Minimum field frequency f
dmin
You can use code C010 to program a minimum output frequency.
This changes the influence of the analog set-value to set-value 1 in
the factory-set configuration C005 = -0- (not for other
configurations).

Maximum field frequency f
dmax
Via C011, you can select a maximum field frequency between 7.5
and 480 Hz. The value will be a reference for the analog and
scaled set-value input and for the acceleration and deceleration
times. For absolute set-value input, e.g. via keypad or JOG
frequencies, f
dmax
is the limit value.
With a configuration with PI controller (C005 = -10-...-15-), the
output frequency can be up to 200% f
dmax
.
When you want to change the maximum field frequency in large
increments via the LECOM interfaces, first inhibit the controller.
