Fault Messages
Fault Name
EE-PROM write-in and read-out is in error.
The communication between DSP and MCU is in error. DSP do
not respond to MCU command. The problem is on DSP side.
RS232/485 communication is in error.
RS232/485 communication time out.
One phase of the input power is loss.
To warn that the servo motor and drive is going to overload. This
alarm will display before ALM06. When the servo motor reach
the setting value of P1-56, the motor will send a warning to the
drive. After the drive has detected the warning, the DO signal
OLW will be activated and this fault message will display.
An error occurs when internal command is executing.
1. DSP do not respond to MCU command.
2. DSP has responded to MCU command but there is error in
