Shunt Regulator (90V, 64V, 33V)
The AMP-19520/40 has an OPTIONAL internal shunt regulator (for example, order AMP-19540-SR). A shunt regulator
is a power resistor and switch connected across the power supply used to dissipate energy fed back to the amplifier from
the motor. This keeps the power supply voltage from exceeding hazardous levels.
The shunt regulator is unused when no jumper is installed (an OVERVOLTAGE error condition will occur if the supply
voltage exceeds 94 V). Install a single jumper on the desired voltage threshold (90V, 64V, or 33V) to use the shunt
regulator. The switch will close when the power supply's capacitor exceeds the voltage threshold. The voltage threshold
chosen should be the one just higher than the nominal supply voltage (e.g. use the 33 V jumper when using a 24 V
supply).

Amplifier Error Monitoring
When an amplifier error occurs (UNDERVOLTAGE, OVERCURRENT, OVERVOLTAGE, or OVERTEMP), the AMP
ERR digital output is brought low. Insert either the 7_IN or ABORT jumper to notify the controller of these conditions.

ELO
ELO (Emergency Lock Out) is a jumper setting on the AMP-195x0 which configures the amplifier's behavior when the
abort line goes low. With the jumper absent (default), the behavior of the motors is subject to the OE command. If the
jumper is installed, the amplifiers will be immediately shut down, leaving the axes in a free-spin state. Having the ELO
jumper installed is similar to OE1, except that the amplifiers are disabled in hardware rather than firmware. WHEN
ELO IS INSTALLED, OE SHOULD BE SET TO 1. To recover, issue MO; SH. When ELO is active, the overcurrent
and overvoltage lights will turn on.

7_IN
Install this jumper to tie the amplifier's AMP ERR digital output to digital input 7 on the controller. This jumper allows
the controller to handle an amplifier error condition for example by issuing the ST command from #ININT (see II in the
command reference). INCOM MUST BE POWERED WITH OPTIMA CONTROLLERS
ABORT
Install this jumper to tie the amplifier's AMP ERR digital output to the controller's Abort digital input. When the Abort
input is brought low, the controller will stop program execution and bring all axes to an instantaneous stop (OE0) or
allow the motors to coast (OE1). INCOM MUST BE POWERED WITH OPTIMA CONTROLLERS
CHOP
Install for chopper mode (for low inductance motors), otherwise the amplifier operates in inverter mode (Rev D or
newer).
Amplifier Gains
If AG2 and AG0 are not installed, the amplifier gain on that axis is 0.7 A/V (medium).
