Running
4.1
Trial running with no load
The purpose of the trial run is to confirm whether the following matters are correct:
Driver power wiring;
Servo motor power wiring;
Encoder wiring;
Direction and speed of servo motor.
4.1.1
Wiring and inspection
Before energizing, verify that the motor:
Motor no load, do not add load on the motor shaft, has been installed on the machine,
please remove the connector.
The motor must be fixed because of the impact of motor acceleration and deceleration.
Check the following before turning on the power:
Is the connection correct? In particular, whether the drive U, V, W and motor U, V, W
wiring one to one corresponding to the drive L1, L2, L3, L1C, L2C, 24V, 0V wiring.
Is the input voltage correct?
Is the encoder cable connected correctly?
4.1.2
Trial running in JOG mode
Note: keyboard speed test run, need to set parameter P304 (PROFINET mode switch) to
0 to run!
When parameter P304 is 0, the driver is in normal mode, which can be used for keyboard
speed control trial operation and other functions; When parameter P304 is 1, the driver is in
PROFINET mode, and the control mode and instructions are all from PROFINET bus. After
changing parameter P304, the parameters must be stored in EEPROM, and the drive power off,
and then re-energized to run, can take effect!
1. Before performing this operation, verify that the motor is unloaded.
2. Switch on the POWER supply (AC three-phase 220V or AC single-phase 220V), the
display of the driver will be on, and the POWER indicator will be on. If there is an alarm,
please check the connection.
3. After confirming that there is no alarm or abnormity, and when the parameter P304 of
EP3E is 0, perform the following operations as shown in the figure below:
