2-10 Brake Function
Option:
Function:
Available selections depend on
parameter 1-10 Motor Construction
:
[0] Asynchron:
[0] off
[1] Resistor brake
[2] AS brake
[1] PM non-salient:
[0] off
[1] Resistor brake
[0] Off
No brake resistor installed.
[1] Resistor
brake
Brake resistor incorporated in the system, for
dissipation of surplus braking energy as heat.
Connecting a brake resistor allows a higher DC
link voltage during braking (generating operation).
The resistor brake function is only active in
adjustable frequency drives with an integral
dynamic brake.
[2] AC brake AC Brake will only work in Compressor Torque
mode in
parameter 1-03 Torque Characteristics
.
2-17 Over-voltage Control
Option:
Function:
[0]
Disabled
No OVC required.
[2]
*
Enabled
Activates OVC.
NOTICE!
Parameter 2-17 Over-voltage Control
will not have effect
when
parameter 1-10 Motor Construction
= [1] PM, non-
salient SPM.
NOTICE!
The ramp time is automatically adjusted to avoid
tripping of the adjustable frequency drive.

backUnit]
Enter the Minimum Reference. The
Minimum Reference is the lowest
value obtainable by summing all
references. The Minimum Reference
value and unit matches the config-
uration choice made in
parameter 1-00 Configuration Mode
and
parameter 20-12 Reference/
Feedback Unit
, respectively.
NOTICE!
This parameter is used in
open-loop only.
3-04 Reference Function
Option:
Function:
[0] Sum
Sums both external and preset reference
sources.
[1] External/
Preset
Use either the preset or the external reference
source.
Shift between external and preset via a
command on a digital input.
