Input Configurations
The following input configurations are available for the position command input.
PWM
The PWM input will accept a 1000±100 Hz input signal of 5 to 32 V peak voltage
(referenced to unit battery ground). The nominal input of 10% to 90% duty cycle
will correspond to 0% to 100% actuator travel (at system calibration
temperature). The position command input will be capable of providing a
common mode input voltage range (unit battery ground referenced) of 0 to 4 V
for all inputs.
0–200 mA
The 0–200 mA input will accept a 0 to 200 mA dc input. The nominal input of 20
to 160 mA will correspond to 0% to 100% actuator travel (at system calibration
temperature). The position command input will be capable of providing a
common mode input voltage range (unit battery ground referenced) of 0 to 4 V
for all inputs.
4–20 mA
The 4–20 mA input will accept a 0 to 20 mA dc input. The nominal input of 4 to
20 mA will correspond to 0% to 100% actuator travel (at system calibration
temperature). The position command input will be capable of providing a
common mode input voltage range (unit battery ground referenced) of 0 to 4 V
for all inputs.
The following items are not longer available:
11–20 mA – No longer available
The 11–20 mA input will accept a 0 to 20 mA dc input. The nominal input of 12 to
20 mA will correspond to 0% to 100% actuator travel (at system calibration
temperature). The position command input will be capable of providing a
common mode input voltage range (unit battery ground referenced) of 0 to 4 V
for all inputs.
4–13 mA – No longer available
The 4–13 mA input will accept a 0 to 20 mA dc input. The nominal input of 4 to
12 mA will correspond to 0% to 100% actuator travel (at system calibration
temperature). The position command input will be capable of providing a
common mode input voltage range (unit battery ground referenced) of 0 to 4 V
for all inputs.
0–5 Volt – No longer available
The 0–5 V input will accept a 0 to 5 Vdc input. The nominal input of 0.5 to 4.5 V
will correspond to 0% to 100% actuator travel (at system calibration
temperature). The position command input will be capable of providing a
common mode input voltage range (unit battery ground referenced) of 0 to 4 V
for all inputs.
System Performance
The performance of the driver when mated to a ProAct II actuator will be as
follows:
Inertia level
The driver mated to a ProAct II actuator can drive inertial loads not to exceed
5.9*10
–3
in-lb-sec². This is specified as un-damped direct inertia.
