A309 Stall Current Limit
Selection
1 1 2 1 Select stall current limit..
=1: Local
=2: Terminal
When local is selected, B301 will be effective.
When terminal is selected, stall current limit is
set by the 0-10V analog signal at Vin.

A403 Base Frequency % 100.0 5.0 100.0 0.1 This is output frequency at which the output
voltage reaches to Base Voltage A404 and than
after remains constant. This is percentage of
Motor Frequency B104.
A404 Base Voltage % 100.0 0.1 100.0 0.1 This is the maximum output voltage available at
Base Frequency A403. This is percentage of
Motor Voltage B102.
A405 VF1 Frequency % 25.0 1.0 100.0 0.1 These parameters are used to create the
custom V/Hz profile. Three different points for
the curve can be defined to get the profile
suitable for the application.
A405 <= A406 <= A407
A408 <= A409 <= A410.
A405~A407 are percentage of A403 and
A408~A410 are percentage of A404.
A406 VF2 Frequency % 50.0 1.0 100.0 0.1
A407 VF3 Frequency % 75.0 1.0 100.0 0.1
A408 VF1 Voltage % 25.0 0.1 100.0 0.1
A409 VF2 Voltage % 50.0 0.1 100.0 0.1
A410 VF3 Voltage % 75.0 0.1 100.0 0.1
