Operational Overview
Analog Output Offset units:
• Velocity Command = RPM
• Velocity Feedback = RPM
• Torque Command = Percent of continuous torque
• Torque Feedback = Percent of continuous torque
• Position Feedback = Revs
• Following Error = Revs
Analog Output Scale units:
• Velocity Command = RPM/volt
• Velocity Feedback = RPM/volt
• Torque Command = Percent of continuous torque/volt
• Torque Feedback = Percent of continuous torque/volt
• Position Feedback = Revs/volts
• Following Error = Revs/volts
Example:
You could use the Analog Outputs to accurately measure velocity overshoot. For example, to measure a target velocity
of 2000 RPM at a resolution of ±10V = ±200 RPM do the following.
1. Selected Velocity Feedback for the Analog Output Source.
2. Set the Analog Output Offset to 2000 RPM.
3. Set the Analog Output Scale to 20 RPM/VOLT.
This will provide an active range from -10 to +10 Volts to represent 1800 to 2200 RPM. Therefore, the measured
resolution has been increased.
Digital Inputs and Outputs
External control capability is provided through the use of input and output functions. These functions may be assigned
to any input or output line on the drive or the module. After they are assigned to lines, external controllers, such as a
PLC or other motion controllers, may be used to affect or monitor the drive’s operation.
Drives are equipped with five optically isolated input lines (one dedicated to a Drive Enable function) and three optically
isolated output lines.
The drive’s input and output lines can be accessed through the 26-pin digital I/O connector (J3) on the front of the drive.
All inputs and outputs are configured as sourcing and are designed to operate from a +10 Vdc to +30 Vdc power source.
The user is responsible for limiting the output current to less than 150 mA for each digital output.
Input Lines
Active State
The active state of an input function can be programmed to be "Active Off” or “Active On” using PowerTools Pro. Making
an input function “Active On” means that it will be active when 10 Vdc to 30 Vdc is applied to the input line it is assigned
to, and is not active when no voltage is applied to the line. Making an input function "Active Off" means that it will be
active when no voltage is applied to the input line and not active while 10 Vdc to 30 Vdc is being applied.
Always Active
The user can also make an input function "Always Active", which means that it is active regardless of whether or not it
is assigned to an input line, and, if the function is assigned to an input line, it will be active whether or not voltage is
applied to that line. This is useful for testing the drive operation before I/O wiring is complete.
Debounce Time
The user can program a “Debounce Time” which means the line will need to be “On” for at least the debounce time
before it is recognized. This feature helps prevent false triggering in applications in noisy electrical environments.
