Chapter 7 Running
7.1 Grounding
Ground the servo drive and motor reliably. To avoid electric shock, the protective ground
terminal of the servo drive is
The protective ground of the control box is always on. Since the servo driver uses PWM
technology to power the servo motor through the power tube
Power supply, drivers and cables may be affected by switching noise. In order to comply with
EMC standards, the grounding wire is exhausted.
Possible coarse, the grounding resistance is as small as possible.
7.2 Working sequence
7.2.1 Power-on sequence
Connect the power supply to the main circuit power input terminal through the
electromagnetic contactor.
2. The power supply of the control circuit r, t is connected to the main circuit
power supply at the same time or before the main circuit power supply. If only
the control is turned on
The power supply of the circuit, the servo ready signal (SRDY) OFF.
3. After the main circuit power is turned on, the delay is about 1.5 seconds, the
servo ready signal (SRDY) is ON, and the servo can be accepted at this time.
Service enable (SON) signal, detection of servo enable is valid, base circuit is on,
motor is energized, is running
status. The servo enable is detected to be invalid or there is an alarm, the base
circuit is turned off, and the motor is in a free state.
4. When the servo enable is turned on with the power supply, the base circuit
turns on after approximately 1.5 seconds.
Frequently turning on and off the power supply may damage the soft start
circuit and the dynamic braking circuit.
It is made 5 times an hour, 30 times a day or less. If the drive or motor is over-
heated, after the cause of the fault is removed,
It will take another 30 minutes to cool down before you can turn it on again.
