As noted, the data buffer length is limited, but DAQ has extensive triggering that allows you to capture the exact
data that you need.
Table 8.11 lists the triggers available.
Table 8.11: DAQ Trigger Descriptions
Trigger Description
Absolute value of leg
current exceeds
specified level Set an amperage level, and the trigger occurs when the composite leg current
exceeds that level.
Acceleration exceeds
trigger level Set an acceleration level, and the trigger occurs when the Danfoss Power
Solutions motor’s acceleration exceeds that level.
Bus current reaches
trigger level
Set an amperage level, and the trigger occurs when the bus current passes
through that level from either direction.
Bus voltage reaches
trigger level Set a voltage level, and the trigger occurs when the bus voltage passes through
that level from either direction.
CANbus changes the
control mode A trigger occurs when the controller’s control mode (torque or speed) changes
through the CANbus.
Desired Torque
becomes dynamic A trigger occurs when a significant change in desired torque is detected.
Desired Torque
becomes steady state A trigger occurs when no significant change in desired torque is detected over a
period of time.
Direction (actual)
changes A trigger occurs when the motor’s direction changes from forward to reverse, or
reverse to forward.
Direction (desired)
changes A trigger occurs when the demanded direction changes from forward to reverse,
or reverse to forward.
Electrical Power reaches
trigger level Set a wattage level, and the trigger occurs when the electrical power passes
through that level from either direction.
Forced voltage control
occurs A trigger occurs when the controller is in forced voltage control, which is a safety
mode entered only when bus voltage reaches a dangerous level.
Inverter fault occurs A trigger occurs when any controller module faults. Over current and over
temperature problems can cause these modules to fault when they are switching
power. A drop in the 15 V supplying the modules also triggers a controller fault.
It is also possible for a false trigger to occur when the bus voltage drops below
the necessary level for controller module operation. This trigger is a default
trigger.
