2. Fault Digital Output
On hardware revisions 1.06 and earlier:
TTL compatible OC output (5V logic). High when drive is at fault, low otherwise.
On hardware revision 1.07
TTL compatible output (5V logic). High when drive at fault or disabled, low otherwise.
3. Enabled digital input
This is a single-ended input, compatible with 5V TTL, open-collector sink output, and switch or relay
contacts. The input is referenced to drive logic common. These inputs are active low, i.e., connecting it to
drive logic common or supplying logic "0" referenced to drive logic common activates this input. For
connection guidelines see application note in Appendix A. See figure below for electrical diagram.
4. Analog reference input
IN+, IN- (TB2-4,TB2-5)
Analog differential input. This input will accept +/-10V single-ended voltage on IN+ or IN- input or +/-5V
differential voltage between IN+ and IN-. Both connections must be referenced to Analog Common
(TB2-2) of the drive. This input is used to control speed or torque of the motor in velocity or torque
mode. The total reference voltage as seen by the drive is the voltage difference between IN+ and IN-. If
used in single-ended mode one of the inputs must be connected to voltage source while the other one
must be connected to Analog Common. If used in differential mode, the voltage source is connected
across IN+ and IN- inputs and driving circuit common (if any) needs to be connected to drive Analog
Common terminal.
Reference as seen by drive: Vref = (VIN+) - (VIN-)
Example #1:
Vin+ = 2V
Vin- =0 (connected to analog ground)
Vref = (2V) - (0V) = 2V (as seen by drive)
Example #2:
Vin+ = 2V
Vin- = -1V
Vref= (2V) - (-1V) = 3V (as seen by drive)
Example #3:
Vin+ = 2V
Vin- = 1V
Vref = (2V) - (1V) = 1V (as seen by drive)
