[1] Resistor brake
No brake resistor installed.
Brake resistor incorporated in the system, for dissipation of surplus brake energy as heat. Con-
necting a brake resistor allows a higher DC link voltage during braking (generating operation).
The Resistor brake function is only active in frequency converters with an integral dynamic brake.
AC Brake will only work in Compressor Torque mode in par. 1-03
Function:
No OVC required.
Activates OVC.
Over-voltage Control will not have effect

Function:
Enter the Minimum Reference. The Minimum Reference is the lowest value obtainable by sum-
ming all references. The Minimum Reference value and unit matches the configuration choice
made in par. 1-00
Function:
Sums both external and preset reference sources.
Use either the preset or the external reference source.
Shift between external and preset via a command on a digital input.
Function:
Enter up to eight different preset references (0-7) in this parameter, using array programming.
The preset reference is stated as a percentage of the value Ref
ence , for closed loop see par. 20-14 Maximum Reference/Feedb. ). When using preset references,
select Preset ref. bit 0 / 1 / 2 [16], [17] or [18] for the corresponding digital inputs in parameter
group 5-1* Digital Inputs.
