LINE-POWERED AC BRUSHLESS SERVO AMPLIFIERS
WITH +/-10V ANALOG U-V INPUTS
STATUS SIGNALS
CURRENT-LIMIT OUTPUT
This is an output signal which is HI (+5V) when the amplifier is
not current limiting. As the current limiting starts to take effect
the /CLIMIT output will go LO (0V).
This is very useful for a closed loop control system that expects
the amplifier to be operating in a linear manner. Since, the
/CLIMIT line transitions LO on the first detection of current
limiting, the controller can be alerted to non-linear behavior
immediately.

Ready = Amp OK AND NOT enabled
Normal = Amp OK AND enabled
Amp OK = Internal buss voltage is within limits AND
NOT Fault
Fault = Over voltage, under voltage, or motor
overtemp.
Latching Fault = Output short circuit or heatplate
overtemperature. Amplifier latches off and
stays off until reset.

N-channel mosfet with 10k-ohm resistor connected to +5V.
Maximum voltage: 50VDC. Maximum current 250 mA.
On-resistance = 5 ohms.
Output is LO (mosfet ON) whenever amplifier is enabled and
NORMAL (LED Green)
Output is HI (mosfet OFF) whenever amplifier is NOT enabled,
or FAULT occurs.
OPTO-ISOLATED NORMAL OUTPUT
SIGNAL
This AMP OK signal indicates that the amplifier ready to run. It
is completely optically isolated from the amplifier. The input of
the optocoupler is driven by the amplifier logic circuits, and the
output is a floating NPN transistor with both terminals brought
to signal connector J3 as shown below.
