The standard setpoint controlling the SED2 is via AIN1.
ESM setpoint is via a Fixed Frequency.
(See also next section on “disabling the Additional Setpoint”)
P1000 in000 = 23
The standard setpoint controlling the SED2 is via a LON system (optional LON
module needs to be connected).
ESM setpoint is from a Fixed Frequency
(Note: Next section on “disabling the Additional Setpoint”).
P1000 in000 = 73
Any of the combinations shown in the chart can be used.

In the above examples of defining the setpoint for standard and ESM, it is very im-
portant to ensure that when ESM is activated that it disables the standard setpoint
otherwise the two setpoints will add.
6.3.4 Basic settings as ESM Fixed Frequency setpoint
The most common method of ESM speed control is a preset fixed frequency.
