Technical Details
The following four input signals from the U500/U600 board are +5 volt logic level
signals used to enable the drive modules. There is a pull up resistor (10K ohm typical) on
each of these inputs. These inputs require the logic level to be low to engable the drive
module in a standard configuration. If this input is set to a logic high (+5 volts), or is
unconnected, the drive is disabled in the standard configuration. See the UNIDEX
500/U600 manuals for additional information concerning configuration of the Axis
Enable signals.
Pin 69 - Axis Enable 1 Input
Pin 70 - Axis Enable 2 Input
Pin 71 - Axis Enable 3 Input
Pin 72 - Axis Enable 4 Input
The following four Axis Fault signals are 5 volt logic level outputs. These outputs
indicate an axis drive fault when the logic level is low. See the UNIDEX 500/U600
manuals for additional information concerning Axis Fault signals.
Pin 73 - Axis Fault 1 Output
Pin 74 - Axis Fault 2 Output
Pin 75 - Axis Fault 3 Output
Pin 76 - Axis Fault 4 Output
Each of the following four pairs of inputs are the analog current command signals for the
drive modules. The current commands are generated on the U500/U600 board by a serial
D/A converter with 16 bit resolution scaled to a range that includes -10 to +10 volts (See
the U500/U600 manuals for additional information). Each axis has two current commands
associated with it. The first commands DC brush motors and the second (or phase two
command output) is used in addition to the first to generate a quadrature, or a 120° offset
current command, for stepping or AC brushless motors.
Pin 79 - Current Command Axis 1
Pin 80 - Current Command Axis 1 Phase 2
Pin 81 - Current Command Axis 2
Pin 82 - Current Command Axis 2 Phase 2
Pin 83 - Current Command Axis 3
Pin 84 - Current Command Axis 3 Phase 2
Pin 85 - Current Command Axis 4
Pin 86 - Current Command Axis 4 Phase 2
