1.3.2 Mechanical
1.3.1.3 Digital Inputs:
+/-Limit, Inhibit & Reset:
40/-0.5V max. Terminated by 10,000S.
Fault (as input):
40/-0.5V max. Terminated by 10,000S.
Typical for all digital inputs: Digital inputs have hysteresis with thresholds
at 1/3 and and 2/3 of +5V or +15V depending on
range
select
jumper.
1.3.1.4 System:
Drift offset over temperature reference to input:
0.01mV/
o
C max.
Frequency response (Velocity loop):
750Hz min.
Frequency response (Current loop):
2KHz min.
Dead band:
None.
Form factor:
1.01.
1.3.1.5 Outputs:
•
Fault (as output):
Active low. Open-collector output can sink 500mA max.
•
Absolute motor current(J1-3):
10A/V.
•
Tachometer :
1000S source impedance, a high input impedance meter must
be used (1M S /volt). Maximum Tachometer output voltage
for 12 bit = 1.5V/KRPM, 14 bit = 2V/KRPM.
•
Encoder outputs:
Standard TTL levels with 20mA sink or source capability.
