Emotron AB 01-4429-01r2 Functional Description 93
Preset Ref 1 [362] to Preset Ref 7
[368]
Preset speeds have priority over the analogue inputs. Preset
speeds are activated by the digital inputs. The digital inputs
must be set to the function Pres. Ref 1, Pres. Ref 2 or Pres.
Ref 4.
Depending on the number of digital inputs used, up to 7
preset speeds can be activated per parameter set. Using all
the parameter sets, up to 28 preset speeds are possible.
Communication information
The same settings are valid for the menus:
[363] Preset Ref 2, with default 250 rpm
[364] Preset Ref 3, with default 500 rpm
[365] Preset Ref 4, with default 750 rpm
[366] Preset Ref 5, with default 1000 rpm
[367] Preset Ref 6, with default 1250 rpm
[368] Preset Ref 7, with default 1500 rpm
The selection of the presets is as in Table 24.

= selected if only one preset reference is active
1 = active input
0 = non active input
Keyboard reference mode [369]
This parameter sets how the reference value [310] is edited.
Communication information
11.3.8 PI Speed Control [370]
The VSD has an internal speed controller, which is used to
keep the shaft speed equal to the set speed reference. This
internal speed controller works without an external feed-
back.
With the parameters speed P gain [372] and speed I time
[373] the controller can be optimized manually.
Speed PI Autotune [371]
The function speed autotune will perform a torque step
change, and measures the reaction on shaft speed.
It automatically sets the internal speed I time to its optimum
value. The speed PI autotune must be done during opera-
tion with the motor load connected and the motor running.
“Spd PI Auto” will be blinking in the display during the

Default: Normal
Normal 0
The reference value is edited as a normal
parameter (the new reference value is
activated when Enter is pressed after the
value has been changed). The Acc Time
[331] and Dec Time [332] are used.
MotPot 1
The reference value is edited using the
motor potentiometer function (the new
reference value is activated directly when
the key + or - is pressed). The Acc MotPot
[333] and Dec MotPot [334] are used.

NOTE: When Key Ref Mode is set to MotPot, the
reference value ramp times are according to the Acc

speed ramp will be limited according to Acc Time [331]
and Dec Time [332].
