215 Preset reference 1 (PRESET REF. 1)
216 Preset reference 2 (PRESET REF. 2)
217 Preset reference 3 (PRESET REF. 3)
218 Preset reference 4 (PRESET REF. 4)
Value:
-100.00 % - +100.00 %
of the reference range/external reference
Function:
Four different preset references can be programmed
in parameters 215-218.
The preset reference is stated as a percentage of
the value Ref or as a percentage of the other
MAX
external references, depending on the choice made in
parameter 214. If a Ref
MIN
the preset reference as a percentage will be calculated
on the basis of the difference between Ref
Ref , following which the value is added to Ref
MIN
Description of choice:
Set the fixed reference(s) that is/are to be the options.
To use the fixed references, it is necessary to
have selected Preset ref. enable on terminal
16, 17, 29, 32 or 33.
Choices between fixed references can be
made by activating terminal 16, 17, 29, 32 or
33 - see the table below.

221 Torque limit for motor mode
(TORQ LIMIT MOTOR)
Value:
0.0 % - xxx.x % of T
M,N
Function:
This function is relevant for all application
configurations; speed, process and torque control.
This is where to set the torque limit for motor operation.
The torque limiter is active in the frequency range up
to the rated motor frequency (parameter 104).
In the oversynchronous range, where the frequency
is higher than the rated motor frequency, this
function acts as a current limiter.
See fig. below.
Description of choice:
See also parameter 409 for further details.
In order to protect the motor from reaching pull-out
torque, the factory setting is 1.6 x the rated
motor torque (calculated value).
If a synchronous motor is used, the torque limit must
be increased in relation to the factory setting.
