Status diagnoses
"Ready"
drive ready
for powering up
Status diagnoses are signals referring to the operational readiness of the
drive. They are displayed on the status indicator H1.
When the control voltage has been applied and the drive is free of errors,
the status indicator "H1" will display the message "bb".
Once the mains power has been switched on the status indicator "H1" will
switch to "Ab" (drive ready)
Application of the controller enable signal will enable the internal control
circuits.
To avoid unnecessary production stoppages, the digital AC servo drive
is equipped with a temperature monitoring feature for both the drive
controller and the AC servo motor.
The causes of overheating may be:
– Contamination of heat transfer points
– Overloading due to the machine’s work cycle
– Failure of the cooling system in the drive controller
– Failure of the cooling system on the AC servo motor
The temperature of both the drive controller and the servo motor are monitored
continuously and separately. When the temperature rises above the permissible
limit an overtemperature warning signal is emitted for 30 s.
The following temperature warnings are emitted as flashing messages:
"Warning: amplifier overtemperature"
"Warning: motor overtemperature"
"Drive ready"
for power output
"Drive enable"
