Note: cautions for test mode (terminal forced output control, JOG test, positioning test)
When using the communication commands in the test mode, the user must pay attention to the
following matters, otherwise the drive will not work normally in the test mode.
1.The drive can enter the test mode only when there is no alarm and the servo is off.
2.In the test mode, if the communication is interrupted for more than 1 second, the drive will
switch to Servo Off status and exit the test mode. Therefore, the Host device should perform
uninterrupted communication in the test mode (each communication command interval should
be within 1 second). There are no special restrictions on the communication command
address. For example, you can repeat the read command to the communication address
0x0900 to maintain the continuous communication state.
3.After entering the test mode (terminal forced output control, JOG test, positioning test), the
normal external hardware signal and software contact signal are invalid, except the EMG
signal.
(8) DO forced output (readable and writable)
Step 1: read the alarm and Servo ON information from the following communication
address to make sure that there is no alarm and the servo is in servo Off status currently,
otherwise it will not enter test mode.
