ConTRol InPUTS AnD oUTPUTS
EnABlE InPUT
The Enable input [In1] is lo-active and pulled up to +5V by an internal 10k resistor. This
provides fail-safe operation by disabling the amplifier if the Enable input is open, or a wire
from the controller should break.
FwD/REV EnABlE InPUTS
Two inputs are provided for limit switches.
These should be lo for normal operation, and open or HI to inhibit current of positive or
negative polarity.
loAD InDUCTAnCE InPUT
The /LowInd input controls the gain of the current error amplifier to compensate the amplifier
for lower or higher inductance loads. with the input open, the bandwidth will be ~2.5 kHz
for a 2 mH (line-line) load. Grounding the input reduces the gain to 1/10 of the input-open
gain for the same bandwidth with 200 µH loads.
AnAloG REFEREnCE InPUT
The amplitude and polarity of the amplifier output current is controlled by a ±10V analog
signal from an external controller.
BAlAnCE InPUT
The output current of the amplifier can be adjusted to 0 Adc by connecting the balance input
to a potentiometer with an adjustment range of 0 to +5 Vdc. This will produce an offset
adjustment range of ±0.8% of the Ipeak rating of the amplifier. The table below shows the
offset adjustment range in mA.

DIGITAl oUTPUTS
Three n-channel MoSFETs sink current from loads connecting to +30 Vdc maximum. outputs
[Aok] and [oUT1] can sink 100 mA maximum. The brake output [oUT2] can sink 1000 mA.
An external flyback diode is required with driving inductive loads like a brake, or relays.
