Some USB-to-RS232 converters can unintentionally activate the firmware download mode,
as long as they have not been initialised by DSerV yet. Remedy: Switch off the supply voltage.
Only connect the RS232 cable once the supply is switched on.

Attention !
The power supply must be switched off before you begin with the troubleshooting!
An internal error memory enables the display of even short-term error signals.
The occurrence of an error leads to the shut-down of the power stage, i.e. the motor power is disconnected.
Errors are shown with the red LED of the status display by means of a blink code, whereby the number of light pulses
corresponds to the error code. The error table provides an indication of the cause of error. The service software DSerV
shows the cause of error in plain text. If multiple causes of error are present at the same time, the highest error code is
displayed.
After rectification of the corresponding cause of error, an error message can be reset by switching the enable input DI1
"OFF - ON". The power stage and the controller are only activated after switching the enable input "OFF - ON" a second
time:
Fig.: Error logic
t1:
Occurrence of an error: Power stage disabled immediately; error message active
t2:
Error cause is rectified.
t3:
Enable input set to inactive by user.
t4:
Enable input set to active by user (1st rising edge): Power stage / controller remains disabled.
t5:
Enable input set to inactive by user: Error message is reset, ready message follows.
t6:
Enable input set to active by user (2nd rising edge): Power stage and controller become active.
The resetting of an error message is also possible by switching the drive off and on again.
Note: Error 10 "internal error" cannot be reset with the enable input.
