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 = minimum speed to maximum speed.

Wiring Start / Stop Control

Important:

The terminal block start function is only active when in terminal block
start mode.

The system looks for an open-to-closed transition at the Start input before starting the
unit unless you have the Run on Power Up 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.

The jumper between terminals 13 and 17 must be removed when wiring the Stop input.

Refer to Chapter 8 to select a stop method via SW3 Selector Switch.
