivers are used, do not connect the ground cables of multiple servo drivers in
series. Instead, use the single-point grounding method.
The driver should be grounded with the shortest possible cable (>2mm²). If the ground cable is longer,
increase the diameter of the ground cable (≥4mm²).
3.2.3 Overload protection of servo
The driver calculates the heat by the output current, and implements the overload protection
function for the driver and the motor. Overload protection means that when the driver and motor
exceed the rated current, continuous use cannot be guaranteed, and only overload operation can
be carried out under the overload protection characteristics.
Because the driver and the motor work at the same time, if the load rate of the motor reaches
100% first, the overload alarm protects the motor; When the load rate of the driver reaches 100%
before the motor, the overload alarm protects the driver.
Standard motor has no temperature sensor for overheating protection, can not real-time
monitoring of the actual temperature of the motor, if there are special conditions to detect the
real-time temperature of the motor, please consult our sales staff.
Note
After the driver or motor IIT failure (fault code: 080.0), driver output short circuit
(fault code: 008.0), driver bus voltage is too high (fault code: 002.0) and other
alarms, stop the fault first, check the cause of the fault, and then try to run. If the
root cause of the fault is not identified, a high-frequency reset may cause damage
to the drive hardware.
