4 to 20 mA External Speed Reference
To use an external 4 to 20 mA signal to set the speed reference, connect the signal leads
as shown in Figure 7.11. 4 to 20 mA = 0 to maximum speed.

7.6 Wiring Start / Stop Control
Important: This applies to standard units only.
The system looks for an open-to-closed transition at the Start input before starting the
unit unless you have the Power-Up Start switch (setup DIP switch 1, see Section 8.3.1)
set to ON. If you use a maintained start device and power to the unit is lost, you must
open and reclose the start device before the unit will start again. Both the Stop and the
Function Loss input signals must be present and there must be no active faults for the
unit to start.
In order for the unit to run, you must maintain a signal at the Stop input. If the signal is
interrupted, the unit coasts to rest (default) or ramps to rest (user option). To restart the
unit, you must restore the signal and reassert the Start input.
