minimum rated supply voltage. Under-Voltage does not latch by default. It will become a latching error after AZ2 is
issued to the controller. See the Clearing Latched Amplifier Errors section for details.
Abort/ELO Input
If the Abort Input is asserted while the ELO jumper is installed, the power stage of the amplifier will be disabled
and the ELO amplifier error will be reported. This is a latching error, see the Clearing Latched Amplifier Errors
section for details.
Clearing Latched Amplifier Errors
While all axes are in a motor off state (MO) and there are no latched amplifier errors, all amplifier errors will be
reported in real-time by the
bank must be in a servo here state (SH).
To clear latched amplifier errors, issue the
amplifier error condition is still present. If an axis is moving, motion must be halted before attempting to clear
amplifier errors. See the
examples.
External Amplifier Interface
The AMP-20545 breaks out the step/direction or amplifier enable/motor command signals to control an external
servo or stepper amplifier. For example, a machine might have two axes that use the AMP-20545 and two stepper
axes that use external drivers. The step and direction signals are accessed through the high density 44-pin D-sub
connector. The same connector pins are used to bring out the amplifier enable and motor command line. Which
signals are brought out is set via jumpers, see Figure A3.4. If no jumpers are installed (factory default), the
corresponding pins on the 44-pin connector will be no-connects. In this example, the C axis will output the motor
command on pin 31 and amplifier enable on pin 16. The D axis will output step and direction to the appropriate
pins.
