2.8.11.8.1 +/- speed of reference range
The reference is supplied by Fr1 or Fr1b ; if necessary with the functions summation/subtraction/multiplication
and the preset frequencies ( see "Reference channel design 1" on page 186 ). For the sake of simplicity, this will
hereinafter be called Reference A. The action of the + speed and - speed keys can be set to a percentage of
Reference A. On stopping, the reference (A ± speed) is not saved. The inverter then runs with only one reference
A+.
The maximum total reference value is limited by [high speed] (HSP) and the minimum reference
by [low speed] (LSP) ( see "Parameters that can be modified during operation or when the motor is stopped."
on page 130 ).
Example of 2-wire control:
Motor frequency
[Acceleration 2] (AC2)
[Deceleration 2] (dE2)
