4-Q-DC Servoamplifier ADS 50/5
Operating Instructions
7
Operating Status Display
A two coloured red/green LED shows the operating mode.
7.1
No LED
Reason:
•
No supply voltage
•
Fuse
fault
•
Wrong polarity of supply voltage
•
Short circuit of the +5 V output
7.2
LED shines green
Blink pattern (green LED)
Operating Conditions
Amplifier is activated (Enable)
Disable function active
7.3
LED shines red
According to the blink pattern the following error messages can be identified:
Blink pattern (red LED)
Operating Conditions
c
If the power stage temperature ex-
ceeds a limit of approx. 90°C, the
power stage is switches off (disable
status).
d
If a motor current of more than ap-
prox. +/- 12.5 A is detected at the
current actual value, the power stage
will be switched off (disable status).
e
If the internal supply voltage cannot
be set-up as expected the power
amplifier is switched off (disable
status).
f
If the input frequency at the encoder
input is > 150 kHz, the power ampli-
fier is switched off.
The fault condition is stored. In order to reset the fault condition, the servoampli-
fier must be re-released (Enable). If the cause of the fault condition cannot be
eliminated, the error output will be disabled again immediately.
Reason:
•
High ambient temperature (blink pattern
c
)
•
max. continuous current > 5 A (blink pattern
c
)
•
bad convection (blink pattern
c
)
•
Short circuit on the motor winding (blink pattern
d
)
